Energy Toolbase Deploys 2-Megawatt Energy Storage System with Socomec Providing Critical Load Backup at California Mall

Acumen EMS™ and Socomec Battery System Installed at Shopping Mall to Provide Critical Backup to Tenants During Blackouts

Energy Toolbase, Blue Sky Utility, and BPi Power have implemented two energy storage systems (ESS) at a sprawling 328,878-square-foot shopping mall in Hanford, California. Leveraging Energy Toolbase’sAcumen EMS™ controls software and Socomec’s cutting-edge battery technology, the deployment aims to ensure uninterrupted power supply to the mall during utility outages.

Blue Sky Utility, a renewable energy developer based in California, sourced the ESS from Energy Toolbase. Installed byBPi, a Napa-based solar energy contractor, are twoSocomec HES L batteries integrated with Acumen EMS controls software, boasting a total energy storage capacity of 500kW/2,372kWh. This setup complements the existing 1.5-megawatt solar system at the mall. Notably, the ESS is equipped for value stacking, offering demand charge management, and can also function in islanding mode for backup power.

The partnership between Energy Toolbase and Socomec brings together top-tier battery technology and advanced controls software to provide optimal savings and maximized value. Employing a value-stacking control strategy, the systems effectively trim peak demand charges, with a fallback to arbitrage when peak shaving is not anticipated. The Socomec systems feature an island mode capability, ensuring critical load backup during utility outages, and can fully charge from the existing solar array. With the integration of Energy Toolbase’s asset monitoring software,ETB Monitor, both the developer and the customer gain a unified interface for monitoring the real-time performance of the systems.

“Energy Toolbase is excited to once again partner with the Blue Sky Utility team to bring more energy storage to California,” said Kevin Mulvey, Vice President of Operations at Energy Toolbase. “The islanding capability of these systems will play a big role in tapping into even more savings possibilities.”

“This unique project is designed to provide Hanford Mall energy from the sun, every evening after sunset,” said Allon Raveh, Executive Chairman at Blue Sky. “We are a pioneer in deploying creative solar and storage solutions in central locations, supporting grid resiliency and a better world for our people and our planet.”
