PARIS, Dec 6 (Reuters) - Nuclear power generation in France plunged nearly 11 % year-on-year in November to 29.1 terawatt hour (TWh) state-controlled utility EDF said on Friday, citing a high volume of reactor outages.
Total output since the start of the year was at 346.5 TWh, down 2.2% compared with the same period last year, the company said.
The utility, which operates France’s 58 reactors that cover around 75% of French power needs, cut its 2019 nuclear production target on Nov.14 to between 384 TWh and 388 TWh from 390 TWh, due to prolonged outages of its reactors.
The slump in generation could see EDF miss the revised target with several reactors still offline for extended scheduled maintenance or safety checks.
Available nuclear capacity in France was at 71.4% of the installed maximum on Friday, with 17 reactors offline according to Reuters table.
Among the reactors that are offline due to an unplanned shutdowns are four at the 3,600 megawatts Cruas nuclear power plant, where French nuclear watchdog ASN is carrying out a safety probe following an earthquake.
EDF said that in Britain, nuclear power generation from its reactors surged 9.3% to 4.7 TWh in November due to the recent restart of some reactors.
Total output in Britain since the start of the year was at 46.3 TWh, down 14.7% compared with the same period a year ago. (Reporting by Bate Felix Editing by Geert De Clercq and Louise Heavens)
