Rabot Energy Raises €50M Series B to Wire Households Into Virtual Power Plants

Rabot Energy has raised €50 million (USD $56 million) in a Series B round, with proceeds earmarked for linking household battery storage systems into virtual power plants across Germany. The round, announced by the Hamburg-based climate tech company, was led by European growth investor Endeit and joined by DeepTech & Climate Fund (DTCF), HV Capital, High-Tech Gründerfonds, Bosch Ventures, CNI, Acurio Ventures and vent.io.

Founded in 2021, Rabot Energy supplies dynamic electricity tariffs and AI-powered energy management to households. Its stack combines a dynamic tariff, a smart meter and a plug-and-play battery storage system. The batteries charge when renewable electricity is plentiful and cheap, and discharge when supply tightens and prices rise. According to the company, the solution cuts electricity costs for an average household by 15%.

What does the funding change?

The new capital will accelerate the rollout of Rabot's offerings to private households as well as commercial and industrial customers in Germany. The company also plans to further develop its technology platform and integrate additional devices — battery storage systems, wallboxes and heat pumps.

The scale target is concrete. Rabot aims to grow its customer base from more than 200,000 today to one million.

CEO Jan Rabe framed the strategy as interconnection rather than construction. "The next generation of power plants won't be built, it will be interconnected," he said. "Millions of households hold enormous, untapped potential: not just to consume energy, but to intelligently integrate it into the overall system."

With Series B, Rabe said, Rabot is "transforming individual households into a network that stabilizes the electricity system, accelerates the energy transition, and, as a bonus, significantly reduces our customers' electricity bills."

Why distributed flexibility now?

Rabot said the funding arrives as the electrification of mobility and heating, together with the expansion of renewable generation, raises the importance of optimizing consumption and managing storage flexibly. By aggregating household batteries into virtual power plants, the company wants to build a decentralized energy infrastructure that supports renewable integration, lowers electricity costs and reduces Europe's dependence on fossil fuel imports.

Dr. Anne Hinze, Senior Investment Manager at DTCF, pointed to the market mechanics behind the pitch. "Rabot Energy addresses a key challenge of the energy transition: With innovative energy tariffs and an intelligent energy management platform, the company enables households to benefit from the dynamics of an increasingly volatile energy market," she said.

The milestone to watch is the customer count. Whether Rabot converts its €50 million into a fivefold expansion — from 200,000 households toward one million, with wallboxes and heat pumps added to the platform — will decide whether Germany's distributed batteries become a dispatchable grid asset or remain a bundle of individual tariff products.
