WE design & BUILD custom energy storage systems for utilities and COMMERCIAL energy users

Energy storage systems make economic sense for a growing section of commercial energy users and utilities. At the most basic level for commercial users, batteries store energy when it is cheap and plentiful, and discharge at times when it is more expensive such as during peak hours or periods of high power demand. For utilities, energy storage can be used to delay grid upgrades or help alleviate the “duck curve” caused by day-time solar energy loading onto the grid.

With an unmatched track record for engineering and building successful solar projects over the last 40 years, our veteran design & project management teams deliver the same expertise to solar plus storage & standalone energy storage projects. We maintain the in-house expertise to design, engineer, permit, procure, manage, install, interconnect, inspect, finance, and maintain energy storage systems — offering our customers and partners a turnkey process that helps them get the most value from their renewable energy assets.

“From project development through commissioning; the company’s attention to detail, engineering sophistication, and depth of experience with distributed energy was evident. Borrego Solar is the kind of capable partner National Grid will look for as we continue our advances in solar connectivity, energy storage and other distributed energy resources for our customers.”
Fouad Dagher, P.E., Director NES Customer Solutions, National Grid

Large-scale electricity customers in CA, NY and MA can save money with energy storage systems by lowering demand charge spikes, by optimizing storage with certain time-of-use rates, by reducing capacity charges, and by operating at a more optimal power factor.


Utilities can use energy storage systems to defer the need to upgrade transmission and distribution equipment, resulting in near-term savings on operating expenses. When combined with solar, storage can be used to reduce the need for expensive interconnection-related upgrades.
