Power Plant #11 was originally constructed in 1914. The plans at the time called for the installation of two comparatiely small 3,500kva three-phase turbogenerators to start out with, but with sufficient additional infrastructure constructed onsite to permit an ultimate capacity of 100,000kw. It would eventually surpass that capacity, but by 1931, it was still only about a third of the way there as it was running three 13,000kw Westinghouse units (installed in 1914, 1918 and 1922, respectively). The 1931 addition consisted of a new 18,000kw 3,600rpm Westinghouse unit which brought the total capacity up to about 55,000kw. But even with the newest unit, the plant itself was comparatively obsolete by this point. In 1939, a massive $23 Million expansion program was undertaken in which the first of several state of the art 100,000+kw generating units were to be installed, one right after the other. The plant was retired in the early 2000's.

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.
