Key insights
- French power prices surged due to heatwave concerns about nuclear reactor curtailments and reduced hydroelectric availability. Disruptions in France's nuclear fleet, a key part of Europe's power market, impact electricity prices across the region. Rising river temperatures, particularly in the Rhône, exacerbate the situation. This could lead to higher energy costs for European businesses, indirectly affecting US companies with European operations.
Investing.com -- French power prices surged on Tuesday as scorching summer temperatures raised concerns about potential nuclear curtailments and reduced hydroelectric availability.
Month-ahead prices jumped as much as 11.7% to the highest level since late March, according to data from EEX.
Northwest Europe is experiencing the first heat wave of the summer, with daytime temperatures in Paris expected to reach 33C on Tuesday. Hot summers have previously forced French nuclear reactors to halt operations when river water temperatures used for cooling became too high. Last year, coastal reactors faced disruptions when marine heat waves caused jellyfish to clog filter drums.
France’s nuclear fleet serves as the backbone of Europe’s power market, with changes in output affecting electricity prices domestically and across the wider region.
Water temperatures in the Rhône are rising sharply. In Geneva, the river reached a May record of 21.3C this weekend, up from 13C a week earlier, according to Swiss authorities.
French month-ahead prices were trading 8.7% higher at €33.65 per megawatt-hour at 12:00 p.m. local time. The contract for the third quarter rose as much as 6.1%. German front-month prices, Europe’s biggest market, rose as much as 6.2%.
