Heating entire neighborhoods using unused steam discharge from the Sarpi company at the port of Limay (Yvelines). This is the ambition of the Grand Paris Seine & Oise urban community (GPS&O) to supporting the energy transition.
“The public service delegation, granted to the Mantaise Heating Operation Company (Somec), arrives ends in 2026explains Yann Perron, mayor of Gargenville and vice-president of GPS&O responsible for Energy and the Seine Axis. It was 65 years old, it was necessary to start again on a project more in line with current issues. »
Vote on the principle of extension
The community council therefore voted, in June 2024, in favor of the principle of extending the urban heat networktoday supplying 5,500 homes and several public facilities in the Mantais district of Val Fourré, as well as its connection to the Sarpi special industrial waste incineration plant.
“The goal is to initially power the city center of Mantes-la-Jolie and Limay with 75% renewable energy. »
“The district heating network would operate by recovering waste heat from Sarpi (heat resulting from an industrial process or incineration whose primary objective is not the production of energy and which is usually released into the air ambient through large chimneys – Editor’s note), also informs the vice-president of GPS&O. In addition, the boiler room would run gas up to 25%wood would only be a complement. »
Heavy work required
Interested individuals residing in Mantes-la-Ville could be connected to the network created in a second phase. “This ecological solution makes it possible to guarantee a stable price energy. », continues Yann Perron.
“In the medium term, if the quantity of heat recovered is large enough, a reduction in cost is even possible. »
The project is now entering its operational phase. “A new public market will be launched,” announces the mayor of Gargenville. The selected operator will be responsible for deploying the network extension and find customers in order to economically balance the operation. »
Major works are coming. “We will favor the areas where there are already networkssuch as railway tracks or the banks of the Seine, in order to limit their impact,” promises Yann Perron.
Contacted, the subsidiary of Veolia did not wish to answer our questions.
A model to duplicate?
Convinced of ecological and economic virtues of the process, the vice-president of GPS&O responsible for Energy would like to duplicate it. “The Carrières-sous-Poissy incinerator is the property of the urban community,” explains Yann Perron. Almost all GPS&O waste is already processed there. »
From this site, the elected official assures that a district heating network could be created to supply the municipalities of Carrières-sous-Poissy and Poissy, as well as the car manufacturer premises Stellar
“Secondly, the commune of Chanteloup-les-Vignes could be associated at the end of its public service delegationin 2035, anticipates Yann Perron. A complete study with all the technical elements of this achievement is to come. »
