Drinking Water Permit

2017

Potable-water systems CA3601184 and CA3601185

California drinking-water records identify the Mojave Solar Project Alpha and Beta Power Plant potable treatment facilities as nontransient, noncommunity groundwater systems CA3601184 and CA3601185. The project compliance language required a County of San Bernardino operating permit and annual renewals or updates for the nontransient, noncommunity system.

Emissions Control

Nov 14, 2013

Two natural-gas auxiliary boilers replaced with two heat-transfer-fluid electric heaters

CEC staff approved a 2013 modification replacing two 21.5 MMBtu/hr natural-gas-fired, low-NOx auxiliary boilers with two heat-transfer-fluid electric heaters, lowering project emissions. The plant's primary electrical output is solar thermal; the CEC separately notes diesel firewater pumps and a diesel backup generator for essential power and fire protection.

Common questions about Mojave Solar Project

Answered from the published record above. Questions whose inputs this profile does not carry are omitted rather than estimated.

How big is Mojave Solar Project?

Mojave Solar Project reports 280 MW solar of operating nameplate capacity. These technology ratings do not establish a common export limit. Source: EIA Sep 2026.

What kind of plant is Mojave Solar Project?

Mojave Solar Project is a Solar Thermal without Energy Storage facility in San Bernardino County, CA, participating in the CAISO market.

Where is Mojave Solar Project located?

Mojave Solar Project is in San Bernardino County, CA, inside the CAISO balancing area.

Who operates Mojave Solar Project?

Mojave Solar Project is operated by Mojave Solar LLC according to the EIA generator inventory. Reporting membership does not by itself establish ultimate ownership.

How much electricity does Mojave Solar Project generate?

Mojave Solar Project reported 647.1 GWh over the twelve months to 2026-07. For a storage plant this is reported gross generation — a discharge proxy, not a cycle count or a conventional capacity factor.

How does Mojave Solar Project compare to other plants?

By capacity, Mojave Solar Project ranks #1 of 6 operating plants of the same technology nationally. It ranks #1 of 5 in CA.
