The heating network for the Greater Poitiers urban community—which Dalkia has managed since 2009—is 69% supplied by local renewable and recovered energy sources from the Poitiers waste-to-energy facility, the Couronneries wood-fired heating plant and the brand new straw-fired heating plant in the Dolmen district. In two years, the network has doubled in size from 15 km to over 30 km, extending to the south-east of the city. Poitiers University Hospital took advantage of this extension to connect to the heating network and benefit from locally sourced clean energy.
The 2,800 kW connection will reduce CO2 emissions from the teaching hospital by 2,000 tonnes, equivalent to taking 1,111 cars off the road each year. Heat was previously generated by several systems using geothermal energy, heat pumps and gas. The new connection provides an alternative to the hospital's fossil fuels and adds 50% to the existing clean energy system.
