Extra Energy Gone With the Wind
Wind power is, without a doubt, a promising solution for the UK's need for sustainable and renewable energy sources. However, a recent report by Carbon Tracker revealed that wasted wind power will add a significant burden to the average UK household's electricity bills. In 2023 alone, the estimated cost was £40 per household, with projections indicating a potential increase to £150 by 2026.
Cash to Curtail
When weather conditions are favourable, the National Grid generally struggles to accommodate the surplus power generated by wind farms. In response, these sites are paid to shut down.
The cost of this compensation is passed on to consumers, contributing to ever-rising electricity bills. The report from Carbon Tracker reveals that wind ‘curtailment’ payments tally to a staggering £590 million in the space of 12 months.
Bottleneck at the Border
One of the primary obstacles to the efficient use of wind power is the bottleneck in transmission between Scotland, the location of many wind farms, and England, which consumes the majority of energy.
Carbon Tracker’s report emphasised that the key issue lies in the insufficient grid infrastructure, particularly the lack of transmission cables. Unless the UK makes sweeping changes, the additional costs could reach £180 per household per year by 2030.
Infrastructure Investment Needed
Analyst Lorenzo Sani reiterated the simplicity of the solution. He said: "The problem is, there are not enough cables. The logical solution would be to build more grid infrastructure. It's not even that expensive.”
Barnaby Wharton of the industry group RenewableUK said: "This reflects a chronic lack of investment in the grid. We need to move from an antiquated grid which wastes power to one that's fit for purpose in the 21st Century as fast as possible."
The Government’s Guarantees
While the UK Government has acknowledged the need for reform, there are challenges ahead. Energy regulator Ofgem introduced new rules in November 2023 that seek to accelerate the implementation of new grid connections.
The Government has also pledged to halve the time it takes to build energy networks to accommodate extra wind power. However, Carbon Tracker remains sceptical about the effectiveness of these measures, citing a historical delay in approving new transmission cables.
The UK’s transition to renewable energy sources, such as wind power, is a crucial step in combatting climate change and shoring up energy security. However, the challenges associated with wasted wind power and the resulting impact on energy bills call for urgent action.
Addressing the transmission bottleneck at the Scottish-English border and investing in improved grid infrastructure is essential to harnessing the full potential of the wind.
