Located at the Port of Acajutla, the project is composed of three components: thermal power plant, LNG regasification terminal, and transmission line.
378-Megawatt Thermal Power Plant
This clean and efficient combined cycle power plant will generate electricity from nineteen 18V50SG natural gas-powered reciprocating engines (each rated at 18.9 MW) and one 28-megawatt steam turbine generator powered by steam produced from the heat recovered in each engine’s exhaust. The combination of gas and steam generation will achieve efficiencies in excess of 49% percent (LHV).
Marine/LNG Regasification Terminal
EDP features the first-ever permanently moored Floating, Storage and Regasification Unit (FSRU) on the Pacific coast of the Americas. Super-chilled (−162 °C / −260 °F) liquefied natural gas (LNG) delivered to the FSRU will be converted back to natural gas at atmospheric temperature and transported from the FSRU to the power plant via a subsea pipeline.
Transmission Line
A 44-kilometer, 230 kV double circuit transmission line from Acajutla to Ahuachapan, and its associated substations, will strengthen the country’s electric grid and connect the power plant’s output to the Central American Electrical Interconnection System (SIEPAC).
