Sunday demand to drop to 13.8GW, National Grid seeks more footroom. National Grid ESO expects demand on the transmission system to hit a new low this weekend and will likely need to call on its new footroom service as well as other tools to keep the power system stable. The ESO forecasts demand to fall to 14GW Saturday night and 13.8GW on overnight Sunday. Daytime demand on Saturday of around 15.6GW, with almost 10GW of distributed wind and solar generation anticipated, could prove more challenging. The ESO hopes to sign up more footroom providers this week to help it balance the system by either consuming more power or curtailing export. The ESO said to date, some 2.4GW across 170 units has signed up to its Optional Downward Flexibility Management (ODFM) service, launched earlier this month. It used 238MW of ODFM in the early hours of 10 May as demand dropped below comfortable limits.

New measures to keep the lights on as the pandemic takes its toll on electricity demand will cost about £500 million this summer, National Grid estimates. The costs, including paying surplus power plants to switch off, will be passed on ultimately to homes and businesses through their energy bills. This weekend National Grid is preparing to use the measures when demand is forecast to fall to record lows, threatening to leave the system overwhelmed with too much electricity. Yesterday power prices for this weekend were already negative as traders sought to offload surplus electricity. Octopus Energy said that it would pay 100,000 customers with smart meters to use power. Under a trial, it will pay a household about 10p per hour to use their washing machine between 5am and 7am on Sunday, compared with usual charges of about 30p an hour. National Grid’s control room has to keep electricity supply and demand balanced in real time to prevent blackouts. The lockdown has led to a drop of about 20 per cent in demand as businesses stay closed. EDF’s Sizewell B nuclear plant will be paid more than £50 million to run at half its normal output this summer, freeing up space on the system for more flexible plants. National Grid is also preparing to pay dozens of small wind and solar farms to switch off.

Hundreds of renewable energy projects may be asked to turn off this weekend to avoid overloading the grid as the UK’s electricity demand plummets to record lows. Britain’s demand for electricity is forecast to tumble to a fifth below normal levels due to the spring bank holiday and the shutdown of shops, bars and restaurants mandated by the coronavirus lockdown. National Grid is braced for electricity demand to fall to 15.6GW on Saturday afternoon – a level usually associated with the middle of the night – and continue to drop even lower in the early hours of Sunday morning. Meanwhile, the sunny weather is expected to generate more renewable electricity than the UK needs. “Bank holidays see reduced demand for electricity, and even more so with the current lockdown measures in place,” said Amy Weltevreden, a manager at the energy system operator.

Renewable energy sources have provided more electricity in the UK than fossil fuels for the first time. The analysis, produced by Imperial College London and the energy company Drax, covers the first three months of 2020 and follows last year’s progress on clean energy projects which had them eclipse fossil fuels as renewable energy capacity levels hit a record high.
