Central European drought and energy production impact

Severe drought and high temperatures in Central Europe have significantly impacted energy production and river levels. In Germany, the energy firm EnBW reported a sharp decline in first-half 2026 earnings, with net profit falling over 50% year-on-year. This was driven in part by reduced output from run-of-river hydro plants due to drought, alongside a planned coal phase-out. Concurrently, historic low water levels in the Rhine and Bodensee restricted shipping and prompted local authorities to impose bathing bans to protect fish.

The drought has also affected Austria, where the Austrian Power Grid reported that renewable energy production dropped by approximately 17 percent in July compared to the previous year. Specifically, run-of-river hydropower generation plummeted by 46 percent. While solar photovoltaic production rose by 54 percent, it was insufficient to fully offset the loss in hydro output, leading to an increased reliance on electricity imports. In Germany, utilities in Augsburg reported similar challenges, with hydropower generation falling roughly 30 percent below the long-term average. Despite these declines, operators have stated that energy security remains stable as fluctuations are compensated for by other generation types and the broader electricity market.
