Power sourcing

Our direct access to transportation infrastructures and wholesale markets enables us to source power for your perimeter at the best possible prices and services. We continually adjust the supply to the actual and forecasted consumption on your perimeter.


Our role as balancing operator for the power transmission and distribution networks allows us to manage your balancing constraints: we continually adjust the supply to the actual and forecasted consumption on your perimeter.

Are you developing? We integrate consumption/injection points of your new clients into our balancing perimeter. We process forecasts and actual consumption, including for profiled sites.

Do you have innovative projects? We help you optimise and benefit from your production capacities (peak load, load management) while providing you with a guarantee of available capacity.

We offer you the possibility to buy power blocks on the wholesale markets at different times and different prices, allowing you to implement a portfolio strategy.
