Mitsubishi Power will provide a second J-series advanced-class gas turbine to the Grand River Dam Authority’s (GRDA) Grand River Energy Center in Chouteau, Oklahoma. The M501JAC gas turbine will provide operational flexibility and fast start-up times to meet GRDA’s electricity grid requirements, under the agreement.

The project’s construction is expected to begin January 2024, with operations set to begin April 2026. The gas turbine is located at the Center’s Unit 3 project, a 500 MW gas turbine combined cycle (GTCC) power station, which started operations in 2017.

The M501JAC enhanced air-cooled gas turbine for Unit 4 will replace the Energy Center’s Unit 2, a 492 MW coal-fired generator introduced in 1985, resulting in reduced emissions, providing a long-term resource for affordable and reliable power, and helping meet efficiency goals.

“By replacing its coal-fired units with our advanced J-Class gas turbines, including Unit 4’s hydrogen-capable turbine, GRDA is demonstrating its continuing commitment to cleaner, more flexible, and reliable energy production,” said Bill Newsom, President and CEO of Mitsubishi Power Americas.

The Unit 4 gas turbine is hydrogen-capable and can be operated on a blend or 100% hydrogen in the future.

The agreements include the performance of long-term service and maintenance, replacement parts supply, and remote monitoring of the units.
