Voltalis

About

Founded in 2006, Voltalis is a private headquartered in Paris, France specializing in Energy Storage.

Voltalis is a French company founded in 2006 that specializes in intelligent electric heating management and demand-side flexibility. The core offering is a free smart thermostat system installed on electric radiators and heat pumps, connected via a proprietary platform. The technology performs brief, imperceptible load reductions during peak grid demand, helping balance the electrical system without compromising user comfort. Voltalis aggregates flexibility from over 250,000 equipped households across Europe to stabilize the grid, reduce reliance on polluting thermal power plants, and facilitate renewable energy integration. The company is remunerated by the electrical system for these grid services, enabling it to offer installation and service entirely free to residential users. Voltalis is officially qualified by RTE (the French transmission system operator) since 2008 as a residential demand response aggregator. The company is majority-owned by Meridiam, a specialist in infrastructure financing for energy transition.
