Branch Energy Raises $33M for AI Power
Branch Energy has raised a $33 million Series B to deploy commercial batteries and aggregate them into virtual power plants as AI loads increase grid pressure.
AI data centres are running into a surprisingly old-fashioned constraint: the power grid. Branch Energy has raised $33 million to expand a distributed-energy model that can add flexible capacity without waiting years for new transmission.
What happened
The Series B was led by Piva Capital and Clean Energy Ventures.
Branch installs batteries at commercial buildings and aggregates them into virtual power plants. Those systems can lower customer electricity costs while also responding to grid conditions.
The company is expanding beyond Texas into the PJM electricity market, beginning with Illinois.
Why it matters
New data centres, electrification and industrial loads are increasing demand faster than many grids can build generation and transmission.
Distributed batteries can respond much faster. By coordinating thousands of smaller assets, operators can shift consumption or feed power back to the grid during periods of stress.
The bigger picture
The AI infrastructure boom is turning energy flexibility into a technology market of its own. Startups are competing not only to build new generation, but to make existing electricity systems more responsive.
Branch's model suggests commercial properties can become part of that infrastructure. If virtual power plants scale, the power system may increasingly rely on software-coordinated distributed assets alongside traditional centralised generation.
