Our power plant
EcoEléctrica is a combined cycle cogeneration plant with two 501F 184MW combustion turbines designed and built by Siemens-Westinghouse. The turbines use natural gas as a primary fuel, but can also use liquefied petroleum gas (LPG) as a secondary fuel, and No.2 oil with a very low sulfur content (0.04%) as a backup or emergency fuel. The exhaust gases from the combustion turbines are routed to heat recovery steam generators (HRSGs) to produce steam.
Part of the steam is routed to a Toshiba steam turbine/generator to produce an additional 214 MW and to a desalination plant to provide heat for sea water distillation purposes. Steam is also used to control NOx emissions. The power generated by EcoEléctrica is transmitted to the Puerto Rico Electric Power Authority (PREPA) system on a 230 kV line.
