Voltalis, smart electricity 'boxes'

Optimization of residential and commercial electricity consumption, using individual smart “boxes” which dynamically control user demand, generating savings and reselling surplus



Created in 2006, Voltalis is a European leader in demand-response. It is one of the European pioneers in an innovative energy efficiency solution enabling to manage electricity demand (primarily for heating, air conditioning and EV charging) of residential (individual and collective, including through social landlords) and commercial buildings.

Their energy-saving solutions already equip more than 100,000 homes and make the electricity consumption of private individuals and companies more flexible and controllable, notably to the benefit of power system optimization and ecological transition.

Voltalis optimizes the residential and commercial electricity consumption using individual smart “boxes” which dynamically control the actual users’ demand. This technology generates savings on the users’ electricity bill, and supports the balancing of the energy grid, by reselling the used electricity capacity in peak hours. Voltalis, through its demand-side management activities, plays an instrumental role in the stability and security of the electricity grid (e.g. preventing blackouts) and actively contributes to the ecological transition by providing a decarbonized solutions to peak electricity demand management. It supports the transition to an increasing share of renewable energy that calls for an increased need to balance electricity generation and consumption in real time.

Meridiam’s cooperation with Voltalis started in 2018.
