The parcel of land on which the six historic one- or two-story structures rested occupied 4.7 acres (1.9 ha) of a larger property owned by PGE.

Major equipment in these buildings in 1985 included an overhead crane, a turbine generator, electric switchgear, furnaces, conveyors, elevated walkways, concrete storage racks, boilers, and pipes.

[1] In 1892, to provide electricity for streetcars and lighting for a growing population, three Portland-area businessmen—Parker F. Morey, Henry Failing, and Frederick Van Voorhies Holman—formed PGE.

It was located near the Inman-Poulson Lumber Company, which supplied wood waste to fuel the station's steam boilers and which used electricity to run its machines.

Although Station L's boilers were converted to burn oil or natural gas instead of wood waste, its electricity became more expensive to produce than the hydroelectricity that PGE could buy from the Bonneville Power Administration.
