SEC 03 — Recognition
Industry awards
Selected recognition for engineering, emissions performance, and innovation in dispatchable hybrid operation.
A privately held developer and operator of energy generation and storage facilities across California. Forty years on the grid — designing, permitting, building, and dispatching the capacity a renewables-heavy system depends on.
Six disciplines under one roof — development, permitting, construction, operations, maintenance, and research.
Fast-start peaking and reliability generation, 45–98 MW class, sub-10-minute starts. Engineered for grid stability in a renewables-heavy mix.
Enhanced Gas Turbine architecture — gas turbines and battery storage dispatched as one asset. ~60% reduction in start emissions.
Standalone BESS and co-located solar from greenfield through commercial operation, interconnection, and dispatch optimization.
CEC, AFC, CPUC, SCAQMD, SDAPCD, SJVAPCD. Twelve filings since 1982 — every one reached commercial operation.
In-house operations across the fleet, manned 24/7. The same engineering team from design through thirty years of operation.
First commercial integrated hybrid gas-battery facility in the U.S. Active research in hydrogen blending and long-duration storage.
Eight operating facilities across three California air districts. Every megawatt developed by Wellhead is still operated by Wellhead.
