Intermountain Power Plant is a large coal-fired power plant at Delta, Utah, US. It has an installed capacity of 1,900 MW, is owned by the Intermountain Power Agency, and is operated by the Los Angeles Department of Water and Power (LADWP). The plant includes a HVDC converter. It is scheduled for replacement in 2025 with an 840 MW natural gas plant, designed to also burn "green hydrogen."
Read more on WikipediaThe Intermountain Power Project is a hybrid power plant located in Millard County, Utah. It has a total capacity of 2480 MW across 4 generators, making it the largest power plant in Utah and the sixth largest in the United States. The plant began operating in 1986 and is owned by the Intermountain Power Agency, with the Los Angeles Department of Water & Power (LADWP) serving as the operator. The primary fuel source is bituminous coal, but the plant also utilizes natural gas-fired combined cycle technology.
In the most recent year with available data, the Intermountain Power Project generated 4,803,126 MWh of electricity, resulting in a capacity factor of 22.2%. The plant operates within the Los Angeles Department of Water and Power balancing authority and is located in the Western Electricity Coordinating Council (WECC) NERC region.

This plant's balancing authority participates in CAISO's Western Energy Imbalance Market (WEIM). Direct nodal pricing data is not yet available.
No wholesale contracts disclosed in FERC EQR for this plant.
FERC EQR captures bilateral wholesale energy + capacity contracts ≥$1M/yr filed quarterly by jurisdictional sellers — covers renewable PPAs, thermal energy sales agreements, capacity contracts, and tolling agreements alike. Many plants don't appear: regulated-utility output flows to ratepayers via cost-of-service rather than bilateral contracts; small projects fall below the filing threshold; tax-equity-financed renewables route offtake to investors not utilities; merchant plants sell into ISO clearing markets without bilateral contracts. News-extracted buyer facts (below) may surface contracts disclosed only through announcements.
