Problems and difficulties in managing the electric grid have forced the UK government to spend £1 billion (€1.21 billion) so far this year to cut wind farm output.
While the UK has an increasing amount of renewable energy production, the country is unable to process it properly.
According to Bloomberg, “the grid can’t cope, forcing the operator to pay wind farms to turn off, a cost ultimately borne by consumers.”
“Britain has boosted its offshore fleet by 50 per cent in the past five years and is set to double it in the next five, data from BloombergNEF show.”
“But the grid hasn’t expanded at the same pace. As a result, the operator is increasingly paying wind farms, particularly those in Scotland, not to run.”
As a result the UK spent over €1 billion on so-called “congestion costs”.
During big storms, such as last month’s Storm Ben, the UK shut off some of its newest and biggest wind parks, including Scotland’s £3 billion Seagreen project.
Plans to expand the amount of wind farms off the Scottish coast could make the bottleneck even worse, Bloomberg noted, unless the grid is expanded.

In the UK’s electricity market, generators sell output in advance, but this doesn’t account for real-time supply and demand challenges. To prevent blackouts, grid operators must pay some plants to stop generating electricity while simultaneously triggering other plants to start, ensuring a stable power supply.
“Often, this means shutting off a far-flung wind farm and starting up a gas-fed plant that’s closer to a city.”
“The outdated rules of our energy system mean vast amounts of cheap green power go to waste,” said Clem Cowton, director of external affairs at supplier Octopus Energy Group.
“It’s absurd that Britain pays Scottish wind farms to turn off when it’s windy, while simultaneously paying gas-power stations in the south to turn on.”
Annual grid infrastructure investments of approximately £40 billion will be necessary to achieve the government’s 2030 net-zero targets, according to the new state-owned National Energy System Operator.
The UK’s grid transformation will be lengthy and costly. As the government builds European interconnectors to secure electricity during low-wind periods, British consumers face rising energy prices.
With tight European supply, these imported watts will likely be expensive, compounding existing grid management and “congestion” expenses.
Costs for an energy island in the North Sea, connecting offshore wind farms, have turned out to be more than three times as high as expected. https://t.co/jdc3ohnLuY
