Dalkia partners Métropole Européenne de Lille* to ensure a successful energy transition in the region

Heating networks in Lille and Roubaix, which Dalkia manages under an outsourcing agreement, have reached a clear watershed in the use of renewable energy and are set to significantly reduce their carbon footprint.

The Lille and Roubaix networks span more than 70 km. They supply heating and hot water to 460 buildings, including multi-dwelling units, healthcare facilities, offices and shopping centres. Annual heating consumption is equivalent to that of around 50,000 housing units.

Replacing 9,000 tonnes of coal and 190 GWh of natural gas with heat sourced from the Halluin household waste incinerator will reduce the share of fossil fuels used by 35%. Achieving this goal will require upgrades to both networks. Dalkia will carry out the work each year during the summer, with the project due for completion by the end of 2020. Dalkia's investment is backed by funding from French environment and energy management agency ADEME.

The resulting heat will be added to that already provided by biomass at the Alma site and will meet heating demand in Lille and Roubaix equivalent to that of nearly 30,000 households. The new energy mix for the Lille and Roubaix district heating networks is perfectly in line with energy transition targets and will lead to a reduction in CO2 emissions of around 75,000 tonnes a year, equivalent to taking 120,000 cars off the road in the metropolitan area.

Four million French people (6% of the population) are already connected to heating networks. The Transition for Green Growth Act introduced in France in 2015 aims to achieve a fivefold increase in the amount of renewable and recovered energy delivered through these networks by 2030. This would take the number of housing units connected to heating networks from two million today to more than eight million by 2030.
