Between 2016 and 2018, Eco Delta successfully developed and sold two ready-to-build wind projects in the north of France — Arville and Fontaine-la-Guyon — totaling 25 MW. These projects reflect Eco Delta’s commitment to advancing clean energy and sustainable land use through thoughtful, regionally integrated development.
In line with its mission to promote renewable energy across Europe, Eco Delta finalized the sale of two wind energy projects in northern France between 2016 and 2018. Together, the Arville and Fontaine-la-Guyon wind parks contribute 25 MW of clean, sustainable energy to the French grid.
Arville Wind Project – 12 MW
Located in Seine-et-Marne (77) on the Gâtinais Beauceron plateau, just 70 km south of Paris, the Arville wind project embodies Eco Delta’s ability to develop impactful projects close to major population centers while preserving rural character. The original park, sold to Leonidas Associates GmbH in 2017, includes six Vestas V90 turbines, delivering a total installed capacity of 12 MW — enough to power a city of 12,000 residents.
Eco Delta also led the development of Gâtinais III, an extension that adds three additional turbines. The project was revised in collaboration with the French Directorate General of Civil Aviation (DGAC) due to its proximity to the Mondreville ULM airfield, receiving a favorable opinion in September 2019. A complementary prefectural decree was issued in March 2024, reflecting updates to environmental regulations under France’s ICPE framework.
Designed with care for its surroundings, the park is located in a sparsely populated agricultural area and incorporates visual impact simulations to ensure proper landscape integration. The project supports the regional wind strategy of Île-de-France, which currently includes 42 turbines across seven wind parks.
Fontaine-la-Guyon Wind Project – 13.2 MW
Developed by Eco Delta and sold to EDF Renewables, the Fontaine-la-Guyon project is located in Eure-et-Loir (28). This land-based wind park includes six Vestas V100 turbines, each with a capacity of 2.2 MW, for a total of 13.2 MW.
The project was guided by thorough environmental monitoring, particularly regarding avifauna. Observations during the operational phase confirmed minimal ecological disturbance, with some species exhibiting avoidant behavior in proximity to the turbines. A prefectural decree in May 2017 authorized the construction of a dedicated electrical network to connect the turbines to the delivery station.
