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.
