The VALOREM Group has launched construction of the Granges wind farm in the municipality of Saint-Quentin-sur-Coole.
The Granges wind farm project was acquired by the VALOREM Group in 2025, thanks to its ability to connect the farm to the national electricity grid at its high-voltage substation in Fagnières.
Carried out by VALREA (VALOREM’s construction subsidiary), the project required an investment of €20 million. It began on 13 January with the creation of the site base, access roads and platforms to accommodate the farm’s five wind turbines. The VALOREM Group is making maximum use of local companies. For example, the Marne-based company POTHELET has been called upon for this roadworks and utilities work.
Designed with local environmental issues in mind, the construction schedule includes a break in work between April and August 2026 so as not to disturb the birds’ nesting periods. In addition, throughout the wind turbines’ operating life, the VALOREM Group has commissioned the local cooperative Sun Déshy to maintain 6 hectares of alfalfa, thus creating areas that attract biodiversity, particularly populations of hen harriers, a protected species in France.
The wind turbines will be assembled as they arrive on site, starting in January 2027, and will then be commissioned in spring 2027.
The construction of this wind farm is very good news at a time when the renewable energy sector is suffering from a lack of visibility in terms of energy policy. For several months now, it has been awaiting the publication of the Multi-Year Energy Programme (PPE), a document that sets out the framework for the development of renewable energies over the coming years, making project planning and investment decisions more complex. However, in the face of the climate emergency, our abundant and competitive renewable electricity production is a major asset for the economic dynamism of our regions, accelerating the decarbonisation and reindustrialisation of our country!
The Granges wind farm consists of five 2 MW wind turbines, each with a blade tip height of 130 metres. It will produce an average of 30 GWh per year, equivalent to 25% of the electricity needs of the Moivre à la Coole Community of Municipalities.
It strengthens VALOREM’s presence in the Marne, a historic wind energy region in France where the Group has been active for over 20 years, making a lasting contribution to the regional energy transition.
