Scattergood Generating Station Units 1 and 2 Green Hydrogen-Ready Modernization Project

Scattergood Generating Station Units 1 and 2 Green Hydrogen-Ready Modernization Project

The proposed project would replace the generation capacity of existing Scattergood Units 1 and 2, which are conventional natural-gas-fired steam boiler generators that would be removed from service, with a rapid-response combined-cycle generation system (CCGS) capable of operating on a fuel mixture of natural gas and a minimum of 30 percent hydrogen gas. The proposed CCGS would consist of a combustion-turbine generator and a steam-turbine generator operating in tandem. Additional facilities or ancillary functions required to support the proposed CCGS include a wet-surface air cooler, gas compressors, a potential dedicated pipeline for industrial wastewater discharge, and new circuit-breakers, disconnect switches, and H-frame structures for stringing conductors. Based on the findings of the Los Angeles 100 percent Renewable Energy Study (LA100), the proposed project has been identified as an integral component of LADWP’s Power Strategic Long-Term Resource Plan (SLTRP), which establishes the pathway to achieve a carbon-free energy system for the City of Los Angeles (City). The proposed project is necessary to maintain transmission reliability and resilience of the City’s electrical power grid during and after the transition to a carbon-free system. The deployment of additional firm capacity resources utilizing renewably derived hydrogen fuel will allow LADWP to meet future peak demands from load growth, address transmission contingencies, and support the accelerated buildout of clean energy projects. Construction of the proposed project is anticipated to begin in early 2026 and continue through mid-2029. The CCGS would be fully operational by the end of 2029.
