The Bordes geothermal power plant was built in the early 1980s as part of the development of the heat network that currently supplies 7200 housing equivalents distributed in the municipalities of Champigny-sur-Marne and Chennevières-sur-Marne. As part of the European Heritage Days, the opening of the plant to the public will be an opportunity for visitors to familiarize themselves with the principle of geothermal energy production and the policy of the city of Champigny-sur-Marne on the development of clean energy. Any visit will be made on registration.
