Poland Vistula water shortage and energy cuts

In late July, researchers, NGOs and local activists highlighted severe water loss in Warsaw’s Jeziorko Czerniakowskie lake and warned that the Vistula River near Kozienice was facing a complex set of stressors, including climate‑driven drought, energy‑sector water use and invasive species. They called for external water replenishment and a holistic assessment of ecological impacts.

A week later, a pronounced drought across Europe had reduced the Vistula’s flow to just 135 m³/s, prompting Poland’s energy provider Enea to curtail output at the Kozienice and Połaniec coal‑fired power stations by about 1.3 GW. The cut, enough to power over a million households, underscored how the river’s low water levels directly affected national electricity generation. Environmental groups linked the water scarcity to threats for protected fish larvae and criticized plans for new gas capacity, urging a faster transition to clean energy.

Together, the snapshots trace the shift from early scientific and activist warnings about water depletion to concrete operational consequences for Poland’s power sector, illustrating the growing interplay between climate‑induced water scarcity and energy security.
