Spanish hydropower dams are on course to end the summer at their lowest level in three decades, putting more pressure on electricity costs as Europe’s energy crisis widens. 

Hydro capacity stood at 36.9% in the week through Aug. 23, the lowest since 1995, according to data published by the energy ministry. Reserves are also significantly below the 10-year median.
