Axle Energy

Platform enabling energy asset flexibility monetization

Overview

Axle Energy provides a software platform that connects distributed home energy assets with European electricity markets. It helps energy suppliers and hardware manufacturers tap into the flexibility of assets like electric vehicles, home batteries, and heat pumps so they can participate in demand-side response and other grid services. The platform aggregates and optimizes these assets to monetize flexibility, creating new revenue streams for partners while helping lower energy costs and reduce carbon emissions for end consumers. It uses an API-driven approach with white-label solutions to simplify integration and onboarding for customers, enabling easy deployment across different markets. Axle Energy aims to support grid decarbonization and a more stable, affordable power system by expanding the use of flexible distributed energy resources in Europe.
