Prior information notice issued for Irueña mini-hydro project in Spain

Spain’s Instituto para la Diversificación y Ahorro de la Energía (IDAE), a government agency tasked with promoting energy efficiency and diversification, has published a prior information notice of a forthcoming tender for the planned construction of a mini-hydropower plant at the Irueña dam in Salamanca in the central region of Castile-La Mancha.

A tender is set to be issued in the Official Journal of the European Union for the civil works and supply of equipment for the project. Plans for the installation of a hydropower plant at the toe of the existing Irueña dam, near the town of Robledo in the province of Albacete, were conceived prior to the commissioning of the dam in March 2014, with the incorporation of an intake into the dam body.

The Irueña dam, which impounds the Águeda, a tributary of the Douro River, in the autonomous community of Castile and León, regulates the river flow. In September 2020, the IDEA and La Confederación Hidrográfica del Duero (CHD), the Douro River Basin Authority, signed an agreement to jointly exploit the future power station, according to which the IDAE would finance its construction and the CHD would be responsible for securing all the necessary permits for its construction as well as for its future operation. At the time the plant was designed with two units with a capacity of around 4500 kW, and an estimated annual production of 16.3 GWh, which would provide the entire electricity supply of some 5000 households with 100 per cent renewable energy.
