The new storage division will be based in Massachusetts, on the opposite side of the country from Borrego’s headquarters in San Diego, California, and will offer both standalone storage solutions and battery systems integrated with PV.

Borrego says the division's near-term focus will be securing utilities as clients, developing and installing grid-scale battery systems to help them with renewables integration and peak-load management.

Borrego also intends to go back and offer storage solutions to the owners of the 400MW of PV capacity it has built over the years.

The new storage division will be led by Dan Berwick, Borrego’s executive vice president of strategy and business development.

The launch represents the first time in Borrego’s 35-year history that it will venture into energy services beyond PV.

The company currently focuses on designing, building and maintaining large rooftop and small ground-mount solar systems for clients ranging from big corporations to universities – using equipment from the likes of Suniva, Canadian Solar and SMA Solar.

“We’re realising that across our customer base – from cities, school districts and public agencies, to businesses, manufacturers and electric utilities – it is more frequently making economic sense to evaluate energy storage in conjunction with solar,” Berwick says.

Borrego will be competing in an increasingly crowded storage sector, which includes players like Engie-owned Green Charge and SolarCity, which is in the process of being acquired by Tesla.
