Operator says UK power grid may face lowest demand ever this summer

The National Energy System Operator (NESO), which is responsible for the UK's electricity grid, said that the National Energy System Operator expects the power grid to be well-supplied this summer due to the renewable energy generation and the cheap imports of power from Europe.

In its summer outlook for April to October, NESO stated that the electricity transmission network may need to operate below its lowest level ever at certain points. This would be less than June 2020, when COVID-19 lockdowns reduced electricity demand to below summer normal levels.

The peak demand for electricity is expected to be 29,7 GW in the summer.

Solar power production has already reached record levels in March and April this year. At 12,68 GW it is more than Britain’s total import capability from interconnectors to Europe.

The report stated that Britain will also benefit from the importation of power from Europe in the summer, due to the availability of conventional power plants.

The NESO must ensure that the grid receives a minimum amount of electricity to maintain balance.

In its report, NESO stated that it expects to have enough supply to meet the demand and operational reserves requirements for all of this summer.

The company said that the tools were in place to manage its network during times of low demand. These included Negative Reserve Active Power Margin notifications, which are a way for Britain's electricity plants to reduce output to maintain grid stabilty. (Reporting and editing by Bernadettebaum)
