The summer stress test: How heat waves are rewiring Europe's power markets
About this episode
This episode discusses how rising summer temperatures and heat waves are fundamentally changing Europe's power markets and infrastructure planning.
Traditionally, European power systems were engineered around a single imperative: survive the winter "Dunkelflaute," those prolonged cold, dark, windless stretches that push demand higher while renewable generation collapses. But rising summer temperatures are dismantling this assumption. Heat waves are forcing a fundamental recalibration of infrastructure investment, operational strategy and market design across the European power sector. In this episode, host Eklavya Gupte speaks with Parth Goel , power analyst at S&P Global Energy CERA, about how extreme heat is reshaping demand patterns, straining supply and exposing vulnerabilities in the continent's energy infrastructure. Goel explains why France, not Southern Europe, has emerged as the most price-sensitive region during heat waves, how solar generation creates dramatic price swings between midday troughs and evening peaks, and why Europe is shifting from a winter-peaking power system to a dual-peaking one. The conversation also examines the compounding effects of drought on Alpine hydro, the thermal stress on nuclear cooling systems, and why summer now demands the same infrastructure planning attention as winter.
