What if millions of homes could do more than consume electricity and instead help balance the power grid? German energy technology company Rabot Energy is working towards that future after raising 50 million in Series B funding to expand its smart energy platform, connect more household devices and build a network of distributed battery storage systems that could operate like a virtual power plant.
The funding round was led by Endeit, a growth capital investor focused on European technology companies, alongside the DeepTech & Climate Fonds. Existing investors HV Capital, High Tech Gründerfonds, Bosch Ventures, CNI, Acurio Ventures and vent.io also participated. The company plans to use the investment to accelerate growth and move towards its target of reaching one million customers.
Making Electricity Consumption Smarter
Founded around the idea of flexible energy consumption, Rabot Energy offers dynamic electricity tariffs that reflect changing wholesale market prices. Electricity prices can fluctuate depending on demand and the availability of wind and solar power, creating opportunities for customers to save when they use or store electricity during cheaper periods.
Rabot Energy uses digital tools and intelligent automation to help households shift electricity consumption towards these lower cost periods. Instead of requiring customers to constantly monitor prices, its platform can coordinate connected devices and optimise when they consume electricity.
The approach is becoming increasingly relevant as electric vehicles, heat pumps and other technologies increase electricity demand. Greater flexibility can help consumers manage costs while making better use of renewable energy when generation is high.
Rabot Flow Opens the Door to More Households
In June 2026, the company introduced Rabot Flow, a combined offering that brings together a dynamic electricity tariff, a smart meter and a plug and play home battery.
According to Rabot Energy, the solution can reduce an average household’s energy costs by 15 per cent. The battery connects to a standard electrical socket, does not require a rooftop solar installation and can be used by people living in rented accommodation.
The model broadens access to energy storage beyond homeowners who can install solar panels and larger battery systems. By charging when electricity is cheaper and releasing stored power when needed, households can potentially reduce their exposure to higher prices.
Building a Virtual Power Plant
A major part of Rabot Energy’s strategy is to connect individual home batteries into a coordinated network. This virtual power plant model could allow thousands of household storage systems to respond collectively to changing electricity demand and supply.
When renewable generation is abundant, connected batteries can store electricity. When supply becomes tighter, stored energy can be used by households, potentially reducing demand during peak periods and easing pressure on the grid.
Jan Rabe, CEO of Rabot Energy, said the next generation of power plants would be connected rather than simply built. He believes households have significant untapped potential to become active participants in the wider energy system.
Rapid Growth Fuels Expansion Plans
Rabot Energy says it has attracted more than 200,000 customers in three and a half years, including approximately 15,000 commercial and industrial clients. The company has also reached €200 million in revenue and reports supplying more than 600 million kilowatt hours of renewable electricity to its customers.
The new funding will support expansion across residential, commercial and industrial markets in Germany, alongside further development of its proprietary technology platform.
Connecting the Next Generation of Energy Devices
Rabot Energy plans to integrate additional devices, including home batteries, electric vehicle chargers and heat pumps. Connecting these technologies could give the company greater control over when electricity is consumed or stored.
Its long term ambition is to transform separate households into a flexible energy network. Whether this model can scale successfully will depend on customer adoption, reliable automation and the economics of coordinating distributed storage. However, Rabot Energy’s latest funding gives it additional resources to pursue a future in which homes play a more active role in managing electricity demand.
