Construction of two 829 MW natural gas-fired combined-cycle generating stations consisting of two 400 MW single-shaft power trains. These plants use Siemens SGT6-8000H gas turbines, Siemens SST-5000 steam turbines, Siemens SGEN6-2000H hydrogen-cooled generators, Vogt “Smart-Box” Heat Recovery Steam Generators, and Air Cooled Condensers. Gemma constructed ancillary systems and buildings as well as the electrical interconnection facilities and tie-ins for natural gas, water, and wastewater. The plants supply the power needs of up to one million homes each and make a significant contribution to the Bradford County (PA) economy.
