HES Solar commissions sizable behind-the-meter energy storage project with Energy Toolbase

HES Solar and Energy Toolbase Project Site in Lakeside, California

Energy Toolbase sent word of a behind-the-meter energy storage project it commissioned with HES Solar, a San Diego-based, full-service solar development and installation company. HES Solar installed a BYD Chess energy storage system, integrated with Energy Toolbase’s Acumen EMS controls software, alongside a SunPower solar PV system for a Fortune 100 food and beverage industry client.

The 435-kW solar system was paired with a 240 kW/532 kWh energy storage system at a newly built, 125,000-square-foot distribution and warehouse facility in Lakeside, California. The Acumen EMS-operated energy storage system will reduce the host customer’s utility bill through demand charge management and time-of-use energy arbitrage. The combined project will save over $6 million in electric bills over the course of 25 years, according to HES Solar.

Energy Toolbase provides a lineup of project modeling, storage control and asset monitoring products for solar and storage developers. HES Solar and the host customer will have full visibility into the solar and storage operation via the ETB Monitor platform.

Energy Toolbase was the largest BYD Chess system reseller in North America in 2021 and has now commissioned or contracted its Acumen EMS on over 60 sites, totaling over 30 MWh of storage capacity, throughout the United States, Canada, and Mexico. Energy Toolbase rebranded its energy storage controls product to Acumen EMS in October of 2020, following its merger with Pason Power.

“I consider advanced control capabilities to be the core competence of a competitive energy storage software company,” said Michael Liu, the Senior Director of Energy Storage at BYD. “Energy Toolbase and HES Solar have been great partners to work with, and we are optimistic about deploying many more energy storage systems together in the future.”
