On March 21, Grand River Dam Authority (GRDA) Chief Executive Officer/Director of Investments Dan Sullivan signed a contract with Mitsubishi Hitachi Power Systems Americas for the purchase of a combined cycle unit.
That unit, to be called GRDA Unit 3, will not only have the capability to produce 495 MW, but it also has the potential to be the most efficient of its kind in the United States, the authority said in a March 24 statement. Unit 3 will be located at the Grand River Energy Center (formerly GRDA Coal Fired Complex), situated east of Chouteau, Okla. GRDA anticipates the new Unit 3 to be operational by March 2017.
Sullivan signed the agreement, along with Yoshihiro Shiraiwa, President of Mitsubishi Hitachi Power Systems Americas, during a special ceremony at the GRDA Engineering and Technology Center in Tulsa.
“This is an historic agreement for both GRDA and Mitsubishi,” said Sullivan. “This unit will be the first of its kind in the western hemisphere. It is state-of-the-art technology, and as a combined cycle unit, it will operate very efficiently while providing low-cost, reliable electricity for GRDA customers for decades to come.”
Sullivan added: “Part of the GRDA Board’s strategy is to reduce our reliance on coal. We can achieve some of that with this new facility. By burning natural gas from right here in Oklahoma, we will have a diversified generation portfolio that will continue to keep costs low for our customers.”
Headquartered in Vinita, GRDA is Oklahoma’s state-owned electric utility.
