High-voltage substation construction and transformer work across California. Here is the grid ESS operates in.
Natural gas remains California's largest single in-state generation source, though its share has fallen as solar has grown. Utility-scale and behind-the-meter solar together now supply roughly a third of the state's electricity, and the mix also includes hydroelectricity, nuclear from the Diablo Canyon plant, geothermal at The Geysers, and wind. California also imports a substantial share of its electricity from neighboring states.
Wildfire risk drives Public Safety Power Shutoff (PSPS) events, in which utilities de-energize lines during high fire-danger conditions. Heavy midday solar output creates steep evening ramp needs, a duck-curve pattern the state is increasingly managing with large-scale battery storage. California also depends on electricity imports and faces transmission constraints in moving power across its long, mountainous grid.
Shown as regional context, the major electric utilities and grid organizations operating in California. ESS builds substations and installs EHV apparatus across the western grid and has mobilized wherever the work is since 1978.
