Overview
Parc éolien de l'Hyrôme (also known as Parc éolien citoyen de l'Hyrôme) is a citizen-owned wind energy project located in the commune of Chemillé en Anjou, in the Maine-et-Loire department of western France. The project is led by the association AtoutVent en Chemillois, a local collective founded in 2011 with the goal of investing collectively in a wind farm. The Hyrôme wind farm is situated across the delegated communes of Chanzeaux and Valanjou, within the territory of Mauges communauté. The project follows the earlier successful citizen wind farm project of La Jacterie, which served as a model for renewing the operation. The association acquired the Hyrôme wind farm on 28 February 2019, and as of the official website's last update, the project was in its construction phase. The initiative is supported by Mauges communauté, which is considering investing alongside the citizens, and by Énergie Partagée, a national association promoting citizen-led renewable energy. The wind farm is a product brand representing a specific renewable energy installation rather than a manufacturing or retail company. Its core purpose is to keep the economic benefits of wind energy production within the local territory rather than allowing them to accrue to outside investors. The project embodies values of sharing and collective action for territorial development. As a citizen energy project, it opens its capital predominantly to collective financing and its governance to local actors, in line with the definition of 'citizen' energy projects promoted by Énergie Partagée.
History
The Parc éolien de l'Hyrôme is a citizen wind energy project in the Chemillé en Anjou area of Maine-et-Loire, France. Its origins lie with the association AtoutVent en Chemillois, created in 2011 with the objective of investing collectively in a wind farm. The association's values are sharing and collective action for the dynamics of the territory. The project follows the success of an earlier citizen wind farm, the Projet de La Jacterie, which demonstrated that local residents could acquire and operate a wind farm. Building on that experience, AtoutVent en Chemillois sought to renew the operation with a new project on the communes of Chanzeaux and Valanjou. The association was able to acquire the Hyrôme wind farm on 28 February 2019. Following the acquisition, the project entered its construction phase. The wind farm is located on the commune of Chemillé en Anjou, straddling the delegated communes of Chanzeaux and Valanjou. The project is supported by Mauges communauté, which is reflecting on its involvement as a local authority in renewable energy development and is accompanying the acquisition project with a view to possibly investing alongside the citizens. It is also supported by Énergie Partagée, a national association that promotes citizen energy. According to Énergie Partagée, a 'citizen' project is one that opens its capital predominantly to collective financing and its governance to local actors. The Hyrôme project aims to ensure that the economic benefits of operating the wind farm accrue to the inhabitants of the territory rather than to outside investors. As of the official website's content, the project was in the construction phase, with the acquisition completed in 2019.
