Rabot Energy secures $50M to transform homes into a virtual power plant

Rabot Energy has brought in $50 million in Series B funding as it pushes deeper into the idea that households can help run the grid, not just draw from it. The round was led by Endeit and the DeepTech & Climate Fonds, with support from existing backers including HV Capital, High-Tech Gründerfonds, Bosch Ventures, CNI, Acurio Ventures and vent.io.

The company’s core product is a dynamic electricity tariff that nudges consumption toward cheaper periods when renewable power is more available. It also links with home batteries, so electricity can be stored when generation is high and released later when supply is tighter. That is the real bet here: flexible demand, spread across many homes, can do some of the work that used to fall to bulky central infrastructure.

Rabot is already selling that idea through Rabot Flow, launched in June 2026. The package combines a dynamic tariff, a smart meter and a plug-and-play home battery, and the company says it can cut household energy costs by 15 per cent. The battery plugs into a standard socket, does not require rooftop solar and can be used by renters, which broadens the pitch beyond the usual owner-occupier crowd.

The next step is bigger still. Rabot is building a virtual power plant model that would coordinate connected home batteries across households, along with other devices such as electric vehicle chargers and heat pumps. In the company’s telling, the future power plant is not a single site but a network. That is also the logic behind its growth targets: Rabot says it has passed 200,000 customers in a little over three and a half years, including about 15,000 commercial and industrial clients, generated €200 million in revenue, and now wants to reach one million customers.
