UK power prices rise to four-year high

Bloomberg

UK power prices rose to a four-year high after the UK grid operator warned that its safety buffer of supplies was almost eroded for Sunday. National Grid Plc said it’s “monitoring the situation closely” in a warning published on Twitter.
The network operator stopped short of issuing an official alert called an Electricity Margin Notice, which is published when the normal safety margin for operating the system shrinks below the level permitted by the government.
It’s unusual for there to be problems meeting demand on a weekend when consumption is typically lower as offices and industry shut. That shows how close to the edge Britain’s power system is this winter.
National Grid has been expecting more supply warnings this year, Chief Executive Officer John Pettigrew said in an
interview with Bloomberg last month. The margin between power supply and demand is the narrowest the UK has seen in about four years, he said.
