Our solutions in short circuit

The production in short circuits is the answer to sustainable, resilient and efficient energy, as close as possible to consumer’s needs, to be used locally.

By limiting the distance between the production of energy and its consumption, in a radius of a few kilometers, our solutions allow regions to reduce the carbon footprint related to energy consumption.

In addition, short circuits guarantee a safer supply for the regions which become less exposed to disruptions of importations.

In Hauts-de-France and in Wallonia, production of abandoned mine methane leads to avoid any emission of methane into the atmosphere, while supplying local, environmentally and economically viable energies, to the households thanks to combined heat and power units installed in various locations: electricity and local heating networks.

In Lorraine, FDE has rehabilitated a pithead in order to build the largest solar thermal plant injecting on a public district network. FDE also aims at producing the methane from the coal bearing reservoirs, to distribute it locally.

Our energies

FDE propose energies produced locally while creating value from multiple resources such as gas, sun and waste.
