Nexamp and Energy Toolbase Deploy Front-of-the-Meter Energy Storage System in Massachusetts

Nexamp Deploys Acumen EMS™ at a Solar Farm to Mitigate Demand Charges and Decrease Utility Costs for Local Residents

Energy Toolbase andNexamp have deployed a front-of-the-meter energy storage system as part of one of Nexamp’s solar + storage projects in Massachusetts. Nexamp, a Boston-based solar and energy storage company, commissioned a Sungrow energy storage system comprised of four units, fully integrated with Energy Toolbase’sAcumen EMS™ controls software, as part of the Old Frontier III community solar site. This project is Energy Toolbase’s first controls project with Nexamp, which is currently working toward commissioning additional solar projects throughout Massachusetts.

Sited in Deerfield, Massachusetts, the 1,000 kW/2,192 kWh Acumen EMS-controlled energy storage system is Energy Toolbase’s first DC-coupled project. It leverages the Solar Massachusetts Renewable Target (SMART) and Clean Peak Standard programs, which both incentivize clean energy technologies that promote solar and storage development and supply electricity during peak demand periods.

As part of Nexamp’s industry-leading national community solar program, the Old Frontier Solar III farm gives residents the opportunity to subscribe to a local community solar farm and support the expansion of solar with no up-front cost and no equipment to install. Residents subscribing to the Old Frontier Solar III farm receive credits on their electric utility bill for energy produced by their solar farm share and are billed for the value of those credits at a fixed discount, making community solar a risk-free and cost-effective way to advance clean energy generation while reducing costs.

“We’re excited to bring our Acumen EMS controls software into the Northeast market, especially on a large front-of-the-meter project with a trusted developer like Nexamp,” said Kevin Mulvey, Vice President of Operations at Energy Toolbase. “The Northeast storage market is growing quickly, and Energy Toolbase plans to deploy many more projects that will contribute to the growth.”

“Controlling every aspect of the energy storage system—from energy capture to strategic discharge—is critical in maximizing the value and impact of this rapidly developing technology,” noted Rob Ritchie, Director of Energy Storage, Nexamp. “Our relationship with Energy Toolbase enables us to get the most from every project while ensuring that we deliver on the promised benefits for our partners and customers.”
