Fullmark Energy has reached commercial operations of its 65-MW/130-MWh San Jacinto storage project in Banning, California. The milestone marks the final project within Fullmark Energy’s Redwood Projects portfolio — a strategic collection of energy storage facilities across Southern California — to achieve commercial operations.
The Redwood Projects portfolio consists of four projects — San Jacinto, the 20-MW/80-MWh Johanna ESS project in Santa Ana (October 2021), the 20-MW/40-MWh Desert-Carris project in Palm Springs (2025) and the 20-MW/40-MWh Ortega Project in Lake Elsinore (2025).
The total portfolio provides 290 MWh of energy storage to the Southern California Edison distribution system.
“Reaching commercial operations across the Redwood Projects marks a major milestone for our team and our partners,” said Chris McKissack, CEO of Fullmark Energy. “These projects strengthen grid reliability, accelerate the renewable energy transition, and demonstrate our team’s ability to deliver high-performing assets at scale. San Jacinto is particularly meaningful because it shows how energy storage can simultaneously enhance grid infrastructure while revitalizing communities and creating value for local stakeholders.”
The San Jacinto facility sits on previously abandoned property that had become an overgrown nuisance, creating challenges for surrounding residents and businesses. Working closely with local stakeholders, Fullmark transformed the site into well-maintained infrastructure with proper security fencing and lighting, significantly improving conditions for the neighborhood. The project also generates economic benefits for the City of Banning’s municipal electric utility, which serves approximately 13,500 customers and serves the project’s load.
