The Challenge

Veregy, a Phoenix-based project developer, was searching for a solution for the MSD Wayne Township school district, which expressed interest in adopting a holistic approach to energy management to reduce demand charges and support its energy savings targets over the next 25 years. The school district wanted to pair energy conservation measures (ECMs) with an energy storage system that could reduce demand charges, deliver substantial savings, support five sites in reaching net-zero targets, and assist the district in reducing over 12 million pounds of carbon dioxide emissions annually. Demonstrating their passion for reducing their carbon footprint, the customer leveraged HVAC systems, solar canopies, and LED lighting and sought renewable assets to continue doing so.

The Solution

To combat high demand charges, Veregy elected ETB Controller with Acumen AI™, paired with an all-in-one BYD energy storage system, totaling 720 kW/1,548 kWh in energy storage capacity across six sites. Configured for demand charge management, Acumen AI leverages dynamic economic dispatch to forecast load, reduce peak demand, and lower utility costs in real time. BYD’s modular approach allowed Veregy to stack the 120 kW / 258 kWh CHESS systems to fit the project size needed for the school district. The six-site portfolio distributed across MSD Wayne Township elementary schools is Energy Toolbase’s first multi-site battery storage project in Indiana and the state’s second-largest guaranteed energy savings contract. Implementing the energy storage system with ETB Controller and Acumen AI will contribute to a total guaranteed savings of $30 million.
