Together, the two companies will roll out a nationwide program to offer Spruce’s extensive customer base a seamless path to upgrade existing solar systems with energy storage, delivering resilience, control, and long-term energy savings.

“Battery storage is the next wave of value creation in distributed energy, and Spruce is built to lead it,” said Chris Hayes, CEO of Spruce Power. “Our partnership with Treehouse gives us the ability to rapidly activate our massive installed base and capture the upside of storage adoption, without the capital intensity of traditional deployment.
