Photograph. Black and white photo showing an interior view of the turbine room at the Detroit Edison St. Clair electric power plant. The elevated view looks across the top of the turbine electrical generating unit that is located inside a long 2-story building. A typewritten note attached to the photo shows "Detroit Edison's newest steam turbine-generator, dedicated Friday, April 18, as the seventh unit at St. Clair Power Plant, is the 18th major addition to the company's power plant since the end of World War II. The new 143-foot-long machine, capable of producing 527,000 kilowatts, has increased the plant's capacity to 1,850,000 kilowatts, enough electrical energy to supply a community of about two million people. Unit No. 7 at the St. Clair Plant and a steam turbine-generator of similar size at the Trenton Channel Power Plant, are the largest generators now in operation on the Edison system.
