London — Britain’s National Energy System Operator (NESO) has cancelled an electricity margin notice it issued earlier on Wednesday calling on generators for more power to be available on the system.
“Electricity margin notice issued for the period from 1600 to 1900 hrs on Wednesday 08/01/2025 has been cancelled,” the NESO posted on the Elexon website.
Late on Tuesday, with much of Britain entering a cold weather snap, it issued an electricity margin notice for Wednesday evening. Peak electricity demand is typically in the evenings in Britain in winter.
The NESO is responsible for maintaining Britain’s power supply and has a range of measures available to ensure there is enough electricity to meet demand.
It said earlier today there could be a system margin shortfall of 1,120 megawatts compared with the amount it would like to be available.
It also issued a capacity market notice but cancelled it shortly after.
Under the capacity market scheme, generators are paid to make sure power generation is available at times when demand is high.
“Both of these notices are part of NESO’s operational toolkit and are routine tools used most winters,” a NESO spokesperson said in an emailed statement.
