Los Angeles’ power supply is now officially coal-free

Los Angeles has officially cut ties with coal. City officials say the Intermountain Power Project (IPP) in Utah – the last coal-fired power plant supplying the US’s second-largest city – went offline just before Thanksgiving.

IPP’s two massive units had a combined capacity of around 1,800 megawatts (MW) when fully operational, and as recently as 2024, they still supplied around 11% of LA’s electricity. The plant sits in Utah’s Great Basin region and powered Southern California for decades. Now, for the first time, none of LA’s power comes from coal.

There’s a political hiccup with IPP, though: the Republican-controlled Utah Legislature blocked the Intermountain Power Agency from fully retiring the coal units this year, ordering that they can’t be disconnected or decommissioned. But despite that mandate, no buyers have stepped forward to keep the outdated coal units online.

The Los Angeles Department of Water and Power (LADWP) is transitioning to newly built, hydrogen-capable generating units at the same IPP location, part of a modernization effort called IPP Renewed. These new units currently run on natural gas, but they’re designed to burn a blend of natural gas and up to 30% green hydrogen, and eventually 100% green hydrogen. LADWP plans to start adding green hydrogen to the fuel mix in 2026.

“L.A.’s coal divestment is not just about discontinuing the use of coal to power our city – it’s about building a clean energy economy that benefits every Angeleno. This milestone will further accelerate our transition to 100 percent clean energy by 2035,” said Mayor Karen Bass.

To reach that goal, LA is investing heavily in solar, wind, battery storage, and local programs that expand rooftop solar and energy efficiency.

One of the city’s biggest milestones was reached in August with the completion of the Eland Solar-plus-Storage Center – a massive project that pairs 758 megawatts of solar with 300 MW/1,200 MWh of battery storage. It’s one of the largest solar-plus-storage plants in the country, capable of powering more than 260,000 Los Angeles households. Bringing Eland online helped push LADWP’s power supply past 60% clean energy in 2025.
