Energy crisis: Plan for three-hour power blackouts to prioritise heating in event of gas shortages – as EU agrees to cut electricity use
The country has been put on notice that the chances of gas shortages this winter have risen markedly, prompting a contingency plan to prioritise heating.
National Grid’s Electricity System Operator (ESO) warned that planned three-hour power blackouts could be imposed in some areas, in the “unlikely” event supplies of gas fall short of demand.
It revealed the measure in an update on the UK’s state of energy readiness for the cold months ahead but it said that the risk of temporary power cuts could be avoided with help from the public.
The report showed, under a base case scenario, that margins between peak demand and power supply were expected to be sufficient and similar to recent years thanks to secure North Sea gas supplies, imports via Norway and by ship.
It comes as EU countries formally agreed to a voluntary 10% cut in gross electricity consumption and a mandatory reduction of 5% during peak hours – in what have been labelled “extraordinary measures”.
The European Council said: “Member states will identify 10% of their peak hours between 1 December 2022 and 31 March 2023 during which they will reduce the demand.
“Member states will be free to choose the appropriate measures to reduce consumption for both targets in this period.”
The ESO urged households to help manage that balance by signing up to an energy-saving scheme through their supplier, in a bid to help ease the risk of the lights going out.
The “demand flexibility service”, due to start next month, will see bill-payers be paid to save energy during peak hours.
Coal generators, that the operator said would have otherwise closed, will be used to maintain supply. In an effort to generate enough power to supply 600,000 homes the ESO is securing contracts with three generators to keep five coal units open and on standby.
A separate study by National Grid Gas Transmission, which is a separate business to the ESO, saw the potential for the shortfall in gas supplies within continental Europe – as a result of Russia’s war in Ukraine – to impact the UK’s usual ability to attract imports.
It suggested gas needed to power the UK’s electricity grid was expected to rise by nearly 22% – offsetting savings from lower household and business use – largely because of a need for power in France where many nuclear plants are offline.
It saw LNG (liquefied natural gas) from the US and Qatar acting as the new primary source of supply flexibility.
Gas accounts for over 40% of UK power generation – more if the wind fails to blow and other plants are offline for maintenance.
The ESO’s report marked a darkening in the prospect for disruption in the months ahead following a comparatively rosy early view report in July.

Risk of emergency gas shortage
There was a clear sign of a shift in direction earlier this week when it emerged that the energy regulator Ofgem had warned of a “significant risk” of a gas supply emergency.
It blamed the international scramble for supplies because of the war, which has starved continental Europe of its main source of natural gas.
On Thursday, Prime Minister Liz Truss refused to reiterate a promise she made during the Tory leadership election that there will not be blackouts this winter.
Pushed to repeat that promise, she told reporters in Prague: “Well what we’re clear about is we do have a good supply of energy in the UK, we’re in a much better position than many other countries.
“But of course there’s always more we can do.”
A gas supply emergency can be declared when suppliers are unable to safely get gas to homes and businesses.
It could mean that some customers, starting with the largest industrial consumers, will be asked to stop using gas for a temporary period.
The aim would be to keep gas and gas-generated electricity supplies stable for households for as long as possible.
For the electricity market, coal-fired power stations can be brought back online under what is known as a system notice to help fill stopgaps. This has traditionally happened when nuclear plants go offline or the wind fails to blow.
The hope is that these sorts of measures will not be necessary because of the looming demand flexibility service.
It is expected to be implemented at least 12 times, whatever happens, from November to March to ensure a benefit for signatories.
The ESO’s director of corporate affairs, Jake Rigg, said: “If you put your washing machine or other electrical appliances on at night instead of the peak in the early evening, you can get some money back when we all need it.”
Energy bills have rocketed this year but now come under the protection of government caps on wholesale costs, shielding both households and businesses from the worst in the price surge ahead of winter.
It means the taxpayer will foot the bill for wholesale prices above the unit cap level.
The scheme does not cap your bill, which will continue to depend on the amount of energy used.
An Ofgem spokesperson said of the National Grid reports: “We have one of the most reliable energy systems in the world and we are in a favourable position.
“However, it is incumbent on a responsible and prudent energy sector to ensure the right contingency measures are in place, which is why we are working with the government, National Grid and key partners to protect consumers, so that Great Britain is fully prepared for any challenges this winter.”

‘Major incident’ declared in Northern Ireland as wildfire breaks out amid higher-than-normal temperatures
A major incident has been declared in Northern Ireland after a wildfire broke out, the latest in a series of blazes seen across the UK over the past week amid soaring temperatures.
More than 100 firefighters and 14 fire appliances were at the scene of the “significant” wildfire on Sandbank Road, Hilltown, Northern Ireland Fire and Rescue Service said.
The fire had a front of approximately two miles “including a large area of forestry close to property”, the service said.

“Local residents are requested to avoid the area, a number of roads have been closed, to help support firefighting operations,” the fire service added.
“We ask that all members of the public remain particularly vigilant to the risk of fire at this time. We can reassure members of the public that normal service delivery is being maintained.”

Various fires erupted across England this week amid uncharacteristically warm and dry conditions for the time of year.
On Saturday, helicopters were deployed to tackle Scotland’s fourth wildfire this week, with police saying a blaze “which started in the Newton Stewart area has spread northwards and is expected to reach the Loch Doon area of East Ayrshire around 12am on Sunday”.
Police Scotland added: “As a precautionary measure members of the public are asked to avoid the Loch Doon area and anyone who may be camping in the area is advised to leave.”
Moors Valley Country Park blackened by fires this week
Elsewhere in England, Devon and Cornwall Police said they were assisting the fire service with temporary road closures on the A30 in the Bolventor area as they tackle “a number of fires” on moorland.
In Dorset, Moors Valley Country Park was forced to close after multiple wildfires broke out there on Wednesday.

Wildfires spread across nature reserve
Separate incidents were then reported at Upton Heath in Poole on Wednesday, and nearby Canford Heath in the early hours of Thursday.
Friday was officially the warmest day of the year so far – with temperatures in the south of England reaching 23C (73.4F) – the highest since 21 September last year, according to the Met Office.
The weather conditions triggered a “severe” wildfire rating for parts of the UK on Tuesday.
