Britain Paying 17 Times More to Import Energy From Europe During Heatwave
The UK paid nearly £1,400 per megawatt hour – about 17 times the normal prices – on Wednesday evening to obtain emergency supplies from the Continent in a move set to add £11 million to bills.
National Energy Systems Operator (Neso), which balances daily electricity supply and demand, paid the sky-high prices after a shortfall in energy generated from domestic solar and gas-fired power stations left the UK scrambling for supplies.
The situation meant Neso was forced to obtain a special dispensation from its EU counterparts to buy the power. The EU has limited sales to the UK because of the effect on the Continent’s own electricity supplies.
It came after a surge in air conditioning use to cool shops and offices, as well as malfunctioning solar panels, which led to a drop in domestic power generation.
Britain has been hit with record June temperatures of 36.4°C, with the Met Office issuing a red warning for extreme heat for three consecutive days lasting until Friday.
NoĆ©mie Baud, from Montel, an energy consultancy, said Neso appeared to have underestimated the demand increase caused by the heatwave by up to three gigawatts – equivalent to the output of three nuclear power stations.
“Neso appears to have underestimated the amount of demand that we have in the UK,” she says. “The UK now has a lot of shops, industry, offices and businesses, and they all have aircon, so the aircon effect on demand definitely does matter.
“It was underestimated by Neso because we could see that the demand was actually even higher than it forecasted.”
Industry data show that at the peak, between 8pm and 9pm on Wednesday night, Neso was paying sky-high prices of £1,379 per megawatt hour – a massive premium on the usual wholesale power price of around £80 per megawatt hour.
Neso bought up to 2.3 gigawatts of extra capacity, mainly from the Netherlands, to balance the electricity supply system.
