Owners of the UK’s last remaining coal power stations are in line to be paid record sums to keep the lights on as energy prices reach fresh highs, and could be pushed even higher by lower wind power.
Coal plants have been called on to supply power steadily in recent months, through one of the least windy summers on record since 1961 and sharply rising prices in the wholesale energy market.
The UK’s electricity system operator (ESO) spent more than £86m last week alone to keep the lights on, which involved making payments of up to £4,000 a megawatt-hour for fossil fuel power stations to generate electricity at short notice, including the West Burton plant in Nottinghamshire and a coal unit at the Drax site in North Yorkshire.
Britain has largely been weaned off coal power in recent years, but the remaining plants are available on standby to accept eye-watering offers from National Grid ESO at times of need, such as during cold spikes or low wind conditions . The Ratcliffe-on-Soar coal plant near Nottingham is also in line to benefit from record power prices this week.
The price of electricity on the UK’s main power auction rose above £400 a MWh for the first time on Monday, while the price of gas surged to a record of 150 pence a therm.
The increases follow market highs last week. Experts predict UK wholesale energy prices will climb higher in the days ahead owing to forecasts of low-wind speeds, which will limit the country’s renewable energy generation.
The price for electricity during Tuesday evening’s peak power demand hours has reached a new record of £1,750 a MWh, more than 2,900% higher than the average price over the last decade, according to Bloomberg data.
Prices have soared in recent months owing to a global gas market surge, which followed a cold winter in the northern hemisphere that left gas storage facilities depleted. The record gas price has made electricity more expensive in the UK, where almost half of all electricity is generated in gas power plants.
In addition, the UK has faced a “perfect storm” of power plant outages and low wind speeds that has forced energy prices higher despite demand “not being very high at the moment”, according to Rajiv Gogna, a partner at LCP Energy Analytics.
Phil Hewitt, a director at the energy consultancy EnAppSys, added that Wednesday and Thursday looked even more volatile than the start of the week, “so we suspect that this is not the end of the high prices”.
The record market prices are expected to lead to hikes in household energy bills through until 2022, plunging more than people in the UK into fuel poverty for the first time and causing many small energy suppliers to go bust.
Clare Moriarty, the chief executive of Citizens Advice, said it was deeply concerning that energy prices were continuing to rise, “meaning we’re likely to see yet another hike in bills next year”. https://www.theguardian.com/business/2021/sep/13/britain-last-coal-power-stations-to-be-paid-huge-sums-to-keep-lights-on-record-energy-prices
