Delta Green partners with utilities to monetize residential batteries and EVs during negative electricity price spikes
Type: Partnership · Technology: Storage · Country: Germany · Announced: 2026-05-05
Czech company Delta Green has established partnerships with established utilities like E.ON to aggregate distributed residential assets—including batteries, electric vehicles, and wallboxes—into a virtual power plant for flexibility services. The model enables utilities to reduce price and balancing risks while generating additional revenue for customers through intelligent control systems that optimize consumption during negative wholesale price periods. On May 1, 2026, Delta Green-managed households in Germany earned €30 to €40 in a single day by strategically charging batteries and EVs during negative price spikes, demonstrating the financial viability of the approach. The company operates under a 'flexibility-as-a-service' model, providing software solutions without aiming to become a large utility itself. Delta Green's platform forecasts wholesale prices over a 72-hour horizon and coordinates flexible assets to maximize grid consumption when prices are negative, turning conventional home energy management on its head.
