Grand River Dam Authority (GRDA), Oklahoma's state-owned electric utility, has selected Mitsubishi Heavy Industries (MHI) to supply an M501J gas turbine for the Chouteau power station in the US.

Gas turbine is the core component of a gas turbine combined cycle (GTCC) power generation system.

MHI’s wholly owned subsidiary, Mitsubishi Power Systems Americas will supply the core component for the 495 MW GTCC plant to be built at the facility in Chouteau.

The new GTCC plant is scheduled to become operational in March 2017.

The contract includes an M501J gas turbine, an SRT-50 steam turbine and a generator.

The gas turbine will be manufactured at Savannah Machinery Works in Savannah, Georgia, which is MHI’s manufacturing base in the US.

Mitsubishi Electric Corporation will supply the generator. A separate long-term service agreement (LTSA), which includes maintenance of the plant, replacement parts supply and remote monitoring after the plant operation commencement, is planned to be signed.
