About IPP Renewed
For more than three decades, the Intermountain Power Project (IPP) has served as a model of regional energy cooperation, generating and transmitting coal-fueled electricity to a diverse group of municipal utilities and rural electric cooperatives with operations across six U.S. states. As these entities’ current power purchase agreements near expiration, Intermountain Power Agency (IPA) is expanding its role as a regional energy hub, including utilizing renewable energy resources to produce and store hydrogen that can be drawn upon to generate carbon-free electricity.
Currently, renewable energy, such as wind and solar power, is not dispatchable. The transition to a 100% clean energy grid will require generating resources that are dispatchable and energy storage resources with long-term, even seasonal, capabilities, such as hydrogen. IPP’s proximity to the only major geologic salt dome formation in the west makes it the ideal location for siting and scaling up these emerging clean energy technologies.
Dubbed “IPP Renewed,” this transformational project includes the retirement of the existing coal-fueled units at the IPP site; installation of new natural gas-fueled electricity generating units capable of utilizing hydrogen for 840 megawatts net generation output; modernization of IPP’s Southern Transmission System linking IPP to Southern California; and the development of hydrogen production and long-term storage capabilities. Upon buildout of these facilities (see “Project Schedule”), IPP will use renewable energy-powered electrolysis to split water into oxygen and hydrogen, storing the latter in underground salt caverns for use as fuel to drive electricity-generating turbines. The new natural gas generating units will be designed to utilize 30 percent hydrogen fuel at start-up, transitioning to 100 percent hydrogen fuel by 2045 as technology improves.
Plans for IPP Renewed have been in development for over a decade by IPP participants. Going forward, these entities will continue to play key roles in the implementation of the project:
- Intermountain Power Agency–a political subdivision of the State of Utah with municipalities as members–is the project owner.
- Intermountain Power Service Corporation employs the people who work at IPP.
- Los Angeles Department of Water and Power—the largest purchaser of electricity from IPP—also serves as the Operating Agent and Project Manager.
