Situated on a 10-acre site in Grand Terrace, this 200-MW/800-MWh battery energy storage system supplies electricity to around 150,000 homes for up to four hours during peak electricity demand periods.
It facilitates the operation of 220 Tesla Megapack 2XL and includes space for 660 CMA Augmented BESS units to maintain energy capacity over its 35-year design life. Across 280,000 work hours, the team had no recordable or lost-time incidents thanks to a comprehensive safety effort that included a craft empowerment program to ensure craftworkers' concerns were heard and an extensive site orientation processes for everyone who came on site.
A site recognition program linked with safety performance helped incentivize workers with rewards and recognition for delivering safety and quality.
All leadership and managers completed OSHA–30 within six months of being assigned, while all assigned safety managers had to maintain a Safety Trained Supervisor – Construction certification from the Board of Certified Safety Professionals, with most maintaining a Certified Health & Safety Technician or higher. The project was completed on time and within budget in June 2024.
