£16 bn of Scottish wind blown away

Green power is going to waste because it cannot be sent south of border

THE UK is set to waste more than £16billion this decade after regulatory and planning failures have left Scotland producing more wind power than can be transmitted down South.

The cost, calculated by thinktank Carbon Tracker, is expected to find its way into higher electricity bills for cash-strapped households and businesses.

The problem arises because, although the UK is a wind superpower, there are not enough cables to take renewable electricity from Scotland, where most of it is produced, to England, where most of it is needed.

When bottlenecks arise, wind farms are paid to switch off their turbines, and gas stations in England are paid extra to supply the necessary electricity.

The system, known as curtailment, cost more than £700million in 2023, with a further £140million spent in January and February of this year alone.

But costs are expected to shoot up, as offshore wind farms continue to grow, while cable construction remains mired in long drawn-out approval processes.

‘Wind curtailment could grow five-fold by 2030, costing £3.5 billion and wasting electricity equivalent to the annual consumption of more than 5million households,’ says Lorenzo Sani of Carbon Tracker.

The price tag stems primarily from payments to gas providers, which have already made almost £1.5billion by making sure Britain can keep the lights on when transmission cables cannot cope with Scottish wind.

Planning failures do not just hit UK purse-strings however. They also mean that enormous amounts of green power – up to 20 per cent in some months – is replaced by fossil fuels. Moves to address the problem are under way.

Last week, regulator Ofgem said it would fast-track a socalled ‘electricity superhighway’ between Scotland and England with an additional £2billion in funds. The proposed subsea cables could transport wind-generated electricity between East Lothian and County Durham.

And earlier this year, ESO, the electricity system operator, unveiled Beyond 2030, a £58billion plan to ensure power can be transported more effectively around the UK in future. Beyond 2030 estimates that electricity demand will be 65 per cent higher in 2035 than it is today, fuelled by a growing reliance on electric cars and heating.
