Using state-of-the-art combined cycle technology and a dry (air) cooling system, the 1,875 MW, Guernsey Power Station, will be a cost and fuel-efficient plant. Each power train, in its own turbine building, will consist of one GE 7HA.02 gas turbine equipped with evaporative inlet cooling, one triple pressure reheat steam turbine and one water/hydrogen cooled electric generator arranged on a common single shaft. Each power train will have an outdoor heat recovery steam generator (HRSG) equipped with supplemental duct firing capabilities, selective catalytic reduction technology for NOx, and an oxidation catalyst for CO/VOC reduction.
