Overview
- City officials say Utah’s Intermountain Power Project stopped coal operations just before Thanksgiving, ending LA’s last coal-sourced electricity.
- IPP’s retired coal units totaled about 1,800 MW and supplied roughly 11% of Los Angeles’s power as recently as 2024.
- The site’s IPP Renewed combined-cycle units are running on natural gas and are built to blend up to 30% green hydrogen initially with a pathway to 100% hydrogen.
- LADWP plans to begin introducing green hydrogen in 2026, supported by on-site electrolysis and planned salt-cavern storage for multi-day energy buffering.
- The utility approved nearly $800 million to retrofit Scattergood Units 1 and 2 into hydrogen-ready, rapid-response capacity starting in 2026, as regulators and neighbors scrutinize NOx, water use, and safety.
