San Diego-based developer and installer HES Solar installed a 240-kW solar project at a newly-built distribution center in Lakeside, California. Solar modeling software developer Energy Toolbase commissioned the behind-the-meter project, pairing the system with a 532-kWh energy storage system.
The array uses SunPower modules, a BYD Chess Energy storage system and is integrated with Energy Toolbase’s Acumen EMS controls software. The solar + storage project was designed to reduce the host customer’s utility bill through a combination of both demand charge management and time-of-use energy arbitrage. HES Solar expects the array will reduce $6 million of electric bill costs over 25 years of operation.
“HES Solar has been a longtime, loyal user of Energy Toolbase’s modeling software,” said Ross Williams, CEO at HES Solar. “Our priority is to provide a safe and optimal storage system for our clients. We are excited to utilize both their Acumen EMS controls and ETB Monitor products as well.”
In 2021, Energy Toolbase integrated its controls software to work with BYD energy storage hardware. Energy Toolbase 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.
“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.”
