Energy Toolbase and leading San Diego-based solar company, Stellar Solar Commercial, have partnered to implement an advanced energy management solution at a 23-acre transportation terminal campus in Mira Loma, California. By utilizing Energy Toolbase's Acumen EMS™ controls software and BYD's pioneering battery solutions, this installation aims to significantly reduce demand charges and smooth out demand peaks, achieving substantial long-term electricity bill savings.

As a long-time customer of Energy Toolbase, Stellar Solar leveraged Energy Toolbase's project modeling platform, ETB Developer, to model the project's potential savings by adding a storage system, allowing Stellar Solar to predict the system's performance in the field accurately and present it to their customer. Energy Toolbase facilitated the rapid procurement and deployment of a 60kW, 4-hour BYD Chess energy storage system (ESS), integrated with Acumen EMS controls software, to complement the facility's existing 197kW solar system.

The primary control application for the ESS is Time-of-Use (TOU) Demand Charge Management to optimize peak-shaving during all TOU periods by discharging the battery when the site's metered demand rises above thresholds calculated by Acumen EMS for each TOU period. This keeps the site's metered demand under control, ensuring that the customer receives maximum value from their energy assets. The system's real-time performance and savings are fully visible to Stellar Solar and critical stakeholders through ETB Monitor. This tool provides comprehensive insights into the ESS's operations and enables continuous assessment and optimization.
