National Grid has doubled its emergency planning exercises as concerns over energy shortages this winter grow.
Potential scenarios – including the rationing of electricity – will be wargamed over four days, instead of the usual two, as part of ‘Exercise Degree’.
“The aim of this exercise is to demonstrate that the gas industry is prepared and able to meet its obligations in the event of a Network Gas Supply Emergency (NGSE),” said a briefing document from the National Grid.
It will take place on the 13 and 14 of September, as well as on the 4 and 5 of October.

The annual operation, last year given the name ‘Exercise Celcius’, only took place on two days in September 2021.
National Grid said the arrangements for this year’s exercise were made back in January.

A National Grid spokesperson said: “Exercise Degree is the latest in a long series of annual exercises which go back to 1996 when the Network Emergency Co-ordinator role was created.
“The exercises enable National Grid Gas, government, and industry participants to test the effectiveness of industry-wide emergency arrangements in order to prevent, and (if unavoidable) respond to a gas supply emergency.
“The Network Emergency Coordinator has an obligation to provide assurance to the HSE on the effectiveness of these arrangements. The pre-winter exercises take place every year ahead of winter and have become a routine part of the energy industry’s annual calendar. The arrangements for Exercise Degree were made back in January 2022.”
But it comes as Number 10 insists there is no need to panic over energy supplies and said households and businesses will not face blackouts this winter thanks to supplies from Australia.
The Attalos gas tanker is set to arrive at the Isle of Grain terminal in Kent, by the mouth of the Thames, later on Monday – believed to be the first cargo of liquified natural gas (LNG) sent from Australia to Europe in six years.
The squeeze on gas supplies in Europe has helped fuel rocketing inflation and driven up household bills, with analysts expecting the energy price cap to rise to £3,554 in October.
But No 10 insisted that there was no risk to UK energy supplies and consumers should not panic.
Some of the gas on that Attalos is likely to be used in the UK straight away, but much of it will probably flow to Europe through the pipelines that connect Britain to the continent.
There it might be channeled into European gas storage sites and some of it could return to Britain during winter.

Concerns that shortages on the continent could jeopardise the supply of gas back to the UK were played down by No 10, which highlighted both North Sea production and the use of “reliable partners” such as Norway in ensuring homes could be heated and the lights kept on over the winter.
A No 10 spokeswoman said: “Households, businesses, and industry can be confident they will get the electricity and gas that they need over the winter.
“That’s because we have one of the most reliable and diverse energy systems in the world.”
She said people should not panic or feel they should cut down on energy use.

“These decisions, in terms of energy consumption, remain decisions for individuals,” she said. “But what I’m saying is that households, businesses and industry can be confident that they will have the electricity and gas that they need.”
But Downing Street has backed a plan being developed by National Grid that could see households with smart meters being paid to turn off high-energy appliances – such as washing machines – during peak times, to reduce the risk of blackouts this winter.
