Early Power Generation
|(1883)* - Banning Street Electrical Plant -- The first electric light plant in Los Angeles was built in 1882 by Charles L. Howland on the corner of Alameda and Banning Streets (In 1883, Howland and others formed the Los Angeles Electric Company).|
In 1831, Michael Faraday devised a machine that generated electricity from rotary motion, but it took almost 50 years for the technology to reach a commercially viable stage. In 1878, in the US, Thomas Edison developed and sold a commercially viable replacement for gas lighting and heating using locally generated and distributed direct current electricity.
The Edison plant supplied its light through incandescent lamps. In 1882, a similar kind of lighting, in an improved form, was proposed for Los Angeles by Charles L. Howland, representing a San Francisco based company, the California Electric Light Company (now PG&E). The name changed later that year to the Los Angeles Electric Company).
On September 11, 1882 the City Council unanimously voted to enter into a contract with Howland to “illuminate the streets of the city with electric light.” The contract called for Howland, at his own expense, to install seven 150-foot-high masts each carrying three electric lamps and to provide the distribution poles, lines, and the electrical energy needed to light them.
Howland set quickly to work. He had received a deadline of December 1, 1882 to have the masts erected and electricity on. By October 25, he had purchased a lot on the corner of Alameda and Banning Streets where he proceeded to put up a brick building, 50 by 80 feet, to house the boilers, engines and the 30kw, 9.6 ampere “Brush” arc lighting equipment for supplying the electric energy. Three weeks later, by November 16, the masts were in place and soon afterwards the pole lines and wires were strung along the streets leading to the masts.
The project was considered so successful that before the expiration of Holland’s two year contract, he and others had formed the Los Angeles Electric Company, which besides serving streetlights, supplied arc lights for commercial establishments.*^
Charles H. Howland also chartered the Los Angeles Electric Railway Company on September 11, 1886. It began operations on January 4, 1887 with the line opening from Pico Boulevard and Main Street traveling west to Harvard Boulevard. In 1896, many of the major horse and cable cars operating in Los Angeles converted to electrical power.
It should be noted that In addition to providing power for electric street lights, the early power plants mainly provided electricity for the new electric railways that were proliferating throughout the Southland.**^

Early Electric Light Generators (ca. 1895)
|(ca. 1895)^* - Photograph of a man operating electric light generators in Los Angeles, ca.1895. The generators are at center and are belt-driven by reciprocal steam engines. The belt can be seen at center and is connected to a gigantic metal wheel in the foreground at left. A man is standing in the background near the electric generators. The room in which the generators are housed has wooden floorboards and wooden walls. The electric generators have the words "DAFT ELECTRIC LIGHT” engraved on them.|

The two-story brick utility building stands next to a cleared lot in front of an unpaved road in which streetcar rails can be seen, surrounded by utility poles. Houses in the residential area of the city can be seen to the left and on the hills in the background. A horse-drawn cargo wagon makes its way down the street at left. Between 1896 and 1906 the power house was in use as Edison Electric Company Steam Plant Number One.|
Pacific Light and Power Company Power Plant (ca. 1912)
|Pacific Light and Power Company's first power plant (photo: ca. 1912). SCE would purchase Pacific Light and Power in 1917. In 1946 SCE constructed a power plant at the same site. Today a modified version of this new plant is owned and operated by AES.^|
|(ca. 1912)^ - This Pacific Light and Power Company power plant was built in 1902 to provide electricity for the Pacific Electric Red Car system in Los Angeles and the surrounding Redondo Beach area.|

Early LADWP Power Plants
San Francisquito Power Plant No. 1 (1917)
|(1917)* - The San Francisquito Power Plant No. 1 was placed in service in 1917 and energy was delivered to Los Angeles over a newly constructed 115 kV transmission line. This was the Los Angeles Bureau of Power and Light's first step in becoming an independent electricity provider.|
Construction of he San Francisquito Power Plant No. 1 began in 1911 at the same time the LA Aqueduct was being built (1907-1913).
In 1909 the Bureau of Los Angeles Aqueduct Power was created to build hydroelectric power plants along the Los Angeles Aqueduct. When Los Angeles acquired water rights in the Owens Valley section of Inyo County to construct the LA Aqueduct, it also obtained water-power sites along the way.
Ezra F. Scattergood was selected as the Bureau’s first chief electrical engineer. Scattergood led the way in the development of hydroelectric power along the route of the aqueduct and became Mulholland’s counterpart for the Power System.

River Power House (1917)
|(1917)** - Built in 1917, by the Bureau of Power and Light, the building was located in Studio City on Coldwater Canyon (originally Diaz Street) at the Los Angeles River. View on the left shows water passing through the turbine. City officials and River Power House are seen in the foreground. Water was channeled to the Los Angeles River and sent to the Buena Vista pumping plant in Elysian Park. From Elysian Park, the water could be sent to either east Los Angeles or to the Franklin Canyon Reservoir and then into the west side water system.**|

San Francisquito Power Plant No. 2 (1928)
Man standing by generators (1928)* - St. Francis Dam in San Francisquito Canyon near Saugus was completed in 1926 and failed in 1928. It was part of the Owens Valley Aqueduct System. This pre-failure photograph shows a man standing by 2 hydroelectric generators in Power Plant No. 2. The plant was destroyed when the St. Francis Dam failed on March 12, 1928. By November 1928, this plant was completely restored and back in service.

Built in 1924 for the former Los Angeles Gas & Electric Corporation, on a 14 acre tract near Ocean Ave and First Street, the Seal Beach Steam Generating Plant was acquired, along with the Alameda Steam Generating Plant, by the Department when it purchased the electric system of the Los Angeles Gas and Electric and took possession of the properties February 1, 1937. The Alameda Street plant was retired from service by Board resolution in 1951. The combined capacity of the two generators at the Seal Beach plant was 75,000 kilowatts.*^
|(ca. 1934)^^ - The original smokestack was damaged during the 1933 Long Beach Earthquake and replaced with a much shorter one as seen above. The Stanton House stands across from the plant on the right. The Seal Beach plant was taken out of service and demolished in 1967.|

Alameda Power Plant
|(1930s) - The Alameda Steam Generating Plant was acquired, along with the Seal Beach Steam Generating Plant, by the Department when it purchased the electric system of the Los Angeles Gas and Electric and took possession of the properties February 1, 1937. The Alameda Street plant was retired from service by Board resolution in 1951.|

Harbor Steam Plant (ca. 1942)
|(ca. 1942)* - Harbor Steam Plant Unit No. 1 construction. It is planned that the initial unit will be placed in operation about December 1942, at which time it is expected that present generation facilities will be inadequate for the winter peak. Construction of the plant actually was started early in 1932 and a few months later was halted by injection proceedings. The Bureau was successful in establishing its right to build the plant and the injection was dissolved, but later in the year an agreement was entered into for purchase of necessary energy and the steam plant construction program was postponed in favor of concentrating the Bureau’s efforts upon development and utilization of Boulder Dam power.*^

Completing an eight-year construction program that was started in April of 1941, suspended through the war years and delayed through many months of the postwar period by scarcity of materials, equipment and manpower, Unit No. 5 at the Department’s Harbor Steam Plant was placed in service and synchronized to the system on the afternoon of July 5.
