Goodwin Advises Branch Energy on $33 Million Series B

The Technology team advised Branch Energy on a $33 million Series B funding round led by Piva Capital and Clean Energy Ventures, with participation from Active Impact Investments and Whitecap Venture Partners, and existing investors Prelude Ventures, Zero Infinity Partners, and Inovia Capital. The funding is set to expand Branch’s Arc battery system, a proprietary, self-contained “grid in a box.” Everything needed to store and deliver electricity fits inside one container about the size of a parking space. Branch is building toward tens of thousands of Arcs across the United States under long-term capacity agreements.

Branch Energy is a distributed energy company that makes it easy for commercial buildings to lower their energy bills while providing backup power at no cost.

The Goodwin team was led by Harley Brown, Nisha Siedor, Chris Turnbull, and Giselle Rivers.
