Prominent among the features of these substations are the switchboards of the company's design, well built, handsome in appearance and as safe as electrical apparatus can be made with every detail thoroughly worked out. Special attention is given to the back of the switchboards with respect to both the wiring and the provision for working space and also to the protection of cables leading from them. On the switchboard itself are installed the best operating devices procurable and every panel is laid out with a view toward simplicity of control, so essential to successful routine and emergency operation. Throughout the direct-current substations, with only a very few exceptions, all rotaries and their auxiliaries are counterparts, the principle type of rotary being the six-phase, diametrically connected, 500 or 1.000 kilowatt unit, with a three-phase, air-cooled transformer. These
rotaries operate from a 9.000-volt, 25-cycle transmission system, while current is delivered to the direct-current
system at 250 volts. The center of the low-tension side of the three-phase transformers furnishes a neutral connection to the system. The transformers are usually three-phase delta connected on the high-tension side and six-phase diametrically connected on the low-tension side; the parts being all in one case, with an ample opening in the bottom for air blast from below. The six-phase regulators are of the induction type remote controlled and provided with an open base for air blast. The rotaries are also installed in such a manner as to permit the upward passage of cooling air. The regulators used with the 500-kilowatt rotary installation-are of a capacity of 44 kilowatts, while those used with the 1.000 rotaries are of 88 kilowatt capacity. Copper bar usually furnishes a neat
and efficient means of connection between transformer and regulator and between regulator and rotary. All rotaries are equipped with speed limit devices, while reverse current attachments to the direct current ammeters open the circuit breakers of the rotaries upon a reversal of current. Some of the speed limit devices are those of the centrifugal type, while others are a purely electrical variety which operate upon increase of frequency. A few details of the standardized rotary and feeder panels serve to illustrate the general high standard of construction. On the rear of the board the bus construction is such that the positive and negative connections are kept entirely apart, the positive bus occupying the upper and the negative the lower half of the board. Copper bars connect the rotary cables to the buses, while small, well-ordered wires form a continuation of the multiple control cables from the terminal boards to the instruments or controlling apparatus. Thus all cables are kept off the back of the board, making it easily accessible. On the front of the switchboard uniformity in operation of switches and unmistakable indicating and signal devices furnish all that is necessary for reliable operation. Transmission lines are usually brought into the substations by different routes from different sections of the generating station. The high-tension bus at the substation is usually sectionalized so that immunity against a complete shut-down is obtained. This is further illustrated by the study of the individual installations, wherein the large proportion of storage batteries add their reserve strength to the bulwark against interruption of service. The installation of cranes, wherever there is revolving machinery and sufficient head room, is a valuable feature of these substations, which greatly facilitates the rapid installation or removal of apparatus in cases of emergency.
DOWNTOWN SUBSTATIONS:
In the "downtown," or most thickly built up, business district of the city, bounded on the north and west by
the river, on the east by the lake, on the south by 12th street, known to the company as District No. 1, six substations operate to maintain the three-wire, direct-current service, and since the varying load conditions here
affect all of these substations similarly, they will be considered together. The proportion between revolving machinery and battery installations is very carefully maintained, and a study of this district, regarding its load factor, its connected load, the time of the daily maximum and the amount of the maximum load, with respect to the system as a whole, could be made the subject of a most interesting treatise. One feature of similarity among the substations, all located on expensive real estate, is the fact that five of the six are located in basements of
office buildings. The one exception, the Market Street Substation, occupies the lower floors of a building owned by the Chicago Edison Company. The substations known as "Randolph Street", "Dearborn Street" and "Jackson Boulevard", the names in each case being derived from the streets upon which they are located, are equipped with rotaries only. The "Adams Street" and "Haddock Place" substations are equipped with batteries only, while the new "Market Street" Substation combines both equipments.
South Side Substations:
The old South Side of Chicago, known to the company as District No. 2, is bounded on the north by 12th street, on the east by Lake Michigan, on the south by 39th street and on the west by Armour avenue. Three substations supply this district with current for business and residence purposes. Their locations are such as to form the electrical vertebrae of this rather attenuated branch of the system. The maximum load in this district occurs somewhat later in the evening than that of District 1 and is, therefore, no additional strain on the machinery at the generating stations, upon which these substations are dependent, at the time of "Peak."
NORTH SIDE SUBSTATIONS
In the northern district of the City of Chicago, a territory of about two and one-half square miles, bounded on
the north by North avenue, on the east by Lake Michigan, on the south and west by the Chicago river, are four substations. The load in the eastern portion of this district is principally a lighting load, but in the western and particularly southwestern portion a heavy motor load is being developed. Submarine cables afford a tie between the direct current network of this district and that of District No. 1, just south of the river.
WEST SIDE SUBSTATIONS
The West Side, known officially as District No. 3, is the newest territory invaded by the Chicago Edison Company. Five years ago there was practically no business in this section of the city and to-day five substations are kept busy supplying the electrical needs of the district. This district, bounded on the north by North avenue, on the east by the Chicago river, on the south by 39th Street and on the west by Ashland avenue, covers an area of about four square miles, the Chicago river separating it from Districts 1, 2, and 4. Harrison Street Substation, which has already been referred to in the description of the generating station of the same name, due to its location on the north side of the plant, consists simply of two large batteries, each of 1.000-kilowatt capacity, at the one-hour rate. Its only piece of rotating machinery, a 100-kilowatt booster, enables its batteries to be charged. The rather distant location of this battery from the load centers of either District 1 or District 3 renders it serviceable for either district, and therefore it seemingly partakes more of the nature of a station reserve than a district battery.
Similarly the Market Street Substation, although located on the east side of the river and therefore in the downtown district, also supplies current to the three-wire system on the West Side. |

| THEMA | Edison Building |
| TEXT | By no means least in importance among the company's downtown properties is the handsome and substantial Edison Building, containing the General Offices of the company. The basement and rear portion of the first floor contain the Adams Street Substation. The site of the present building, 139 Adams street, marks the location of one of the company's earliest endeavors in the field of electric lighting, although nothing of that historic plant now remains.
The Edison Building, of moderate height and with large, towering office buildings on either side, presents the strong yet refined forms of the French Renaissance, and has a facade of strong individuality, commanding attention by its richness and beauty of detail, rather than by its bulk. This facade is of Milford pink granite, the surface for the first two stories being highly polished, while the upper portion to the top of the parapet wall is ten-cut work. Above this is a cresting and a large central motive of terra cotta, and, crowning all, a Mansard roof of red tile. The walls and ceiling of the entrance hall are of English vein Italian marble, and the floors of marble mosaic. The stairs to the second story are of marble, with a heavy wrought-iron balustrade. The executive offices of the company are located in the front portion of the building, on the fourth and fifth floors. The Directors' Room, on the fifth floor, is in Italian Renaissance style, with panels of mahogany wainscoting twelve feet high and coved ornamental stucco ceiling. A feature of the company's general office building is the Employes' Library and Meeting
Room, which is wainscoted five feet high in dark English Oak, with green walls above, and has a floor of quartered
oak. The entire building is occupied by the offices of the various departments of the company, among which might be mentioned the Contracting, Inspection and Construction Departments on the second floor, the Accounting Department on the fourth floor, the Purchasing and Supply Departments on the fifth floor, the Operating and Engineering Departments on the sixth floor, and various other departments located throughout the building, with particular reference to their co-operation with the foregoing and their work and relations with the public. |

| THEMA | Adams Street Substation |
| TEXT | The "Adams Street" Substation, located at the heart of the business district, ranks first by reason of its
seniority and the amount of output that it distributes. It was originally intended as a distributing center for
the direct-current generators at Harrison street, which office it has maintained through the epoch of modernizing
which the system has undergone. Current is supplied to the bus bars of the distributing switchboard by a trunk line from the Harrison Street Station, of a circular millage amounting to 63.000.000 c. m. and a length of
3.400 feet, and is distributed by means of feeders, 47 in number, and of sizes varying from 350.000 to 1.000.000 .m. Three batteries, averaging 154 cells per battery, with a united capacity of 27,000 amperes at 1/2-hour discharge rate, or 8,400 amperes at the 8-hour rate, have been installed in this substation, making a battery installation of unusually large size. A three-unit booster set with a 300-horse-power motor, driving two 100-kilowatt generators for charging the batteries, completes the equipment. |

| THEMA | Randolph Street Substation |
| TEXT | A 3.000-kilowatt substation in the basement of one of the city's largest office buildings, with headroom preventing the installation of any units larger than 500-kilowatts and with a single consumer, just across the street, having a connected load of 40.000 lamps and 3,000 horse-power in motors - such are the unusual conditions defining the Randolph Street Substation. Installed about three years ago, and containing at present five 500-kilowatt rotary converters, with a 100-kilowatt, 125-volt balancing set arranged to be thrown to either side of the three-wire system, this substation operates to maintain the service in the northeastern part of the downtown district. The plans admit of an increase to an ultimate capacity of 6,000 kilowatts in rotary converter units. |

| TEXT | While really a modern plant in every detail of equipment, this is the oldest of the company's downtown rotary substations. Like the Randolph Street Substation, it is installed in a basement, and it required a great deal of ingenuity to get all the desired apparatus in place. At present five 500-kilowatt rotary converters supply the central portion of District 1, this station being very centrally located. This substation was installed
about four years ago, and has reached its limit in capacity. |

| THEMA | Market Street Street Substation |
| TEXT | One of the most important, the most recently installed, and the finest in point of structural ensemble is the
Market Street Substation. This plant is located in the basement and on the first and second floors of a fine
eight-story steel building, which, with an imposing plate glass and stone front, makes the building by far the
handsomest structure in the vicinity. Four 1,000-kilowatt rotaries and a 1.200-kilowatt battery (one-hour rate of discharge) furnish current to the northwest part of the downtown district. Part of the output is also passed under the river, by tunnel, to the West Side. The high-tension switching installation is located in an air chamber in the roomy basement, which is also reserved for blowers, and cable connection to the old, previously described Washington Street Station. On a gallery above the main floor and directly over the rotary and feeder panel, a switchboard for the operation of the 4.500-kilowatt auxiliary steam plant in the adjoining building has been installed. Provision has been made for increasing the capacity and present arrangement to four 1.000-kilowatt converter units, two of which will have additional transformer and regulator capacity to give a range of 240-360 volts at the commutator, permitting their use for the charging of batteries without the intervention of boosters. |

| THEMA | Jackson Boulevard Substation |
| TEXT | This station occupies space in the basement of the magnificent new Railway Exchange Building on Jackson Boulevard, in the southeastern part of the downtown district. Here we have headroom permitting installation of 1.000-kilowatt units, two of which are now being installed. The ultimate arrangement contemplates six 1.000-kilowatt rotary converters with all accessories. Two 500-kilowatt units have been in service for about nine months in a temporary location during the construction of the building. The load conditions in the vicinity indicate that a rapid increase in the capacity of the substation will be necessary. The larger and more improved type of converter units with three-phase transformers lend themselves readily to the excellent arrangement of apparatus. A noteworthy feature of this installation is the provision for an air supply consisting of a large duct running under the floor of the basement and having its intake, which is provided with a filter, opening at the sidewalk. |

| THEMA | Haddock Place Substation |
| TEXT | This substation is installed in the extreme north-easterly section of the downtown district, near commission houses and a large number of elevator power consumers. It is connected by a heavy tie line to the bus bars of the Randolph Street Substation, about 800 feet distant. Two 1,000-kilowatt batteries (one-hour rate of discharge) and a 100-kilowatt, three-unit booster set comprise the electrical equipment of this substation. The first of these two storage batteries is notable in that it was installed in record-breaking time, the entire installation of battery, booster, switchboards and all underground connections in street ready for one-hour rate of discharge, covering a period of only 57 days, from the date on which expenditure was authorized and apparatus and material ordered. The battery proper was installed by the Electric Storage Battery Company of Philadelphia, and all other work by the company's own organization. |

| THEMA | State Street Substation |
| TEXT | Located just south of the northern boundary of District No. 2 on State street, near 12th street, is the State
Street Substation. Need for a substation in this locality was felt long before a location could be secured, for selection of a site was confined to a small radius. The immediate vicinity of the substation is developing rapidly
with a class of commercial buildings requiring a considerable amount of general power as well as elevator power
and lighting. This substation is notable in that it was erected on a 20-foot lot, which is rather narrow for substation purposes. However, the substation is a complete one, containing two 500-kilowatt rotary converters, one 275-kilowatt battery (one-hour rate of discharge), with a 30-kilowatt, 3-unit booster set, capable of use as a balancing set. The high-tension apparatus is located on a gallery in the front over the rotary room, the battery being located in the basement. Living rooms for the operator are provided above the rotary room. The building, though rather small, is made conspicuous by the striking contrast which its neat pressed brick front presents to the somewhat sordid surroundings. It is entirely of brick and steel construction, and is altogether a very attractive and interesting little substation. |

| THEMA | Twenty-First Street Substation |
| TEXT | Located about midway between the State Street Substation and the Twenty-seventh Street Substation is the Twenty-first Street Substation. This plant is installed on the site of an old generating plant, one part of the building being used as a storeroom, another as a substation. The load in this district is mixed business and residence lighting in its character. The substation contains two 500-kilowatt and one 250-kilowatt rotary converter, and is capable of extension considerably beyond this capacity, as a large amount of additional floor space is yet available in the old plant. |

| THEMA | Twenty-Seventh Street Substation |
| TEXT | Six years ago this plant was a generating center of the southern district of the Chicago Edison Company. It is located on Wabash avenue and 27th street, and about 2,5 miles distant from Harrison Street Station. Being in a residence district and without railway or river facilities, all coal has to be hauled by wagons. The engines are run non-condensing. The building is of brick and contains, at the front, living rooms for the engineer and a lamp exchange room for the district. In 1898 rotary converters began to creep in and fires began to be banked. The little central station became a dependency upon the Harrison Street Station. There remains, however, a generating plant of about 920-kilowatts capacity. Four Heine boilers, with a total of 1.700 horse-power, furnish steam for one 135-horse-power tandem compound and two 250-horse-power tandem compound McIntosh and Seymour engines, and one
vertical, cross-compound, 600-horse-power Ball & Wood engine. Belted to the first three mentioned are six 100-kilowatt Edison bi-polar shunt machines and to the last mentioned two 200-kilowatt General Electric multipolar, direct-current, 140-volt generators. One generator in each of these sets of two is connected on the positive and the other on the negative side of the three-wire system. This station, which has been in operation for 12 years, still does regular duty as a subsidiary steam plant. In the same building with the generating plant, and in reality in the engine room of the station, there are two 200-kilowatt and one 250-kilowatt rotary, also a 30-kilowatt, 3-unit booster set. At the north side of the station a 275-kilowatt battery occupies a separate room. The rotaries are all of the older type, as this was the first rotary converter installation of the Chicago Edison Company, they being started in service when the transmission line pressure was but 2,250 and later 4,500 volts. Some of these machines have been installed for six years, having been in continuous service during that time. In this substation were installed the first rotary converters ordered for lighting service in America. |

| THEMA | North Clark Street Substation |
| TEXT | On the north side of the city the Edison Company has one subsidiary steam plant, formerly known as the "Newberry Library Plant," a name derived from its proximity to the above-named building. The proximity in location is, in fact, almost identity, for the station appears to be a part of the same structure. This plant is rather small, but deceptive in appearance, for it is quite well filled with apparatus, there being both generators and rotary converters installed. In its history and present capacity it is very much like the Twenty-seventh Street Station, previously described. Twelve hundred and seventy-five horsepower in Heine boilers supply four vertical, cross-compound Lake Erie engines, one of one hundred and fifty horse-power and three of two hundred and twenty-five
horse-power each. To these engines are coupled two 50-kilowatt, 135-volt, direct-current generators and six
75-kilowatt, 135-volt, direct-current generators. These generators are balanced on the two sides of the three-wire system and are employed in their present capacity as "Peak" machinery. This is one of the few substations where there are to be found remnants of the original rotary converter installation, the company's first venture in converting apparatus and high-tension transmission. Two 100-kilowatt, 125-volt rotarles, one operating on each side of the three-wire system, also operating in parallel with the 250-volt, 500-kilowatt rotary, complete the substation
equipment. |

| THEMA | Sedgwick Street Substation |
| TEXT | On Sedgwick street, near North avenue, the northern boundary of the Edison Territory, there was erected about two years ago one of the company's typical modern substations - two buildings of fireproof construction, one in the rear of the lot, being a separate battery structure, while facing the street is the rotary converter building. This substation contains two 500-kilowatt rotaries at present, and a 425-kilowatt battery. A 30-kilowatt, 3-unit booster set furnishes a means of charging the battery from the system. In this station we find a high-tension gallery with the rotarles on the main floor. This type of substation is installed quite extensively by the company where building lots are of inconsiderable width. The installation of the battery in a separate building leaves the basement
of the rotary converter building free for the installation of air ducts and cable runs. |

| TEXT | The Northwestern Railway Company requires a large and unfailing source of electrical energy for operating air compressors which furnish compressed air for its signal system, as well as for lighting its passenger depot and terminal equipment and yards. For this purpose the Chicago Edison Company has installed in one of the Railway Company's buildings on'Kinzie street one 250-kilowatt and two 100-kilowatt rotaries of the older type. In addition to furnishing direct current for the air compressor motors and railway company's lighting, three feeders from this substation supply the Edison System in the vicinity. |

The building is of brick and steel, equipped with a crane, and the basement free for use as an air chamber and for cable runs. The second floor is occupied by a 600-kilowatt battery, while the main floor is planned for five 1.000-kilowatt rotaries, to be installed as the district develops. The present equipment consists of a 500-kilowatt rotary converter and a 30-kilowatt, 3-unit booster set. This substation also represents another phase in the development of the company's property, in that real estate of continually enhancing value is secured while still within reasonable cost, and a commercial building of such nature is erected on rear of lot as will fulfill present requirements, permit extension to front, and such additional stories, up to eight in height, as future rental requirements may make advisable. |

impracticable to maintain pressure here by feeders from existing stations. The building, a small brick structure on an alley, is located on a strip of land which permits of enlargement and more permanent structure should the necessity arise. The present equipment is two 100-kilowatt, 125-volt rotaries, operating on either side of the three-wire system, and one 500-kilowatt, 250-volt rotary installation. |

| THEMA | Lydia Street Substation |
| TEXT | About two years ago one rotary converter was hastily installed on the rear of a lot facing Lake street and extending through to Lydia street, near Union street. The load increased at such a rate that work on a large substation was soon begun. The present Lydia Street Substation, the result, is in some respects like the Market Street Substation, being located on expensive real estate. The foundation provides for a future seven-story building of brick and steel, with cut stone and plate glass front, only two floors of which have so far been built. The future upper floors, when erected, may be rented to outside tenants, since the basement and first floors only are occupied by the substation. In the basement there is a storage battery with a capacity of 1,000 kilowatts, on the first floor are two
1,000-kilowatt rotaries and above on a gallery is the high-tension equipment of line switches and buses, from
which leads are taken directly to the converter transformers on the first floor. A 100-kilowatt, 3-unit booster set, capable of use as a balancing set, on the three-wire system, completes the electrical equipment of this substation, which has come to be recognized as a most important one and bears much the same relation to District 3 as the Randolph Street Substation does to District 1. |

| THEMA | West Division Street Substation |
| TEXT | This substation is located on West Division street near Ashland avenue and is within one-half mile of the northwestern operating limit of the Edison Company; it bears the distinction of being the only combination station of the company, that is, a substation distributing both direct current and 60-cycle alternating current. The building
is of brick and steel, with a basement battery and a high-tension gallery above the rotary converter room. Living
rooms for the operator are provided on the upper floor of the substation, and the front of the lower floor is used
partly as a district supply office. This structure is of rather greater width than the average substation, being
50 feet wide and making a double equipment possible. Two 500-kilowatt motor generator sets, supplied with 25-cycle current, deliver 60-cyele alternating current to portions of the northern and of the western districts of the Commonwealth Electric Company. Two rotary converters, a 425-kilowatt battery and a 30-kilowatt, 3-unit booster set are at present also in operation here. Both rotary and motor generators are fed from common transmission lines. |

| THEMA | West Fourteenth Street Substation |
| TEXT | This substation was installed in a new brick and steel structure on 14th street near John street about three years ago. It supplies the southern part of District 3. The building faces the street and is of sufficient size to accommodate three 500-kilowatt rotary converter sets. Future extension to a capacity twice this amount is possible.
At present this station contains one 500-kilowatt rotary converter, one 250-kilowatt rotary and one 275-kilowatt
battery with two 15-kilowatt booster sets, an equipment ample for the present needs of this district. |
