Sayreville Power Plant
Sayreville Generating Station was constructed in 1930. It came online in October 1930 with two 30,000-kw units with a planned expansion to 180,000-kw generation. The original turbines operated at 450psi and 700°F. Its building expansion was completed in 1942, but installation of the generators and associated equipment was interrupted by the United States’ entrance into WWII. This expansion eventually came and brought the plant’s maximum capacity up to 100,000-kw. In 1955, it received an expansion for an additional 125,000-kw, increasing the maximum steam pressure to over 2,000psi at 1,050°F at the cost of $25,000,000.

Details on Sayreville Generating Station in more recent years become scarce but based on the limited information I can find it seems that following WWII, this plant received several additional generating unit upgrades at 125MW each, thus the plant would have been generating at least 350MW by the time it was decommissioned in the early 2000’s. It is currently being demolished.
