An unparalleled track record of converting potential projects to gigawatts in the ground.

New Leaf Energy is a renewable energy developer focused on delivering projects that accelerate the transition to a world powered by renewable energy. Informed by our depth of experience in multiple markets, we are able to navigate the intersection of emerging technology and new markets, opening up new ways of delivering clean energy at scale.

Our roots extend back to 1980. Our business, leadership, and employees originated from the development arm of Borrego, a leading national EPC and O&M provider. We have been developing solar projects for more than 20 years—first in California, then New England, New York, Illinois, Maine, and beyond—and energy storage since 2016. 

In July 2022, ECP purchased Borrego’s development arm to establish New Leaf Energy as an independent company, in service of its mission to accelerate the adoption of renewable energy. At that time, long-time Borrego executive Dan Berwick became CEO of New Leaf Energy.

Headquartered in Lowell, MA, with offices in Boston, Chicago, Troy, and Oakland, New Leaf Energy now has one of the most diverse pipelines of renewable energy and energy storage projects in the United States. As a company, we prioritize the transition to clean energy above all else: We identify projects that are of the greatest value to a decarbonizing electricity system, and we are bold and fearless in developing them.
