Branch Energy, a distributed energy company that provides battery storage systems to commercial buildings, has raised $33 million in a Series B funding round led by Piva Capital and Clean Energy Ventures.

Active Impact Investments and Whitecap Venture Partners participated in the round, along with existing investors Prelude Ventures, Zero Infinity Partners, and Inovia Capital.

The company deploys its proprietary Arc battery system at commercial properties, including warehouses, hotels, factories, and retail buildings. The self-contained system combines an industrial-grade battery, grid-connection equipment, cooling systems, autonomous controls, and cloud-based software in a container about the size of a parking space.

Branch installs and operates the systems without requiring building owners to make an upfront payment. The company handles permitting, installation, insurance, and operations and also serves as the retail electricity provider for the host business.

“Grids around the country need the distributed capacity that this system can supply, especially in states with fast-growing power demand, like Texas and Illinois,” said Lee Larson, Principal at Piva Capital. “Branch Energy is an essential solution for business owners to reduce their monthly electricity bill, and their optimized battery fleet reduces system-wide costs for all of us. We’re thrilled to partner with Alex and the excellent team he’s built at Branch on the next phase of scaling.”

Branch generates revenue by dispatching stored electricity to the grid or contracted offtakers, including hyperscalers. It also shifts electricity consumption from lower-cost periods at night to higher-cost periods during evening peak demand.

According to the release, the company is now expanding its services from Texas to Illinois, among other markets.

In February, Lunar Energy, a provider of integrated home battery systems and Virtual Power Plant (VPP) software, raised $102 million in an oversubscribed Series D round led by B Capital and Prelude Ventures. This funding follows a previously unannounced $130 million Series C round led by Activate Capital, bringing the total to $232 million.

According to Mercom’s recently released 1H 2026 Funding and M&A for Energy Storage report, VC funding for energy storage companies in 1H 2026 totaled $1.6 billion across 51 deals, representing a 6% YoY decline compared to the $1.7 billion raised across 36 deals in 1H 2025.
