The company has ordered two M501JAC power trains for the Intermountain Power Plant in Delta, Utah. The gas turbine technology will enable the transition from coal to a carbon-free power generation by 2045.
The utility-scale project will initially generate electricity from a mix of hydrogen (30%) and gas (70%) fuel. This mix will cut carbon emissions by over 75% compared with the retiring coal-fired technology. The project’s development will run from 2025 until 2045, when power is planned to be generated from 100% renewable hydrogen.
The Intermountain Power Agency (IPA) will own the 840-megawatts plant and the Los Angeles Department of Water and Power (LADWP) will operate it. The facility will supply IPA customers in Los Angeles, other parts of California and Utah. It’s already connected to the LA power grid.
The plant will be fed by hydrogen produced through electrolysis, via an adjacent energy storage project known as ACES. The hydrogen will be stored in an underground salt dome at the site, using technology that has already been in operation for the past 30 years to supply hydrogen to U.S. refineries in the Gulf Coast.
The carbon-free fuel provides power when wind and solar availability are limited due to prevailing weather conditions and time of day. It also provides seasonal energy storage from renewable energy sources.
Mitsubishi didn’t disclose financial details of the contract.
