GENERAL "By their fruits shall ye know them." This passage of scripture written centuries ago- generations before the public utility business was developed- is just as applicable in our age to any sort of activity or industry as in that age. The figure of speech was at the time applied to the fruit tree. We judge the fruit tree by what it produces and we judge a business by what it brings forth and not by the manner in which production is accomplished. We may know nothing about the chemical compositions of the sap; we may know nothing about the composition of the wood; nothing about the great creative principle that builds the blossoms or moulds the fruit; but when the fruit is finally develop- ed there is not one of us so poorly informed that we cannot judge the fruit. And so we judge the tree. The best informed consumer of a utility* s commodity may know nothing about the utility’s organization, nothing about the financial condition, or about the utility’s prob- lems in disposing of its securities; he may know nothing about lines of authority in the organization, nothing about ■ : '■ ■ • ' ■ • - > * • • * i ' - the functions of the departments or duties of the employes. To him "sinking fund" or "straight line depreciation" may mean 2 . nothing if not a disease or new kind of soap. He may know no more about the details of the company’s business than one of us knows about the principles of the growth of the fruit tree; yet the most ignorant consumer will quickly know if a utility furnishes water not potable, gas that will not cook meals, or electricity that will not illuminate his living room or turn his motor. The famous passage might be modernized so as to be applicable to public utilities and stated: "By their serv- ice shall ye know them." Definition of Service Service is defined in the New Standard dictionary as "any work done for the benefit of another." Warren G. Harding, in his recent inaugural speech, made this contribution to the subject of service: "Service is the supreme commitment of life. I would rejoice to acclaim the era of golden rule and crown it with the autocracy of service." The Public Utili- ties Commission Law of the State of Illinois contains the fol- lowing: "The term ’service*, when used in this Act, is used in its broadest and most inclusive sense, and includes not only the use or accommodation afforded consumers or patrons, but also any pro- duct or commodity furnished by any public util- ity and the plant, equipment, apparatus, appli- ances, property and facilities employed by, or in connection with, any public utility in perform- ing any service or in furnishing any product or commodity and devoted to the purposes in which such public utility is engaged and to the use and accommodation of the public." * • , • . . . « ' . . 3 Maximum Service for Unit of Cost In a practical sense, however, the character of service furnished must necessarily depend on the cost of furnishing it* In very small communities where electric energy is furnished from a local plant and where no energy is necessary for power purposes the furnishing of twenty four hour service would manifestly call for an expenditure that the consumers could ill-afford to sup- port* Compliance under certain conditions with standard re- quirements of voltage regulation might require an investment out of proportion to the benefit received in way of the improve- ment in service. The distribution of locally manufactured gas in small towns, while entirely possible, is impractical for the reason that the consumers could not afford to bear the cost of furnishing gas at a profit. Individual line telephone service will not justify the cost of furnishing it in rural communities. Innumerable examples might be cited to show that the cost of furnishing a standard grade of service under certain conditions would call for a rate for the commodity which the business could not bear. The term " service” then, in its most practical and economic sense, means the greatest amount of service for unit of cost to the consumer and the standard by which it is judged should be determined by the manner in which the public will be best served. In considering the quantity of service that can reasonably be furnished to the consumer per unit of cost all the important factors that have a bearing on the business must be given consideration. The character of fuels available, the . ■ , — » . •• . . 4 . type and condition of plant and machinery in use, the size and character and location of community served, condition of the byproducts market, cost of labor and material, and the losses attendant upon distribution are factors vitally affecting the grade of service that the utility can afford to furnish and that the consumers can afford to purchase. Duplicate trans- mission lines, emergency units and standby plants may all add to the service but tend to make the cost of it prohibitive. . . , I ♦ - 5 II. FACTORS ENTERING INTO SERVICE OF PUBLIC UTILITIES In thinking of service of public utilities we are likely to have in mind only a few of the most important factors. When the average user of electric service says service is poor he usually means it is subject to frequent interruptions or possibly the voltage is low. The gas consumer makes complaint if he has difficulty in cooking and may say service is satis- factory if he has no particular trouble in this respect. The telephone subscriber says service is "rotten" if he has to wait too long for the operator to answer his signal. These are no doubt some of the most important matters to be considered in classifying service but an analysis of the records of any utility or of any regulatory body will show almost every con- ceivable objection to the service. Criticisms are made of the equipment, methods of operation, kind of treatment accorded consumers, extension policies, accuracy of meters, and many other features. In fact, the broad definition from the Public Utilities Commission Law quoted above has been found none too broad to cover the large range of subjects to which attention must be directed if patrons of the public utilities are to be satisfied. In this broad sense we are really considering the treatment accorded the consumers and every factor that en- ters into such treatment may properly be termed a factor of the service. . , , - , . . . . . > , 6 More specifically, the most important factors that en- ter into the furnishing of service by public utilities, which are described in detail in Section III, are listed in the follow- ing paragraphs: a.

NECESSITY FOR ATTENTION TO SERVICE Continuity of Service The factor entering into service by public utilities, which in most cases is the first essential to good service, is continuity* A few short interruptions at a time when they least affect the consumer need not be considered serious, but if many long interruptions occur at times when interruptions are most serious, they are provoking to the public, extremely annoying and may occasion considerable financial loss. Where interruptions are contemplated for the purpose of working on a system, some inconvenience can be spared the public if pro- per notice of such contemplated interruptions is given* In normal periods interruptions of gas or water serv- ice to an entire community are much rarer than interruptions to electric service* Plant trouble, inability to secure coal, or failure of the company* s gas holder or distribution system may cause a total Interruption. The service may be interrupted locally by restrictions in the mains or in the service pipes, and in such cases the interruptions are closely allied with, and hard to differentiate from, low or poor pressure conditions. Consumers can get along without meter tests, can put up with low voltage, or may tolerate low pressure of gas or water supply without complaint, but when the service is entire- ly interrupted every one knows it. Manufacturing may cease, business is at a standstill, and, if carried to the extent of affecting transportation, all industries may suffer and a ' 5. ‘ , t . . national crisis follow, so entirely dependent are we nowadays upon public utilities for our subsistence. This is true of service furnished by electric, gas, water, telephone utilities and railroads. These utilities are no longer luxuries. Voltage Regulation Next to continuity voltage regulation is probably the most important factor in electric utility service. The voltage regulation on some systems is so universally satisfactory that it does not occur to the consumers that poor regulation is of material consequence. In some communities, however, regulation has been found so poor as to make both lighting and power service unsatisfactory, and indeed become so serious at times as practically to constitute an interruption. Variation of voltage has a very important effect on both power and lighting service. Induction motor torque is proportional to the second power of the voltage. A reduction of ten per cent in voltage reduces the torque approximately twenty per cent. Excessive voltage causes heating of motors and an abnormal exciting cur- rent in many types of equipment. A difference of voltage on phases of polyphase machinery seriously reduces the efficiency and capacity of motors and may cause failure of the equipment. Excessive voltage impressed upon transformers frequently intro- duces harmonics into the electric lines, which cause very dis- turbing influences upon paralleling telephone lines. Tests as a result of complaints of low voltage show that heating ap- pliances often become practically worthless to the housekeeper unless the voltage is high enough to properly operate them. . , •• . , a :I ' , •• J •« , , - * 4 11 Voltage affects the life, candle power and efficiency of lighting equipment# Plate I in the Appendix shov/s the ef- fect of voltage variation on these various characteristics of the mazda lamp# Carbon lamps are even more sensitive to var- iation in voltage# These characteristics change somewhat with the development in the art of lamp manufacturing but the curves are typical of the various characteristics# Closely allied to the effect of voltage variation on multiple lamps is the change in candle power of series lamps brought about by changes in the current# Plate II sho?/s the changes in the mean horizontal candle power of a 5 .5 ampere series mazda street lamp with variation in current# The curve shows also the variation in terminal voltage and demonstrates conclusively the importance of operating series lamps at the correct rated current# A reduction of five per cent in the current causes a reduction of approximately fifty per cent in candle power, whereas practically no candle power is developed if the current is less than fifty per cent of the normal. Ef- ficiency expressed in candle power per ampere increases very rapidly near the normal current value, but the life curve of mazda lamps shows a steep decline near the point of normal cur- rent so that if excessive current is used increased efficiency is offset by cost of replacement# Frequency Regulation The variation in frequency of alternations is a phase of electric service which may very seriously affect the power user, although he may be ignorant of the cause of his trouble. , 12 The speed of synchronous motors is, of course, directly pro- portional to the frequency of the impressed voltage* The speed of induction motors is directly affected by the frequency of the impelling energy and in wide variations of frequency the func- tioning of various types of equipment is seriously interfered with. While variation in frequency is not nearly so common as fluctuations in voltage, a number of cases have been found where the correct operation of equipment has been affected by abnormal frequencies. The accuracy of watt hour meters is not seriously affected so long as the frequency remains within commercial limits but tests show that it is appreciably affected when the variation is excessive. Construction and Maintenance In the broad sense, as defined above, service may be considered to include the construction and maintenance of lines and equipment. Hazard to life and property follow from equip- ment that is poorly designed, constructed or maintained, and lack of attention to the proper care of lines, apparatus or equipment or other facilities will sooner or later be reflected in the quality of service. Poorly constructed or maintained electric lines are certain to cause interruptions or unsatis- factory voltage regulation. Poor telephone lines seriously im- pair telephonic transmission or prevent it entirely. Lack of proper maintenance of gas distribution systems causes stoppages and failure to give close attention to repairs on railway equipment is certain to affect the reliability of serv- ice :> * 13 There is a direct and positive relation between con- struction and service* Systems constructed in order to decrease investment at the expense of stability may give reasonably good service for a time or while favorable conditions of weather prevail. As the load increases and the equipment becomes in- adequate for the demand, service is impaired. During sleet or wind storms, and especially during electrical storms, service is very likely to be interrupted unless proper provisions have been made at the time of original construction. Precaution against hazard to the public is an obligation each electric utility owes to its community. Danger from broken poles or wires, low voltage circuits crossed with circuits of higher voltage, or defective equipment which may impose high voltages on secondary circuits, are all too common. Poorly constructed systems require excessive maintenance, and a saving in original investment which results in excessively high maintenance cer- tainly is not good judgment. The importance of proper construction and careful at- tention to maintenance are of primary importance in every branch of the public utility industry. Quality of Gas Four factors vitally related to gas service, and very largely affecting the safety, efficiency, cleanliness and con- venience of the use of gas are (1) heating value, (2) pressure, (3) amount of air required for efficiency combustion, and (4) sulphur content. It is not only important that the heating value of - , , ^ • , t , . . ■ V , . t , - 14 gas be of such value as to provide the required heat units per cubic foot, but it is also essential that the quality be uniform. Wide fluctuations in heating value are perhaps more annoying than low heating value of a uniform quality. Tests of the heating value should be made at points which will insure results repre- sentative of the quality of gas actually delivered to the users. Tests made at the manufacturing works are of great value from an operating point of view, but they do not serve to detect de- ficiency in quality which result in loss of heat content during transmission. Incorrect heats and improper operation during condensation may result in the production of a gas which loses heat giving constituents rapidly. In view of the varying con- ditions attendant upon the manufacturing and distribution of gas, together with the different degrees of condensation and loss in heating value that appear to prevail, the consumer is fully protected only if the tests are made at some point at a suffi- cient distance from the plant so that the results indicate a representative condition of the gas delivered to the ultimate consumer. Even if gas were uniformly manufactured at all times and in all communities the data available to show the probable loss in heating value due to transmission is yet too meager, I believe, to permit a definite determination of the heating value required at the manufacturing point in order to insure good service to the consumer. If tests at the works are to be used as a possible basis of control of operation it is desirable that they should be supplemented by tests made at some distance from the works from time to time in order to determine that the quality of the gas does not deteriorate unduly enroute 15 to the user. Many years ago the candle power standard practically determined the quality of gas to be furnished. This followed from the fact that it was used primarily for open flame lamps, and until a few years ago the candle power standard of gas was considered very important. There has recently come into use the British thermal unit standard and it is practically univer- sally accepted as the correct criterion of the value of gas to the consumer for both lighting and heating purposes, as the use of gas in open flat flame burners has largely fallen into dis- use. There is a surprising uniformity of mantle candle power per heat unit supplied per hour. Tests have been made which show a variation of less than three per cent from this rela- tion of candle power to heating value of the gas supplied per hour, over the interval 540 to 640 B,t.u. per cubic foot* It is important also to bear in mind the advantage to the gas maker of the heating standard over the candle power standard on account of the greater ease of operation to meet a heating unit standard as well as the smaller percentage loss in heat- ing value during pumping or distribution of the gas. In one series of tests reported to the Bureau of Standards it was found that pumping by-products gas, which had been "benzolized" to give about 16 candle power units in the open flame and 600 B.t.u. total heating value, produced losses of about 40 per cent in candle power and less than 7 per cent in heating value, due to compression and transmission at 30 pounds pressure for nine miles with the ground temperature less than 50 degrees Fahrenheit, On other gases mixed with carburetted water gas * 16 . with candle power value up to 22 and heating value up to 620 B.t.u. the candle power lost varied from 15 to 35 per cent, whereas the loss in heating value was not over 5 per cent and in some cases less than 2 per cent* In Circular No. 110 on the Influence of Quality of Gas and Other Factors on the Efficiency of Gas-Mantle Lamps, the Bureau of Standards concludes as follows: "With uniform gas quality and with good con- ditions of service in other particulars the useful- ness for mantle lighting of lean water gas of the qualities studied compared with rich water gas is slightly higher, for some types of lamps, than in proportion to the total heating values. Comparing lean coal gas and lean water gas of the qualities tested, the coal gas is slightly less useful, and this difference is about the same as the differ- ence between the two qualities of water gas. Hence, it may be concluded that the usefulness of a uniform quality of coal gas of 550 to 575 B.t.u. per cubic foot as compared with a uniform supply of richer water gas (e.g., one meeting a 22 candle- power requirement) is substantially in proportion to the heating values of the two gases. However, greater fluctuations in B.t.u. per cubic foot, slightly greater diff iculities in adjustment, and the other factors met in commercial use of lamps make the higher quality gas somewhat less desir- able per heat unit for general use than either of the two kinds of lean gas." The usual complaint of "poor gas" is ordinarily con- fused with poor pressure or improper regulation of appliances. Good pressure is perhaps even more essential than high heating value or uniform quality. Pressure conditions are easily de- termined by the use of a "U" tube or pressure gauge, and we have noticed that the utility which gives careful study to the kind of pressure prevailing throughout its system has less com- plaint of unsatisfactory service than the utility maintaining a better heating standard. Each utility should make pressure surveys at such intervals and of such comprehensiveness as may o ' ■ - / ' I 17 be necessary to keep itself fully informed regarding the char- acter of the service being furnished from its system* Variations in constituency of gas call for varying quantities of air to complete combustion* Obviously it is very important that gas using appliances give satisfactory operation at all times with no great amount of attention on the part of the consumer since the majority of consumers cannot be expected to adjust their appliances to meet any new condition of gas mix- ture, specific gravity of the gas, or others variable over which the consumer has no control* To a greater or less extent the users of gas on an industrial scale can and will make such ad- justments but the efficient utilization of gas for domestic purposes is ordinarily dependent upon such uniformity of supply as will permit satisfactory operation with a fixed adjustment of the appliances or fixtures* No objectionable feature of gas service is so quickly noticeable as the distribution of incompletely purged gas* Not only are foul gas fumes extremely obnoxious but they are des- tructive to animal and plant tissue* Tests for presence of hydrogen sulphide are very easily made but determinations of total sulphur content are not so simple* During the last year or two when the coal situation presented difficult operating problems, it was extremely difficult to purify the gas properly at all times • Proper size and rotation of purifying boxes and effective tests to determine when the oxide is spent, tend to reduce possibilities of sulphur trouble* Service of Water, Telephone, Heating and Railway Utilities A large number of the factors which go to constitute ■ •- - • - : . ‘ . « *: *: • ■ • ' ■ ‘ . , , ' :: i . a , • . , . . 18 . good service in electric or gas utilities are also common to water service. Such matters as continuity, pressure, con- struction and maintenance, meter accuracy, etc., apply to water service as well as to gas service or electric service. The quality of water, however, is even more important than quality of gas, although pressure is probably of less importance than gas pressure. Adequacy of fire service is a factor which is peculiar to water service. With telephone utilities the in- telligibility of transmission is of first importance, while the promptness of operators on first answer and on recall, their phraseology and courtesy, and accuracy of connection are phases of service depending primarily upon the personnel of the operators. Other phases of telephone service are dependent upon, and largely affected by, switchboard and station equip- ment and the construction and maintenance of lines. Utilities furnishing hot water service must pay special attention to the temperature and pressure of circulating water at all periods of day and night, and must be careful to furnish proper pres- sure throughout the system where steam heating service is fur- nished. In connection with service from steam and electric railroads and street railways, the reliability of service, adequacy of the equipment, safety to the public, sanitation of equipment and stations, and the furnishing of proper facili- ties and extensions are all factors which go to make the serv- ice. Handling Complaints It has been our experience that the method of handling 19 # complaints has been one of the most important, if not the most important, factor in molding the public opinion of public util- ities, The relations between the utility and the public are amicable or inimical, depending to a large extent on the util- ity’s success in satisfactorily handling complaints and the con- troversies arising through complaints* More than one municipal plant can be traced directly to the former utility’s failure to properly cope with some situations usually originating in some complaint against the service# Through the handling of com- plaints most utilities find their only opportunity of meeting their consumers. The utility gains its impression of its con- sumers through these complaints, which are often presented at a time when the consumer is indignant, and, on the other hand, the consumer gains his impression of the utility through the methods by which the complaint is handled# This is unfortunate, but it is a condition of fact which must be met and emphasizes the importance to a public utility of meeting the situation in a commendable manner# A consumer may have but one occasion in his experience to register a complaint against a public utility. His opinion of the utility - and certain of his associates will be influenced by his opinion - will be based on the treatment accorded him in that experience and the amount of individuality the utility’s representative injects into his case# To the complainant’s mind his case stands out as a particular case meriting individual attention# To the utility’s complaint man it is only one of dozens he has encountered, perhaps on the same day, and unless he is particularly adapted to the work and continuously on his I 20 guard he may treat the complainant indifferently, perhaps dis- courteously, and will dispose of the complaint in a routine manner very much as a local resident might answer inquiries of tourist visitors who are ever harassing him for information* To the complaint man it lacks individuality* To the complain- ant it is a real grievance and he will be permanently impressed by the manner in which it is handled* If the utility is will- ing to give each complaint a just investigation and impress the consumer with its sincerity of purpose the complainant is well satisfied, feels an appreciation of the utility* s willingness to properly serve, and to him the organization assumes human characteristics* He no longer thinks of it as a bloodless cor- poration. A satisfied consumer is a good advertiser. A dissatisfied consumer may cause a utility more trouble and grief than a whole community of indifferent custom- ers* If his grievance is not adjusted to his satisfaction, he is a cumulative liability. If his complaint, on the other hand, is handled to his satisfaction, he becomes a traveling asset and develops into a more effective booster for the company than if he had never had occasion to complain. We have seen munici- pal plants vigorously agitated in communities where the service is reasonably good, simply because the management, or some representative, with whom the consumer has had occasion to deal, has not shown the proper disposition to render the complainant the relief he desired. We can all recall individuals within our acquaintance who even in granting favors, make enemies* We also know of men who can refuse a favor and do it in such a manner as to make a warm friend of the man whose request was 21 denied. A complaint man with the right qualifications can make most of the dissatisfied consumers feel they have been given every courtesy and consideration or can cause them to see the un- fairness of their point of view, at the same time putting them in such a frame of mind that they will be satisfied with the treatment accorded them. Accuracy in Billing, etc . Utilities which are rendering service far above the average grade often bring upon themselves no end of trouble, the good will of the public leaves them and their ship of state is steered surely toward the rocks, by inaccuracies in billing resulting possibly from inaccuracies and irregularities in meter reading and errors in bookkeeping. An error leaves an impression that is a long time in correction. The public ex- pects the utility to be accurate in its work, probably expects the super-human of the utility representatives, and if an error is made unfavorable to the consumer, it is difficult to con- vince him that it was not an intentional move on the part of the utility to "gouge" him of his hard-earned money. Accuracy of Registration Electric energy and gas distributed by public utili- ties is in this age practically universally metered. Water service is furnished on both flat and metered bases. Accuracy of registration of electric, gas and water meters is necessarily extremely important since it is upon these devices that the company* s return depends and by them is determined the amount the consumer is to pay. Of these meters the electric meter is » « . . . , - - . - 22 most complex. Its accuracy is affected by voltage, frequency, amount of load and the power factor of the energy in the cir- cuit. The accuracy is affected by abnormal conditions, such as short circuits, lightning disturbances, vibration and rough handling. Gas and water meters are more rugged and their accu- racy not so likely to be affected, and yet the accuracy of a gas meter, for instance, is very appreciably affected by temperature conditions while impurities in water ultimately affect the accu- racy of water meters. Notwithstanding all this, the accuracy of these instruments is exceptional and the more experienced an individual becomes with a meter, the more dependence he seems willing to place in it. The general tendency of all meters that have been in service some time is to run slow, although occasional instances can always be found where meters over- register, sometimes excessively. The best studies of tests of electric, gas and water meters indicates that periodic tests should be made on electric meters at intervals ranging possibly from two and one-half to four years, at intervals of five to seven years for gas meters, and at intervals up to ten years for water meters. The fre- quency of all tests on all kinds of meters should depend some- what upon the amount of revenue derived from the particular in- stallation which is in general more or less governed by the size of the meter. The Public Utilities Commission of Illinois has seen fit during the last year to extend from two and one- half to four years the intervals of tests on all small alter- nating current meters which meet the requirements of the National Electric Light Code. The results of thousands of * . . ' " . . . . - - , • ‘ , 23 tests on gas meters made by one large gas utility in the country during the past few years appears to indicate that the accuracy of gas meters is retained very well until the meter has been in service between seven and eight years, after which time the tendency to under-register becomes marked* The Public Utili- ties Commission of Illinois has extended the interval on gas meters from five to seven years. The question is often raised whether meters register accurately on varying voltage or whether an electric light will consume more electricity if turned off and on repeatedly In- stead of burning steadily, A large number of electric con- sumers have been found under the impression that meters show no decrease In registration when voltage is low. With a view of determining accuracy of watthour meters at different voltages, we have carefully conducted a test, results of which are plotted on Plate III, from which it appears that watthour meters register slightly in error when voltages above or below normal are impressed. The curve referred to shows results of tests made on a Sangamo type W H" meter. Within commercial ranges of voltage (10 per cent above or below normal) the error has been found to be less than one-half per cent. It is interesting also to note that the meter over-registers slightly where the voltage is below normal and under-registers where the voltage is above normal, a condition probably contrary to what would occur to us on first thought as being logical. The character- istic curves of the Sangamo watthour meter as shown on Plate IV show that except for very light loads (below 8 per cent of normal) the meters are slightly fast for voltages below normal . ' * , . " - - i 24 . and slow for voltages above normal, the amount of error depend- ing on the load. This must not be taken to mean that meters reg- ister more energy when the voltage is low. The reverse is true. Registration is practically proportional to voltage, for con- stant current, but if the voltage is 90 per cent of normal the registration will be about 90.3 per cent of normal; that is, the meter will register about 0.3 per cent more energy than is actually consumed. To determine the effect of varying voltages on watt- hour meters we recently conducted a test where the accuracy of three meters of entirely different type and construction were compared. The voltage was suddenly changed from 0 to normal many times during the test. The results appear to show that the effect was to introduce no error greater than about 1 per cent. This is of course a very extreme condition and conclusively shows that variations of voltage within commercial ranges have no appreciable effect on electric meter accuracy. Other tests show that no appreciable error was introduced when the current was varied continuously from 0 to normal. Records, Tests, Surveys, etc . There are a large number of matters not directly af- fecting the consumer which are of vital importance in our opin- ion in the proper conduct of a public utility business. Rec- ords, tests, surveys, etc., upon which establishment of ade- quate service is based, are matters which the utility cannot af- ford to neglect. It has been our experience that in numerous cases public utility representatives have stated, and honestly,. . , . ' , . , , , , , , , 25 believe - that they have had no interruptions to service. It may even be that their representative consumers, provided the public attitude is favorable, may not recollect discontinuity. A re- view of records conscientiously and accurately kept will reveal the fact, however, that interruptions have occurred. The advan- tage of a record in such a case is obvious. A short outage now and then, especially at a time when it least inconveniences the consumer, is likely to be forgotten readily. Several such in- terruptions, however, if recorded and made proper use of, will impress the management with the necessity of giving attention to these matters of service. Voltage or pressure surveys invariably reveal condi- tions more or less serious, the existence of which was perhaps not even suspected. Or it may be that the subordinate repre- sentatives of the utility may not pay proper attention to the eli- mination of unfavorable service conditions, which if brought to the attention of the general manager or other official through a study of records will be given immediate and serious considera- tion. The question of testing all kinds of meters has been given more or less consideration and efforts have been made dur- ing past years to demonstrate the financial importance of giving attention to the accurate registration of the meters. Such tests, however, are only partially effective if records, includ- ing monthly or annual summaries, are not kept. A tabulation which will show the general tendency of all of a utility* s meters to under-register will be given the consideration it deserves by a well managed organization. The tester himself, or perhaps his 26 immediate superior, will not be impressed with the importance of establishing the accuracy of meters in the aggregate; his time is too much taken up with the routine of his work. It may be true that some old over-organized public utilities where some representatives have a hobby of developing forms and creating, rather than eliminating, office routine, will be burdening the utility with many excess, and perhaps duplicate, records. The reverse, however, is generally true, and it is safe to say that by far the larger proportion of public utilities suffer from lack of records rather than from a superfluity. In the Appendix are shown samples of suggested forms to be used in keeping records of interruptions, meters, meter tests, station operation, etc. 5 . * t 27 IV. REGULATION OF PUBLIC UTILITY SERVICE Development of the Public Utility Certainly one of the outstanding features of the economic development of the world has been the amazing widening of the public utility industry. The water utility supplies the greatest human necessity and has solved the problem of private and public sanitation. The street railway by facilitating travel has made possible the present large American city without the congested slums adjacent to factory districts. Gas and electric utilities have brought heat, light and power in every conceivable form to supply individual comfort and needs. Telephone and telegraphic systems have annihilated space, promoted the community welfare, and furnished the facilities whereby all parts of the civilized world are brought in almost immediate contact with each other. Inventive genius developed these ideas, courageous individuals promoted them and the public soon learned to give them its sup- port. Need for Regulation Contemporaneous with this movement have naturally develop- ed, as in any other enterprise, some of the abuses which have laid the industry open to criticism. Some of the utilities were formulated and exploited for speculative and unusual profit. This led to distrust. There was developed then, more or less by necessity, some sort of regulation to protect the public against abuses and exploitation. The carrying out of the obligations of the public service corporations created a necessity for a wiser , . * , - * , I * * . , 28 . system of regulation not only for the protection of the public but partly to protect the utility from the abuses of the public. The obligations of public service corporations are three- fold. First, they should furnish an adequate and sufficient service. Second, such service should be furnished at rates which are reasonable to all classes of consumers. Third, these cor- porations owe to the public from which their rights to operate are derived and from which must come funds for their construction, the obligation to treat it fairly in the issue of their securi- ties. First of all then there must be a set of standards for adequate service. A certain level of efficiency based upon the best resulting economies must be maintained. Thorough inspections and constant supervision must be carried out. The functioning of electric utilities has created a need for the establishment of maximum and minimum voltage limits assuring efficient use of the consumers* lamps, motors and ap- pliances. Meters should be periodically inspected and tested. Consumers should be given information as to the conditions under which their equipment can give the most efficient results. The requirements for gas service must be a heating value standard that will guarantee adequate cooking and lighting qualities. The pressure standard must be fixed and the amount of different constituents in the gas must be prescribed not only for the sake of service, but for the protection of life and property of the consumers. Telephone regulation involves the requirement of an adequate standard of service and elimination of unnecessary de- lays in answering calls and making connections. Regulation of water utilities covers such matters as adequacy of fire pressure. ' ■ , ' • : . . - f ' % * ’ , . * - » ' * 29 . sufficiency of pressure for domestic uses, purity of water supply, accuracy of meters and adequacy of the source of supply. Demands for extensions of gas and water mains and electric lines must be passed upon and the ability of a plant to earn a reasonable return has to be considered in connection with proposed extensions. Ex- pert theories of additional cost as against a basis for adequate return on the entire investment are problems too comprehensive to be delegated to local prejudiced and unqualified authorities. In the street railway field are many equal technical details to be taken into consideration when increase service, line extensions or rate changes are demanded. It is recognized further that the utility should not be allowed to exact more than a reasonable rate and the security must bear a proper relation to the property represented. There is an implied obligation on the part of the public that the investment devoted to the service under regula- tion shall be protected. For the just enforcement of these obligations some agency must be responsible. There can be no guess work or snap judgment or prejudice or political expression in regulation. The community and national Interests involved are too important to permit haphazard work. Regulation vs. Competition It was only natural that In the early periods of develop- ment a form of regulation was to be found in competition. The theory of competition as practiced in the utility business has been found unsound in that duplication of equipment and mainte- nance costs resulting therefrom have made it economically in- advisable to throw the field open to this form of regulation. There is still competition in telephone service in a good many ? : - i . - , - , ’ ♦ : aBsa a.d'j ■ jt- ■ ■■- " ■ ■■■- ■ - » ■■■ — ■ ■■ ■ ' ~~~ ' ■■ ~ ' ■ ■ .. ; 30 . localities. If regulation by a central body properly functions, there is no need for duplication as in competitive practice. Of all industries the telephone utility business has been recognized as standing foremost as a natural monopoly. We have all visited towns where two or three telephone systems have no physical con- nection. We have found it necessary to go to two or three differ- ent locations in order to talk directly to the parties in demand. The business man finds it necessary to pay for service from two or three different companies in order to secure the business of all the public. There was early recognized the monopolistic characteris- tics of the public utility enterprises and with the development of correct public thinking a demand arose for the establishment of some sort of regulation by properly selected bodies. It is only through the encouragement and protection of just and reason- able laws, rules and regulations established through the instru- mentalities of unbiased bodies of experts that the public utility industry has been stabilized and the utilities made recipients of a large amount of the capital of the people. Millions of people in the United States directly or indirectly have interest in public utility securities. This capital attracted by the recog- nized stability of the industry has made possible the provision of public utility service in almost every city and village in the United States and has brought the telephone and electric facili- ties into a large number of rural communities. These investments should be safeguarded. It Is in the interest of the utilities, and of the public as well, that provision for any class of public utility service be confined to one agent. It makes for economy. , - , ; , - - '• " . , * * ’ ' : 31 It is also in the interest of the utilities and the public that the regulation employed be such as to attract capital and make for the most efficient and economical use of the facilities em- ployed. Source of Regulatory Power I assume therefore that there will be no argument against the statement that there must be somewhere vested the authority and ability to solve the intricate problems of public utilities to the end that the shortcomings may be discovered and the cor- rect remedies applied. The authority to regulate public service enterprises has always rested in sovereignty, which means under our form of government that whatever power is or may be exercised by a city, village or town over public service corporations must be specifically granted to it by the Legislature. Exercise of any regulatory power by the State then cannot operate to deprive cities, villages or towns of a power v/hich they never possessed. The Supreme Court itself has repeatedly answered the question of the right of a state to delegate to such authority as it chooses the right to administer the affairs of the state. The following Supreme Court opinion is typical of those frequently expressed by that body: "Over all public and governmental powers exercised by the municipal corporation, the cor- poration acts as the agent of the State and the State is essentially supreme." State vs. Local Regulation The treatment of this subject necessarily centers around the question of the relative merits of state or centralized regulation and local regulation. Sincere opposition to state ■ . • )■ l ' • , ’ . • ' ~ ■ . 32 . regulation is entitled to a respectful hearing and fair treatment as is a sincere defense of it. Probably the most severe indict- ment of state or centralized regulation of public utilities as voiced by its opponents may be summed up in the statement, "State regulation is wrong in principle because it deprives the cities, villages and towns of the right and power to administer certain of their own local affairs and thus tends to destroy civic pride and responsibility." An analysis of any comprehensive study reveals the fact that cities seek to enforce obsolete and impossible franchise terms, and yet in the face of this we find cities making un- reasonable demands that the State in its regulation of public utilities require that franchise requirements be held inviolate. It is a matter of common information that operation under fran- chises keeps utilities in local politics, and we believe that the demand for local regulation now being made by certain ele- ments is an outgrowth of public misunderstanding. Municipali- ties are in no position to regulate issuances of securities and certainly in no position to attempt regulation of those utilities extending their fields outside the municipal limits, which in this era is undoubtedly true of a large percentage of the total. Cities encourage wasteful competition between utility companies. The utility regulation is not deemed a function of local govern- ment and it has been demonstrated beyond all reasonable doubt that cities are unable to carry on work now performed by State commissions, nor are they able to bear the expense of efficient utility regulation even if they were competent to conduct the work. Should the State choose then to leave in the hands of the municipalities the question of regulation of rates and service of ■ . - - - - ’ - . , 33 public utilities, it is the usual condition of affairs that the city could not afford the expense of a body equipped and qualified to intelligently determine the reasonableness of a rate or quality of service and establish standards therefor# When analyzed in every detail we are unable to cite any clear outstanding reason why public utilities should be locally controlled, and we believe that the political demands for such local regulations appeal pri- marily to the selfish motives. Utilities rapidly outgrew the condition of being local ser- vants • Telephone lines extended from state to state, coast to coast, and throughout rural communities. Even the local lines emanating from the exchanges in the towns or cities served sub- scribers outside the corporate limits as well as inside. Electric and gas central station plants began serving many communities from one large plant- often as many as one to two hundred. Transporta- tion systems ran outside cities; in fact, most of the business was often conducted between municipalities, leaving but a small amount of the business to be conducted within the city. Persons living within a radius of one hundred miles or more of a central station might be affected by its services, and rebelled against accepting regulation provided by municipal authorities of the town or city where the central plant might happen to be located. A state-wide interest, not a local one, immediately came into exist- ence. Cities and villages found that if they were individually to attempt regulation of rates and service, each would have to create commissions of highly skilled experts, and that there would probably be continuous conflict between the commissions of the various municipalities. It would still leave the utility without , . , , * , . . . . . - . . 34 regulation outside the city limits. That the state acting for all the cities and for all its citizens having voting power is better situated to undertake such regulation than the cities act- ing independently is no longer open to serious consideration. Home Rule When so empowered by the Legislature a municipality may, of course, undertake local regulation. It may provide regulations in its franchise, it may regulate by ordinance or pass new ordi- nances as the occasion demands to meet new situations. It may create a local board or commission. As we have already seen, however, any one of these methods would be incompetent to cope with the situation where the system extends beyond the municipal limits . The law has established protection to property and it is a narrow minded assumption to consider that a question of rates or quality of service can be determined by anybody at any time. Facts, not guess work, must govern regulation. If a local com- mission or a common council that has been given the power to do so should fix a rate for a public service corporation, it must be able to prove in court that the rate fixed is reasonable. The Home Rule exponent is too often mistaken in his impression of what constitutes liberty of action. Does he think that privileges granted him by virtue of citizenship in a free coun- try are curtailed because he, as a member of a city council, can- not dictate that the local utility shall furnish transportation for five cents, electricity for seven cents a kw-hr., or gas at eighty cents per thousand cubic feet? Without pausing to comment on the legal right of a State to delegate through its legislators * , . » : ' - . £ . * • • . . , . 35 to an organization of expert engineers and accountants, let us deal merely with the business aspect of the problem and note the fal- lacy of the theory or belief that a public good is done by reduc- ing a public utility's rates below that necessary to give a return which will attract capital and permit the business to prosper, A quotation from the United States Supreme Court is here pertinent: "Our social system rests largely upon the sanctity of private property; and that state or community which seeks to invade it will soon dis- cover the error in the diaster that follows. The slight gain to the consumer which he would obtain from a reduction in the rates charged by public service corporations is as nothing compared with his share in the ruin which would be brought about by denying to private property its just reward, thus unsettling values and destroying confidence." Assume, however, that a municipality possessed an unlimit- ed right to reduce rates and no redress were possible in court. The abuse of such practice would soon demoralize the industry and break the back bone of its business in the community. The local utility's business is not, can not be, foreign to us. Consider the innumerable benefits it brings to us which we could not pos- sibly enjoy, and without which our home nurtured businesses would not find it possible to compete with the world. An illuminating engineer has recently said: "A well lighted city will stabilize business, increase the value of real estate, reduce crime, and bring in more people as visitors, investors and buyers of the town's product." He might have added that without electric power industries could never be attracted to a city. Without it we cannot live as a cog in the machinery of industry. We are living and working not alone for ourselves but also for those who are, and are to become, our own, and for all others in so far as their interests and their welfare are common with ours or affected by - . ' . * * - * . • « • , * * * \ i 36 * ours* W © must not lose sight of the fact that our individual wel- fare is so related to the welfare of the aggregate that we can not but heap injury upon ourselves by stimulating agitation against any branch of industry with a view or effect of dwarfing it. This is especially true of public utilities. Not to mention the direct financial effect on the holders of public utilities' stock and se- curities, there is a broader effect, and a very vital one, upon the welfare of the community in which we live. A further damage to our business or that of our neighbor merchant or manufacturer would be caused by discouraging extensions or preventing develop- ment of the sources of those public utility commodities upon which the welfare of our community, of the State, or of the Nation depends. This is the true phi li sophy by which those who are sane and intelligent and conscientious are guided. Upon such philisophy are based all economies, all developments and all pru- dent action. Invalidity of Ordinance Contracts There seems to be prevalent throughout the state, especial- ly at this time, an impression that if given Home Rule city au- thorities can make rates that will be binding, whereas the funda- mental principle of the constitution has established the fact that the courts will give relief where it is necessary. Home Rule means nothing in making firm and stable rates for any speci- fied period if conditions warrant a change in those rates. It is the contention of certain city authorities that rates should be fixed in accordance with franchise ordinances and that these rates should exist without change during the life of the ordi- nance. Even though the proper authority were delegated to the - 37 cities by the state, no community could fix a franchise rate that could not be changed when conditions warrant. It has been repeatedly held by the Public Utilities Commis- sion of Illinois that under the Public Utilities Act the Commission has power over rates and service of public utilities regardless of provisions contained in ordinances or contracts. The case of the City of Chicago, et al, appelle, vs. Wm. L. O’Connell, et al, grew out of an order entered by this Commission relative to service of street cars operated by the Chicago City Railway Company and the Chicago Railway Company in the city of Chicago. In passing on this matter the Supreme Court held: "The regulation of public utilities is one phase of the exercise of the police power of the State. The police power may be exercised by the Legislature directly, or it may be exercised in- directly by conferring the power on agencies created by the Legislature. The power is an at- tribute of soveriegnty and is primarily vested in the Legislature, which has the right to re- call at any time from the agency to which it has been delegated, and after being recalled to retain it or confer it upon some other agency of govern- ment. In the exercise of this power the State may interfere whenever the public interests demand such interference, and in this particular a large discretion is necessarily vested in the Legislature to determine not only what the interests of the public require, but what measures are necessary for the protection of such interests." A contract between a public utility and a consumer may be considered analogous to a contract ordinance. In the case of the Union Dry Goods Company v. Georgia Public Service Corporation the United States Supreme Court held: "It is settled that neither the * contract’ clause nor the ’due process* clause has the effect of overriding the power of the State to establish all regulations and are reasonably necessary to secure the health, safety, good order, comfort, or general welfare of the community; that this power » ■ . , - 1 , • * r * , . 38 can neither be abdicated nor bargained away, and is inalienable even by express grant; and that all contract and property rights are held subject to its fair exercise." We firmly believe that franchises, if enforced, would in the main cause more dissatisfaction due to the absurd and impos- sible provisions existing in most franchises than now exists on the part of municipalities on account of the alleged curtailment of municipal privileges. State Regulation It has therefore been recognized that the utility is charged with a public duty, and therefore should be regulated by the public, and that the public in turn owes a duty to the indus- try which is regulated. It is recognized that this regulation could not be secured and enforced without the creation of semi- judicial bodies clothed with the wide powers of investigation, composed of men having a judicial sense of fairness and employing men highly skilled and experienced in their line of technical or accounting work. So generally is this condition now understood that within the last fifteen years forty two states have created commissions with ample authority to protect both the public and the industries to the end that rates for the necessities of life supplied by these industries shall at all times be reasonable, free from discrimination and adjusted to yield a reasonable return on the fair value of the property. Purpose of Regulation The regulating body must first undertake to determine what is essential to good service, or, in other words, what the user of the commodity really needs, keeping in mind always that the . , * » . * , * . , 39 maximum service for each unit cost to the user is one of the first essentials in establishing standards. All of the items hereinbefore mentioned should be given consideration, the util- ities should be informed of the requirements, and facilities for determining quality of service provided by both the regulating body and the utilities. In general, the purpose of the regula- tion should be to insure (1) adequate and continuous supply at all times and for all parts of the territory served; (2) safety for the users of the commodity and for the general public; (3) proper maintenance of the producing plant and the distribution system; (4) intelligent conservation of national wealth in coal, oil, gas, and other natural resources of the country; and (5) fair return to the operating company. Establishment of Service Standards One of the first important duties of a body attempting regulation of service is the establishment of standards of serv- ice. The Illinois Public Utilities Commission Law contains the following provision: "The commission shall have power to ascertain, determine and fix for each kind of public utility suitable and convenient standard commercial units of service, product or commodity, which units shall be lawful units for the purpose of this act; to as- certain, determine and fix adequate and serviceable standards for the measurement of quantity, quality, pressure, initial voltage or other condition pertain- ing to the performing of its service or to the fur- nishing of its product or commodity by any public utility, and to prescribe reasonable regulations for examining, measuring and testing such service, pro- duct or commodity, and to establish reasonable rules, regulations, specifications and standards to secure the accuracy of all meters and appliances for examin- ing, measuring, or testing such service, product or commodity. " In 1914 the Public Utilities Commission of Illinois 40 established a set of rules and regulations establishing standards of service for gas and electric utilities and subsequently es- tablished standards for water and telephone utilities. From time to time consideration has been given to the need for making cer- tain changes and amendments in the requirements, and such modi- fications and additions have been made as the conditions appear to warrant. Inspections and Investigations A corps of specialized engineers was early organized and a system of inspection throughout the State instituted. Investi- gations are made upon complaint or upon the Commission^ own motion. They may be "special'' for determining whether the grade of service is commensurate with an established or proposed rate or may be "routine" to determine the general character of serv- ice and degree of compliance with the Commissions requirements. It is the function of the service inspector to make a study of the various subjects discussed hereinbefore and to ob- tain such thorough knowledge of each that he is able to assign a grade which will fairly represent the degree of perfection at- tained. He must examine voltage and pressure charts, look over the distribution system of an electric utility or examine maps to determine points where the gas or water pressure is likely to be low, and make a study of the pressure at such points. If it appears advisable he makes tests of the service without know- ledge of the utility. This is especially advisable if a fair idea is to be obtained of the average conditions prevailing when the voltage is hand regulated and it is also true, perhaps to a lesser extent, when a determination of the heating value of gas r - , ■ - ' - ' ^ ‘ . - - \ . ■ , . - 41 Is to be made. There is a human trait in each one of us which by nature calls upon us to put our best foot forward and to con- duct ourselves in such a manner as to make the best impression. For instance, if a utility representative is aware that an in- spector is making tests of the system voltage, it would be only human for him to put forth a little more effort to see that bet- ter conditions of voltage prevail. The investigator should interview city authorities and representative consumers. There are often feelings of dissatis- faction on account of action taken by the utility which may not be revealed through an examination of the utility’s records or by an inspection of its service. It may have to do with conduct of the utility in matters which could not possibly come to the attention of an inspector. Inspections are made of the records to determine the quality and progress of the meter testing and some tests are possibly supervised. In case telephone service is being investigated, a number of calls are made with a view of determining the promptness of operators, their phraseology, and the accuracy of connection. Inspections may be made in a few hours or may require several days. It is usually necessary in order to get a fair idea of the service to continue the investi- gation through at least one peak period. Results not Methods to be Prescribed In the establishment of service standards the Commission is prescribing results and not methods by means of which the results are to be obtained. The Supreme Court has held that a commission has no authority to interfere with the broad dis- cretionary powers of utilities in the conduct of the details of - , - , , , . . . , . , , ■* 42 their business, considering that that is a problem which is to be determined by the utility itself as it is to be the sole judge of the manner in which results are to be obtained. In accordance with the decision of the Supreme Court only the results to be accomplished by the companies may be prescrib- ed and the companies are permitted to bring about these results by any means which they may choose to employ# The operating engineer is generally in a much better position to determine the most economical methods of procedure than is the technical staff of the regulating body. There are exceptional cases in which the regulatory authorities find it necessary to overrule the choice of methods employed by the company. For instance, an electric utility may be required to maintain a standby plant, possibly under sufficient steam to operate the machinery if serv- ice from a transmission line is unsatisfactory or inadequate. It may be necessary to make occasional suggestions as to the methods rather than to order the specific procedure by which the improvement is to be effected. — N ’ ■ 1 ♦ : ' ■ : ‘ . ;• : 43 . V. DETERMINATION OF COMPARATIVE VALUE OF SERVICE Need for Service Rating In connection with our extensive study of service matters throughout the State, we have seen a need for comparing gas and electric service in various communities. The necessity for such development arose out of the fact that it was difficult, practically impossible, to state specifically in any manner how the service of one utility or in one town compared with that in another community although there appeared a need for such com- parison. In one town the continuity may be good and voltage regulation poor. In the community with which comparison is desired the voltage regulation may be good and the continuity of service unsatisfactory. In many respects the service In one might be better than that in the other, while in other respects the service in the other may be better than in the first. In the absence of some form of abstract grading we have not been able to answer intelligently an inquiry as to the relative standing from the service point of view of two utilities. It was therefore found necessary, if comparison was to be made, to develop a method that would give some means of determining the relative grade of service in the two. It has been the usual practice of inspectors employed by regulatory bodies to report a rule either as violated or as complied with. This must necessarily be true. For instance, if a few meter tests are overdue, technically speaking, the rule is violated and must be reported as such. The result is. 44 a large number of rules may be reported as violated when the service is truly good. The number of rules violated does not, therefore, fairly indicate the character of service rendered. Frequent interruptions of service is a violation of one of the rules as is failure to properly record two runs during a meter test. But obviously the first far outweighs the other in im- portance. Actual conditions of service are manifestly much more important than are the records indicating the conditions of service, and yet either may violate a rule. In other words, it is a violation of a rule if the continuity of service is un- satisfactory. It is also a violation of a rule to keep no rec- ord of interruptions, although the interruptions may be exceed- ingly rare. One violation is more serious however, and the utility should not be given the same amount of discredit or criticism. Grading of Service The plan as developed and shown hereinafter in detail shows at a glance the degree of perfection attained in each phase of service as each is given a grade. To take care of the relative greater importance of one over the other, the grade as assigned by the engineer is multiplied by a given weight, the value of which depends on the importance of the factor. For instance, a constant of 30 is given where continuity of service is graded, whereas 5 has been chosen for use where records are considered. The total of the weights is 100, so that the var- ious grades may be multiplied by the respective constants and the products added. The final result so obtained is divided by 100 to give the resultant grade of service. It would seem upon first . * , . . , - . . * 45 thought that an adequate method could not be devised on account of the large number of varying conditions and the different opinions of inspectors. It is a matter of common knowledge, however, that grading systems upon which dependence is placed are used in schools and colleges, although the course of study may be entirely different and taken under different instructors. Did we not know that grading systems are in use we might say that a grading system could not be satisfactorily used in edu- cational institutions. Of course, no grading system can be devised except it be dependent, more or less, upon the judgment of certain individuals and upon approximations, but the method herein explained has worked very satisfactorily. The forms used in grading gas and electric service are re- produced below. They are stenciled on the back of the routine inspection sheets (see Plates V and VI) and the grading is done by the engineer making the investigation. The grades are checked against the report to insure uniformity of opinion. This checking is done by some one other than the engineer mak- ing the investigation. The forms show the items that are taken into consideration and the relative weights assigned. Grades have been assumed for the various factors and the grad- ing carried out to illustrate the manner in which the form is filled out at the time of the inspection. 46 The following form is used in grading service of gas utilities .

In order to insure uniformity of opinion and so far as possible to eliminate the element of personal judgment, the fol- lowing instructions have been prepared for use in grading serv- ice of electric utilities. Continuity of Service Few short interruptions, at time when least serious, deduct 0 to 3^ Few long interruptions, at time when least serious, deduct 5$ Few short interruptions, at time when most serious, deduct 10$ Few long interruptions, at time when most serious, deduct 20$ Many short interruptions, at time when least serious, deduct 20$ Many long interruptions, at time when least serious, deduct 30$ Many short interruptions, at time when most serious, deduct 40 to 50$ Many long interruptions, at time when most serious, deduct 50 to 75$ For failure to notify Commission of inter- ruptions , deduct 15$ For failure to notify consumers of contem- plated interruptions, deduct .. 10$ Note: If no records of interruptions are kept, give not more than 90$ Voltage Regulation To determine reduction in grade where voltage regulation for lighting purposes is unsatisfactory, multiply per cent of total consumers affected by 1 to 5, depending on degree and fre- quency of violation. Use the following constants where daily variation is beyond limits allowable for lighting service. If 1-5 per cent outside limits, use constant 1 If 6 -10 " " " " " " 2 If 11 -15 " " " " » » 3 If 16 -20 " " " " " " 4 If 21 -25 " " " " ” " 5 49 To determine reduction where voltage variation for power purposes is unsatisfactory, multiply the per cent of total con- sumers (lighting and power) affected by 2 to 10, depending on seriousness of violation. Note: If no records of results of utility* s sur- vey are available, give not more than .... 90$ Handling of Complaints Grading on this is to cover courtesy of employees, prompt- ness and efficiency in disposing of complaints, success in sat- isfying complainants, and is determined by judgment of the in- spector. Note: If no records of complaints are kept, give not more than 90$ Meter Testing a. If initial tests are not made, deduct 10$ b. If installation tests are overdue (depend- ing on per cent of tests, and length of time, overdue), deduct 1 to 20$ c. If periodic tests are overdue, deduct 1 to 4 per cent for each per cent of meters over- due in accordance with the following: If 1 to 6 months overdue, deduct 1$ " 7 to 12 ** " " 2$ ” 13 to 18 " " " 3$ " 19 to 24 " " " 4$ d. If proper testing facilities and equipment are not provided and checked (depending on seriousness of violation)deduct 1 to 15$ e. If testing is not done in accordance with standard practice, or where proper methods are not employed, deduct 1 to 20$ f. If request tests are not willingly and pro- perly made, deduct 10$ 50 Not©: If initial tests only are made, allow not more than 10$ If Installation tests only are made, al- low not more than 20$ If periodic tests only are made, allow not more than 70$ Construction and Maintenance Grade to be based on condition of plant and lines. De- gree of compliance with standard construction requirements, character of maintenance, possible hazard, and probability of impaired service are to be considered.

If duplicate records are not kept in the local office, deduct 15$ Merits of Grading System One of the important advantages of this development is that anyone may readily determine from the grading report the relative condition of each feature of the service, and tell whether it is good, medium or poor, A study of the routine inspection forms for gas and electric service (see Plates V. and VI) shows that the engineer’s report indicates the rules violated and the manner in which they are violated. The grad- ing which is given on a form stenciled on the back of the routine inspection sheet shows at a glance the degree to which compliance has been effected, A grade of 90 or 95 will indi- cate that a rule has been violated but only slightly so, where- as a grade of 30 would indicate a flagrant violation. From the point of view of a large public utility operat- ing in several towns there is an advantage in being able to show the average grade of service in all the towns on the sys- tem compared with towns on some other system, and the relative 56 status from a service viewpoint of the different towns on the same system. Such a method of grading continued over a period of years would give the regulatory body a means of comparing the general condition of service between periods. For instance, the average grade by months might be plotted over a period of years, and thus indicate the gradual decline or improvement in the service from one period to another. Were such data available for several years past one might expect a curve plotted from it to rise from January 1, 1914 until probably 1917, when it would show a decline until the latter part of 1920, when it would again begin to rise. Such information would have an important statistical value. It is believed further, and this has been demonstrated by the use already made of the grading, that a rating of the differ- ent towns in the matter of service tends to create a rivalry among local managers of the same utility and between different utilities, each striving to maintain an average above that of the other. Excellent opportunity is presented for impressing local managers with the importance of attention to the various details that enter into the furnishing of service, and this is especially true where the facilities and conditions under which the work has to be done are about the same. We find that as utilities become acquainted with the system they have a much better con- ception of the value of the various factors entering into service and are impressed with the importance of giving them attention. They have also a better understanding of the Commissions work- ings and become more familiar with the Commission’s requirements. It is expected that inspections would be made less fre- quently in towns where the grade shows a satisfactory service * * 4 • < * , ■ -< - * - - V. ' ' ; ‘ 57 while the interval between inspections would be shortened in com- munities where the service was found relatively poor. Influence of Local Management on Service Service is admittedly dependent upon management, the de- gree of influence depending upon the power and authority resting in the manager* s hands. Where the service in a community is furnished from a transmission line of a large system it may be argued that the character of service is beyond the control of the local manager. The table given below furnishes interesting figures, representing the extent to which the grade of service may be influenced by the local management. This is, of course, only approximate and is based upon an assumption of the extent to Which the local man has authority in certain service matters. It has been compiled upon the assumption that meter testing and voltage surveys are under the supervision of the central office, over which the local manager has very little, if any, control. It is also based upon the assumption that the authentic records of interruptions must come for the load dispatcher of the sys- tem, and for that reason a record of local interruptions only originates with the local manager. The compilation shows that even under these conditions the local manager may influence the grade received for electric service by 41.25 per cent when the grading is done on the basis outlined above. , 3 , . * ’ ' t ~ . rr • * * 58 Phase of Service Weight Contribution of Local Manager Possible Influence on Final Grade Continuity of Service 30 25 % of Grade 7.50 Voltage Regulation 15 75 % u tt 11.25 Handling of Complaints 10 100 % it it 10.00 Meter Testing 5 10 % it it .50 Construction and Maintenance 5 25 % it it 1.25 Adequacy of Capacity Provisions for Emer- gency 5 0 % If it .00 Adjustment of Bills Information on Bills Extension Policy Furnishing New Serv- ice 5 4 : 0 % If it 2.00 Consumer's Attitude 5 25 % If it 1.25 Record of Interrup- tions 5 50 % It it 2.50 Voltage Surveys and Records 5 0 % If it .00 Record of Meters and Tests 5 0 % It tt .00 Record of Complaints 5 100 % It it 5.00 < 41.25 -* . *• ■ ■ 59 APPENDIX PLATE I.
