Alliance for the development of pumped-storage hydroplants in Spain


Capital Energy and VERBUND Green Power sign strategic alliance to develop pumped-storage hydro plants in Spain.

  • Capital Energy has a significant portfolio of hydropower projects in development in Spain, while VERBUND already operates more than 130 hydro power plants (seven being pumped-storage) with an installed capacity of 8.4 GW
  • This is the second corporate agreement between Capital Energy and VERBUND in Spain, following the sale and purchase of a portfolio of wind and solar farms, with a combined capacity of 171 MW, which was sealed in 2022

Capital Energy, one of the largest renewable energy platforms in the Iberian Peninsula, and VERBUND Green Power, a subsidiary of VERBUND, Austria’s leading energy company, have signed a strategic alliance for the development of pumped hydroelectric plants in Spain. The alliance will evaluate the possible construction of two pumped-stored hydro plants in Spain with a combined capacity of about 830 MW.

Commenting on the signing, Juan José Sánchez, CEO of Capital Energy, said that "this new transaction with VERBUND, a leading European electricity company that is focused, like us, on promoting the energy transition, ratifies our commitment to the development of clean energy infrastructures, such as wind farms, photovoltaic plants or pumped-storage hydroelectric plants, which continue to promote the necessary process of decarbonization of the economy".
