Spanish power giant Endesa has brought the new Aitona small hydro plant located in the province of Lérida on stream.

The plant has installed capacity of 4.9MW and uses water discharged into the Segre river from the Seròs II hydro plant, also owned by Endesa, along the final stretch of the Catarralà ravine. The plant is included in the Seròs hidro complex that in the past was the origin of Utxesa reservoir.

The plant comprises two identical 2.45 MW semi-Kaplan turbines which permits a flow of up to 60m3/sec each, with a drop of 4.72m. Average production capacity is estimated at an annual 14.3 GWh.

Total investment in this new plant amounts to around US$7.6M.
