Government Slashes Forecasts for Wind Farm Electricity Generation

Strategic Insights -

Ed Miliband's net zero plans face a major blow after the Government revised down the predicted efficiency of wind turbines, sparking concerns that the Energy Secretary will struggle to meet his clean power targets. The revised estimates, published before an auction of green energy subsidies, suggest that wind farms will generate significantly less electricity than previously thought. Industry experts warn that this could lead to higher subsidies being paid to wind farms, making it harder for Labour to achieve its goal of switching the electricity system to 95% clean power sources by 2030.

Key Takeaways:

  • The Government has revised down the predicted efficiency of wind turbines by more than a quarter, citing "updated modelling" as the reason.
  • The estimated load factor for offshore wind turbines was revised from 61% to 43.6%, while onshore turbines' load factor was revised from 48.7% to 33.4%.
  • The downgraded estimates suggest that wind farms will generate less electricity than previously thought, sparking concerns that Ed Miliband's net zero plans are facing significant challenges.
  • Industry experts warn that higher subsidies will be needed to secure the same amount of energy from wind farms, making it harder to hit Labour's clean power targets.
  • Deputy Leader and Energy Secretary Ed Miliband is committed to switching the electricity system to 95% clean power sources by 2030, but the downgraded estimates raise doubts about his ability to achieve this goal.
  • RenewableUK estimates that Labour needs to secure at least another 12 gigawatts of capacity to meet its targets, but has only budgeted for five gigawatts in the latest auction.

Statistics:

  • The revised load factor for offshore wind turbines is 43.6%, down from 61%.
  • The revised load factor for onshore wind turbines is 33.4%, down from 48.7%.
  • RenewableUK estimates that the current actual load factor for offshore turbines is around 38%.
  • The Government has revised down the predicted efficiency of wind turbines by more than a quarter.
  • The UK wind farm generation dropped by 5% due to "lower wind resource", according to Spanish utilities giant Iberdrola.
