    Plans for energy blackout called off.(News)


    November 29, 2022 - The Huddersfield Daily Examiner

     

      WORRIES over Britain's power supply on Monday and Tuesday evenings have been allayed as National Grid decided not to trigger an emergency plan to pay households to reduce electricity use and withdrew a warning of tight margins.

      The National Grid Electricity System Operator issued and then rapidly cancelled notice that warned of tight margins between the amount of electricity available and the amount which will be needed on Monday evenings.

      It also decided not to trigger the first live run of its Demand Flexibility Service, which pays households to reduce their electricity use and lower the strain on the grid.

      The service has been tested twice in recent weeks, and some households earned more than PS4 for taking part over the course of an hour.

      The first signs that the grid was concerned came yesterday morning at about 10am as it issued an "indication" that it might trigger the DFS for the first time today to help lower the risk of blackouts.

      It came as experts warned that the difference between supply and demand would be tighter than usual both on Monday and Tuesday evenings, not least as problems with France's nuclear fleet meant that it would be harder to import electricity from the continent.

      Then at 1.33pm the grid issued a separate warning saying that things would be tight on Monday evening at 6pm. These so-called Capacity Market Notices are automated and let electricity generators know that things are tight.

      They do not mean that blackouts are likely, just that the margins between supply and demand are smaller than the grid is comfortable with. If blackouts are considered likely then a different type of notice will be issued.

      In the last six years there have been 12 such Capacity Market Notices, all of which have been cancelled without incident.

      Sure enough, Monday's notice was withdrawn by National Grid at 2.04pm, just half an hour after being issued.

      It is unclear what changed in that time - National Grid did not immediately say - but the likelihood is that its system operators managed to find someone to supply extra electricity into the grid.

      The notices have become more common this year as Europe goes through an energy crisis because Russia shut off most of the gas that it supplies to the continent. The most recent notice was sent out last week.

      At shortly before 3pm on Monday, National Grid said that it no longer thought it would be necessary to ask households to reduce their power use on Tuesday evening.

      Millions of people around the country will be settling in to watch England play Wales at 7pm tonight in the teams' final game in the group stages of the World Cup.

      France has been facing months of problems with its nuclear power plants, which generate around three quarters of the country's electricity. More than half of the nuclear reactors run by state energy company EDF have closed due to maintenance problems and technical issues.
