Wind power plants pay to refrain from producing up to half of the electricity they can generate, according to a study that warned MPs that “inappropriate” decisions about wind power “impose excessive costs on consumers.” It has been.

Analysis found that in 2020, three large wind farms in Scotland were paid a total of £ 24.5 million, failing to produce about half of their potential output.

The researcher said “Restricted payments”Will eventually be added to consumer invoices, but fueled by onshore wind farms concentrated in Scotland, the power grid was often out of service on windy days.

The Renewable Energy Foundation, a charity that publishes energy data, said the problem would continue “until there was a sufficient interconnection between Scotland and the UK’s center of demand.”Analysis is moving forward Expected surge in electricity bills..

Craig Mackinlay, who heads the Net Zero scrutiny group of Conservative lawmakers, said payment of constraints is an example of unnecessary costs charged to consumers.

Government spokesmen argued that payments were “not a viable source of income for onshore wind developers,” but a new analysis by REF shows that some individual wind plants have potential output to avoid. I found that I agreed not to produce up to half of the quantity Overwhelm the grid..

Excessive costs are “forced by consumers”

In one case, a £ 7.7 million “constrained payment” given to the operator of the 23-turbine scheme in Scotland in 2020 intentionally prevented wind farms from producing 51% of their potential output. In another example, SSE, the operator of the Strathy North wind farm with 33 turbines in the highlands, was paid £ 5.9 million to avoid producing 48% of its capacity.

Due to particularly low wind speeds last year, EDF Renewables-owned Moray’s 59-turbine Dorenell wind farm will generate £ 1.5 million to avoid a total of 179 gigawatt hours of electricity, which is 35% of its potential output. Was paid.

Dr. Lee Moroney, Principal Analyst at REF, said: .. “

Turbines appear to be “built in the wrong places, costing consumers too much and damaging our precious natural heritage in the process,” McKinley said.

More Renewable Energy “Protects Customers”

A government spokesman said, “Because gas is expensive and wind is cheap, we need more renewable energy to protect consumers. Constraint payments are still for the National Grid to maintain UK lighting. It is the most efficient option and is only used in case of oversupply. “”

A spokesman for EDF Renewables said that “to manage the system and keep it on”, we need to meet the constraints of the National Grid.

Alistair Phillips-Davies, Chief Executive Officer of SSE, said: “”

Scottish Renewables, an industry group, said paying constraints added just £ 1 a year to the average household’s electricity bill.

On Friday, in strong winds, about 40% of the day’s electricity supply was generated by turbines. This is much higher than average. Brought by Storm Eunice..
