GRDA and Mitsubishi Execute Agreement for New 495-MW Combined Cycle Facility in Oklahoma
LCG, March 25, 2014 - Grand River Dam Authority (GRDA) and Mitsubishi Hitachi Power Systems Americas (MHPSA) announced yesterday that they have signed an agreement for MHPSA to supply GRDA with a new, combined cycle natural gas facility that will utilize the J-Series gas turbine. GRDA expects the new unit, with an electric generating capacity of 495 MW, to be operational by March 2017.
GRDA's Chief Executive Officer/Director of Investments stated, "This is an historic agreement for both GRDA and Mitsubishi. 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."
GRDA's CEO further stated, "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."
The new unit (GRDA Unit 3) will be located at the Grand River Energy Center (formerly GRDA Coal Fired Complex), about 56 kilometers east of Tulsa.
In January 2014, GRDA selected MHPSA to supply the M501J (328-MW) gas turbine, an SRT-50 (167-MW) steam turbine, and a generator to be supplied by Mitsubishi Electric Corporation.
