It operates renewable energy production projects (wind farms, hydropower plants and solar PV power plants) with an electricity production of around 30,000 MWh/year. Thanks to the skills acquired, the cooperative informs and educates citizens and municipalities on energy issues, including wind power in particular, but also the rational use of energy.

At the general meeting, all the cooperators have the right to vote on the important choices of the cooperative.
