The National Grid has put two coal-fired power stations on standby to meet extra demand
(Picture: John Giles/PA)Britain’s electricity grid operator has asked two of its coal-fired power stations to start warming up as freezing weather conditions heap pressure on the UK’s power network.
National Grid said it had asked the winter “contingency” plants to prepare for operation to “give the public confidence in Monday’s energy supply”.
It said the move means the coal-fired stations can be used as “tools for additional contingency” as needed to allow the network to run as usual and stressed that people “should continue to use energy as normal”.
The UK faces its biggest test yet with the current cold snap – which has seen the country suffer freezing temperatures and snow in many areas – ramping up demand for power at a time when supplies are tight.
UK next-day electricity prices surged yesterday to help attract power imports through interconnectors from Europe and record prices are expected during the peak demand hours between 5pm and 7pm on Monday.
The instruction for the coal-fired plants marks the first since they were put on standby and comes as the grid said it will also run another test of its demand flexibility service – which pays customers to use less electricity during certain hours.
On Monday, customers of some energy suppliers will be asked to reduce their consumption between 5pm and 7pm this evening.
National Grid says that the service is just a test and had already been planned for today, however, the timing will likely still be useful on a day when energy prices have shot up.
Octopus Energy has promised that its customers can save more electricity than other suppliers, with Drax and Eon also saying they can provide significant savings for the grid.
The grid expects that the coal-fired stations will be ready for use if called upon between 5pm and 9pm, when demand is set to peak.
The stations are operated by Drax in North Yorkshire and are two of five put on standby under so-called winter contingency contracts, with others run by EDF and Uniper.
The two units are each said to be capable of generating around 570 megawatts – adding more than 1.1 gigawatts to the grid if used.
