CH2M Hill has completed a new $700m gas-fired combined-cycle power plant in New York for Empire Generating Co.

The company was the EPC contractor for the plant, which has a base load generating capacity of 535MW.

The plant can also have peaking power generating capacity of up to 635MW, enough power for approximately 700,000 homes.

The power station includes two GE 7FA dual fuel combustion turbines, two Alstom three-pressure heat recovery steam generators, one GE D-11 reheat steam turbine, an eleven cell GEA cooling tower and on-site water treatment facility.

The plant is primarily fueled by natural gas and is also capable of running on low sulfur fuel oil.

CH2M Hill’s scope of work also included the construction of a 345kV switchyard, eight miles of 345kV transmission line, a 16-inch diameter gas line for 4.5 miles, and a low noise and plume-abated cooling tower.

CH2M Hill is a provider of consulting, design, design-build, operations and program management services for government, civil, industrial and energy clients.
