Dalkia as industrial company in France

Dalkia is a part of the EDF Group and is currently operating hundreds of energy plants in France and with other activities in the remaining Europe and USA. They currently operate more than 350 district heating and cooling networks supplying heat to the equivalent of more than 2 million households.

Dalkia is responsible for a large-scale expansion of the district heating network in the city of Rouen. Part of this upgrade is the installation of new heat generation capacity. The heating plant will be based on the Dall Energy gasification technology in order to comply with the city’s requirement for reducing its environmental footprint for non-ETS sectors (sectors not quota regulated via the EU Emissions Trading System). The plant is designed to operate on local biomass of various qualities which will be sourced locally.



Base load heating plant

Our scope includes a furnace and boiler being designed to supply up to 17 MW of heat for more than 7000 operation hours per year and will be a base load heating plant in the local district heating network. As the network has no accumulation tanks the plant shall adjust the heat output according to any alternations in the heat demand.


Construction ongoing

Design and construction

The furnace design started in Q4 2018 under a pre-engineering agreement. As per March 2019 the design, procurement and construction are ongoing according to the project time schedule.

The scope of Dall Energy comprises biomass gasification furnace and hot water boiler including all associated auxiliary equipment e.g. fans, piping, switchboards, fuel feeding system and ash handling system. Dall Energy is responsible for turnkey delivery of the equipment including design, procurement, installation and commissioning.

This project has received funding from the European Union’s Horizon 2020 Research and Innovation Programme under Grant Agreement no. 811529.
