Spain’s hydropower generation capacity last week dropped to the lowest in almost five years at the same time as the country braces for a drier-than-usual Autumn following the hottest summer on record. 

The capacity to generate power using water was at 6,426 gigawatt-hours last week, or 27.9% of the total, according to the Ecological Transition Ministry. The drop is due to scorching heat and the lack of rain during the summer, the driest on record, with water reservoirs overall at the lowest level since 1995, according to Bloomberg calculations based on the ministry’s data.
