Texas Retail Provider Raises $33M Series B, "To Deliver AI Power in Weeks, Not Years"; Series B Supports Geographic Expansion
The following story is brought free of charge to readers by VertexOne, the exclusive EDI provider of EnergyChoiceMatters.com
Branch Energy announced 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.
Branch said that the Series B will support Branch’s answer to the challenges of electricity availability and the current extended timelines to connect new generation needed for AI data centers and electrification
"Branch’s answer is the Arc: 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: an industrial-grade battery, grid connection equipment, cooling, autonomous controls, and the software that lets Branch run it safely and securely from the cloud," Branch said
Under this offering, Branch becomes the retail electricity provider for the host business of Arc, "locking in lower rates for future years by optimizing the battery’s charge and discharge cycle," Branch said
Branch installs Arc on-site at commercial buildings (warehouses, hotels, factories, retail, etc.). Branch said that the systems are delivered by flatbed trucks and can be installed in just two days.
"Our customers get guaranteed savings and free backup power. The grid gets capacity it badly needs," Branch said of the offering
Branch is now expanding its services from Texas to Illinois, among other markets.
"Branch’s model enables the building owner to avoid upfront payment for the system, with Branch handling permitting, installation, insurance, and operations. Branch also becomes the retail electricity provider for the host business, locking in lower rates for future years by optimizing the battery’s charge and discharge cycle. The host provides a parking-space-sized plot of land and receives guaranteed savings on their energy bill, in addition to backup power during outages. Branch’s revenues come from the electricity market by dispatching the battery's stored capacity to the grid or to contracted offtakers such as hyperscalers, and shifting energy from low-cost periods at night to high-cost periods during daily evening peaks," Branch said
“Hyperscalers need power, and they need it now,” said Alex Ince-Cushman, Co-Founder and CEO of Branch Energy. “We can do it on the timeline of a delivery, not a construction project. Our customers don’t lift a finger, don’t pay a dime, and get guaranteed savings.”
Branch said, "PJM, the regional grid operator for Illinois, has recently opened a path for large energy users like data centers to connect sooner when bringing their own capacity to the grid. Branch builds the most reliable way to deploy this capacity quickly: via Arc autonomous batteries deployed across unused parking lots, behind meters that already exist, and with no new land, permits, or transmission lines required. PJM’s territory holds roughly 1.2 million commercial buildings and covers 20% of US national electricity demand, representing an extraordinary market opportunity for Branch."
"Branch is building toward tens of thousands of Arcs across the United States under long-term capacity agreements. A fleet that size carries billions of dollars of annual revenue," Branch said
