National Grid Agrees 6-Week Deal to Cut EDF’s Sizewell Nuclear Power
(Bloomberg) -- National Grid Plc held talks with Electricite de France SA about temporary supply curbs at its Sizewell nuclear plant, but discussions ended with no agreement.
Last year, the U.K. grid operator paid Sizewell to turn down to help balance the grid when demand was low due to pandemic-related lockdowns. Discussions this year included conversations with companies involved in measures taken last summer to manage the reduced power demand, National Grid said in a statement.
These conversations weren’t formal and National Grid has “not signed a commercial agreement with EDF to turn down output of Sizewell this summer. We do not expect to need to sign a similar agreement in 2021,” the company said in the statement.
Demand usually starts to drop in spring and is at its lowest in summer. Blackouts can happen when there’s too much demand or too little. National Grid needs ways to cope with such low demand on the network especially when it’s happening at the same time as high wind or solar levels.
Both units at EDF’s Sizewell plant are scheduled to be halted for planned maintenance for about 6 weeks through the end of May, according to the company’s transparency website.
(An earlier version of this story was corrected to show that talks are ongoing, but that no deal has been reached.)
