Andorra la Vella has the first turbine that transforms water pressure into energy. It is installed in the Escaubelles water tank and is one of the community’s efforts to make the community a more sustainable place.

Andorra la Vella will stop emitting 23 tonnes of CO2 per year with the Perga microturbine. Installed in the Escaubelles water tank, it lowers the pressure of the water coming from the Cornella and generates 90,000 kilowatts of energy per hour every year. This is enough energy to power two residential buildings. It is also the first installation of its kind in the country, and has been implemented by Perga technology, of which Alisea is a partner.

The vice-mayor of Andorra la Vella, David Astrié, explained that the estimated cost of the project is between approximately 130,000 and 140,000 euros and the forecast is that “it will save between 7,000 and 8,000 euros a year with this installation”.

It has been producing at full capacity for 15 days and works 24 hours a day and practically 365 days a year. The Escaubelles water tank has a capacity of 4,300 cubic metres and supplies water to a large part of the community.
