Concerns for Britain's energy supply when Wales play England at World Cup

Concerns have been raised over Britain's energy supply on the evening Wales play England at the football World Cup.

National Grid issued two separate indications that things could get tight on the evenings of both Monday (November 28) and Tuesday (November 29).

Millions of people around the country will be settling in to watch Wales and England at 7pm on Tuesday in the teams' final game in the group stages of the World Cup, with Rob Page's men hoping results go their way to progress to the knockouts while Gareth Southgate's team want to finish top of the group.

As for fans watching from back home, the National Grid Electricity System Operator issued and then rapidly cancelled a notice that the difference between the amount of electricity available and the supply of electricity would be smaller than hoped for on Monday evening. It comes as the grid will struggle to rely on nuclear power coming from France, where supply will also be tighter than usual on Monday and Tuesday evenings.

The so-called Capacity Market Notice was issued at 1.33pm, with a warning of a tight grid at 6pm. The notice was cancelled again at 2.04pm. The alerts are sent out automatically when expected margins drop below a certain level. They do not mean that blackouts are likely.

All 12 capacity market notices that the grid has put out have been cancelled without issue in the last six years. The notices have become more common this year as Europe goes through an energy crisis. The most recent notice was sent out last week.

It came as National Grid said earlier on Monday that it was considering whether to pay households across Britain to reduce their energy use to help out on Tuesday evening.

The ESO said it was contemplating whether to activate the first ever live run of its Demand Flexibility Service - which is designed to avoid blackouts. It works by asking households to reduce the amount of electricity they use at certain times - and promises to pay them for any reductions they make. The scheme was launched earlier this month and has already been tested twice but has not yet run live.

It comes as forecasts projected a large drop in the amount of power that Britain will be able to import from France. It will mean that the difference between the amount of electricity available for households and businesses and the amount they will use during peak times will be tight.

"Even though wind is coming back for tomorrow [Tuesday] evening's peak, slow return of nukes in France plus lower temperatures may mean that there is a reduction in available imports across the interconnectors," according to consultancy service EnergyAppSys.

The forecasters also warned that margins will be tight in both Britain and France on Monday evening, meaning both countries will need to import power from abroad. 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. It has added to a massive energy crisis in Europe as the country faces a winter without its old gas supplier Russia.

National Grid said that it would decide by 2.30pm on Monday whether to activate the Demand Flexibility Service.

"An anticipated DFS requirement notice has been published for tomorrow, Tuesday," it said. "This is an indication that a DFS service requirement might be published today at 2.30pm."

The system has been tested twice since it was launched a month ago. During both tests businesses and households banded together to reduce demand by a small but significant amount.

So far Octopus Energy is by far the most active energy supplier in the Demand Flexibility Service. It released data showing that its customers had helped reduce demand by more than 100 megawatts during both tests. That is the same amount of electricity that a small power plant produces.

So far not many suppliers are taking part but National Grid hopes that participation will increase in the weeks ahead.
