"In 1999, NRG acquired the 15-acre Astoria Gas Turbines site from Con Edison, which is situated within a larger 300+ acre complex. This complex has hosted electrical generation, transmission, distribution and associated energy activities since the 1890s and remains exclusively a major electric generating and manufacturing complex. In 1999, the site consisted of 33 gas turbine units with total generating capacity of 646 MW. In 2010, NRG proposed to replace the units with a 1,040 MW combined cycle facility. NRG’s modified 2020 Project proposes to replace the 24 remaining units with a single new state-of-the-art simple cycle GE combustion turbine generator having a total generating capability of 437 MW."
