The Grand River Energy Center (GREC), owned by Oklahoma’s state-owned electric utility Grand River Dam Authority (GRDA) and KAMO Power, is located in Chouteau, Oklahoma, US. It consists of two coal-fired units; a 490MW unit one and 520MW unit two.

GRDA started construction of a new 495MW combined cycle gas turbine (CCGT) unit in January 2015 at an estimated cost of $296m. The new natural gas-fired unit will be located adjacent to the existing units and started operations in March 2017.

Unit two were retrofitted to control emissions in accordance with Environmental Protection Agency (EPA) standards in 2016.
