TWAICE Partners with Fullmark Energy to Power 290 MWh of Battery Storage with Data Analytics in CAISO Market

TWAICE, a leading provider of predictive analytics software for battery energy storage systems (BESS), announced a three-year partnership with Fullmark Energy (“Fullmark”) for its Battery Storage Analytics platform to support four energy storage installations operated by the independent power producer (IPP). The Southern California sites will have a total capacity of 290 MWh when complete. This new partnership adds to a growing portfolio of large-scale storage assets operated with TWAICE analytics across CAISO and other major U.S. markets.

Fullmark is currently using TWAICE Battery Storage Analytics at their 20 MW/80 MWh “Johanna” BESS facility in Santa Ana, CA. They will connect TWAICE to three additional sites—ranging from 40 MWh to 130 MWh—as they become commercially operational.

“We are excited to partner with Fullmark Energy in one of North America’s most critical energy markets,” said Lennart Hinrichs, Executive Vice President and General Manager Americas at TWAICE. “Fullmark’s Southern California projects will play a vital role in ensuring grid reliability for the state. Our analytics enables Fullmark to run at peak performance while staying fully compliant with CAISO standards. We look forward to expanding our collaboration across Fullmark sites as they continue to set the standard as a leading independent power producer.”

TWAICE Battery Storage Analytics turns raw data from Fullmark’s storage systems into actionable insights for engineers and asset managers. Instead of reconciling data from multiple systems and manually chasing down performance issues, teams get accurate state of charge (SoC) calculations, fleetwide monitoring, and clear recommendations, including pinpointing the causes of stranded energy to boost availability and revenue.

“Gathering and analyzing the data needed to truly understand our energy storage assets is a significant undertaking,” said Chris Swanson, Director of Performance Engineering at Fullmark Energy. “With TWAICE, one person can manage an entire BESS while meeting CAISO power delivery requirements with an accurate SoC.”

These intuitive insights make it possible for even lean teams to manage complex storage portfolios, streamline reporting, and ensure compliance with power delivery requirements.

“TWAICE helps me confidently report to our executive team and investors,” added Nicholas Peri, VP of Asset Management & Operations at Fullmark. “The platform translates complex battery data into actionable insights that drive better decisions and build trust.”
