Gas plant in France at risk of failure due to high temperatures

The Mediterranean Sea's high temperatures, which have limited the availability of cooling water for gas plants in southern France, could lead to a gas plant going offline on Thursday evening. This would add further pressure to an energy system that is already under stress due to reduced nuclear output.

Early summer heatwaves have caused temperatures to rise to unheard of levels in Europe, leading water shortages, fires and even deaths.

The French utility EDF has issued a?restriction? notice for its 930 megawatt Martigues power plant. This is the first time in this summer that an electricity plant powered by gas could be?at-risk of being shut down due to heat.

EDF said that an exemption had been granted for the gas plant to continue operating beyond the normal threshold of 30 degrees Celsius (86 degrees Fahrenheit). This was until September 15th, but the extended limit was already at risk.

Due to high river temperatures, the outage will add to the 4.9 Gigawatts of nuclear?capacity that was unavailable on Thursday evening. A further 2.5 GW of nuclear capacity is unavailable due to low river levels.

Temperatures are expected to fall, but the drought is worsening

The French energy mix is dominated by nuclear power, which accounts for about 70% of total energy supply. About 14% of France’s total capacity is affected by the nuclear outages.

Thibault Laconde is the founder of Callendar Climate Data Analytics. "We've seen two waves in climate-related outages that were unprecedented?in severity and timing.

Due to high temperatures on Friday, additional nuclear reactors will regulate their output. Meanwhile, an outage at 'the Bugey 3' reactor is expected to be resolved on Friday evening when temperatures begin to cool.

The heat-related outage at Golfech 2 in southern France should end by July 25.

Low water levels in the Meuse River, which is part of a water sharing agreement with Belgium, have forced the Chooz plant to shut down around 2.5 GW.

MeteoFrance has said that the heatwave in France is likely to continue to recede over the next few days. By the weekend, the high temperatures are expected to be confined mainly to the southeast.

It added that the drought had worsened every day since May due to a lack of rainfall and exceptionally high temperatures. Reporting by Forrest Crellin, Editing by Nina Chestney Joe Bavier Jan Harvey
