Paris, February 12th – Kyotherm, Omnes Capital, Cofely Réseaux and Storengy team up for the design, construction, financing and operation of the geothermal heating network of the future eco-touristic destination Villages Nature.

By teaming up with robust financial partners and renowned experts in the field of geothermal energy, Villages Nature will benefit from a renewable energy that stems from a local source in the undergrounds of Marne-la-Vallée: an energy solution that is ecological, innovative as well as consistent with the ambitions of the Villages Nature project in terms of sustainable territorial development.

A renowned group of experts with complementary know-hows

The four partners have created a dedicated company – Société Géothermale de Val d’Europe – in order to build and operate the geothermal heating network under a 25-years concession agreement.

Main investors are Omnes Capital and Kyotherm, with Kyotherm managing the dedicated company. Both actors have provided equity to the project, and are supported by long-term investors that are sensitive to the challenges of sustainable development and of the energy transition. The total cost for building the heating network and the geothermal plant amounts to €41.3m.

Cofely Réseaux and Storengy, both GDF Suez subsidiaries, are minority shareholders in the company. Cofely Réseaux is in charge of the design, the construction and the operation of the geothermal doublet and the heating network. Cofely Réseaux relies for that on Storengy’s expertise in the field of underground operations.

A 100% renewable energy solution

The four partners will provide Villages Nature with a 100% local and renewable energy solution that meets the ambition of this unique eco-touristic destination. The supply of geothermal energy to Villages Nature consists in extracting water at 76 degrees from a 1,25 miles deep aquifer cavity. Brought up by the production well, the geothermal heat will be distributed according to a precise distribution network designed for a sustainable use that limits thermal losses. The geothermal heat will first cover the heating and hot sanitary water demand from all flats, cottages as well as entertainment installations. The residual heat, which temperature will then have reduced to approx. 30 degrees, will supply the Aqualagon, a 9 000 m² covered water park, as well as its 2 500 m² external lagoon, and will eventually be restituted to its natural environment through the injection well.

The use of geothermal energy, a clean energy that does not emit any greenhouse gases, will allow to avoid the release of 9 000 tons of CO2 per year in the atmosphere.

Commissioning of the heating network and geothermal plant in 2016

  • July 2014 – Summer 2016: construction phase
    • Preparation of the drilling site
    • Drilling on the 1 800 meter deep Dogger aquifer
    • Construction of the 18km heating network
    • Construction of the building for the geothermal plant
  • Summer 2016: commissioning of the 18km heating network and of the 13.5 MW geothermal plant

Arnaud Susplugas, CEO of Kyotherm and of Société Géothermale de Val d’Europe: This geothermal heating network project in Marne-la-Vallée is the proof that producing renewable energy can be economically competitive. The cost of capital usually represents over 50% of the global cost of a renewable MWh. Resorting to project financing for these energy infrastructures has allowed to obtain a very attractive cost of capital. In the end, the price of the renewable MWh is competitive compared to fossil energies, which corresponds to Kyotherm’s ambition and vision.
