Octopus Energy, a UK-based energy company, is launching a unique housing project in Guichen-Pont-Réan, south of Rennes, France. The project involves building 100 homes where residents will not have to pay electricity bills for 10 years. This initiative is part of a larger plan that could be expanded across France. The homes will be equipped with advanced energy-saving technologies, including thermal insulation, heat pumps, solar panels, and domestic batteries. These features are designed to allow residents to generate and store their own electricity, and the entire system will be managed remotely by Octopus Energy to optimize energy use and recharging based on real-time electricity prices. The construction will take place on the Massaye estate, a historic site that was once popular with urban explorers. The estate includes a castle built in 1630, which had been abandoned for nearly 20 years. Now, the area will be transformed into a modern community that includes not only the 100 timber-framed houses but also professional activities and local services. This project aims to blend historical architecture with contemporary, sustainable living. The homes will range in price from 75,000 to 311,000 euros. Construction is expected to begin in the first quarter of 2027, with the first homes set to be delivered in early 2028. Octopus Energy plans to expand this initiative by forming partnerships with real estate developers and local authorities, with the goal of creating 15,000 "Zero Bills Homes" by 2030. It is important to note that the zero electricity bill offer does not include the use of electric cars. Octopus Energy has mentioned that if residents exceed a certain electricity consumption threshold, they will be billed for the surplus electricity they use. However, the company has not specified what this exact threshold will be.
