Mitsubishi Hitachi Power Systems (MHPS) has secured an order for the first advanced-class gas turbines designed to transition to renewable hydrogen fuel from Utah’s state-owned Intermountain Power Agency (IPA).
MHPS’s Lake Mary, Florida–based subsidiary MHPS Americas (MHPSA) on March 10 said that the contract for two M501JAC power trains are the first in the industry “specifically designed and purchased as part of a comprehensive plan to sequentially transition from coal, to natural gas and finally to renewable hydrogen fuel, and creates a roadmap for the global industry to follow.”
The advanced J-series turbines will be installed at the 1,800-MW Intermountain Power Project (IPP) in Millard County, which lies in the Great Basin region of western Utah.
IPA, which was established in 1977 under state law and today comprises 23 Utah electric utility–owning municipalities, owns that plant’s two existing 1986-completed coal-fired units. The units transmit 75% of their power through high-voltage lines to California (mainly to the Los Angeles Department of Water and Power [LADWP]) under power sales contracts that are set to expire in June 2027.
Because IPA could not secure new buyers for the power beyond that date, however, the agency plans to shutter both units by 2025.
The two new gas turbines will add an 840-MW facility to the site that IPA will own and LADWP will operate to serve Los Angeles and municipalities in California and Utah, MHPS said.
Under the order with IPA, MHPS will supply two 1-on-1 M501JAC power trains with gas turbines, steam turbines, heat recovery steam generators, and auxiliary equipment. MHPS will also service the plant under a 20-year long-term service agreement.
