Rabot Energy Raises $50M for Virtual Power Plants

German energytech Rabot Energy has raised $50 million to expand dynamic electricity tariffs and connect household energy devices into a virtual power plant.

What happened

The Series B was led by Endeit and the DeepTech & Climate Fonds, with participation from existing investors including HV Capital, HTGF and Bosch Ventures. Rabot offers dynamic electricity tariffs that automatically shift consumption toward lower-price periods. It is also connecting home batteries, EV chargers and heat pumps so their combined demand can be coordinated. The company reports more than 200,000 customers, including around 15,000 commercial and industrial users, and €200 million in revenue. Those operating figures are company-reported.

Why it matters

Renewable power creates periods when electricity is abundant and cheap, but household demand does not always occur at the same time. Coordinating thousands of batteries, chargers and heat pumps allows them to absorb electricity when supply is high and reduce usage when the grid is constrained. That can lower customer bills while providing flexibility to the power system.

The bigger picture

Virtual power plants turn distributed consumer hardware into grid infrastructure. As electrification increases, software that orchestrates flexible demand could become a major part of the energy stack. Rabot's long-term value will depend on device integration, customer retention and whether it can monetise flexibility across different electricity markets.
