Scottish Power is set to invest £1.5 billion to repower the Whitelee Windfarm in Scotland, replacing 215 existing turbines with 124 larger models. The project, expected to run from 2030 to 2035, will nearly double the site’s capacity to approximately 1 gigawatt, enough to power roughly 650,000 homes.
Repowering the UK’s Largest Onshore Wind Farm
Originally commissioned in 2008 and expanded twice since, the site is currently the largest onshore wind farm in the UK.
The plan involves a transition from the current 215 turbines to 124 taller, more efficient models. According to reports, the new turbines could reach heights well above 240 metres at the blade tip, compared to the current maximum of 140 metres. This increase in scale is intended to boost the site’s output from 533MW to over 1GW.
Keith Anderson on Landscape and Environmental Impact
Scottish Power CEO Keith Anderson, speaking to BBC Radio Scotland Breakfast, addressed these concerns by framing the site’s history and current status.
“They will be bigger and taller, but you need to put that in context of the landscape. It’s a huge open area which was covered with commercial forestry, a lot of which we’ve taken away. We’ve turned the environment back to actually more of its natural state.”
Keith Anderson, Scottish Power CEO
Anderson emphasized that the repowering process is essential for the future of the site. He argued that allowing the current capacity to dwindle as turbines expire would be a step backward for the country’s clean energy goals. If we increase the size of the site and the output of the site, then we generate more renewable power for the country, which is a brilliant thing,
Anderson said.
Operational Timeline and Energy Debt Context
The transition is scheduled to occur in three phases to maintain public access to the visitor center, which has been open since 2008. Construction is slated to begin around 2030, with full completion expected by 2035. During this period, the company plans to operate the site in sections, ensuring that energy generation continues while new infrastructure is installed.
Beyond the wind farm project, Anderson has also commented on the broader economic challenges facing the energy sector. Following parent company Iberdrola’s announcement of a 22% rise in first-half net profits to €4.34 billion, Anderson addressed the issue of household energy debt in the UK, which industry group Energy UK estimates could reach £7 billion by the end of the year.
Anderson expressed support for Prime Minister Andy Burnham’s move to remove VAT from domestic electricity bills, but suggested that systemic intervention is required to clear the existing debt burden. We need to take away some of that old debt burden because people clearly just can’t afford to pay it,
he noted, proposing a securitized fund to be repaid over 10 to 15 years.
Political Discourse Surrounding Wind Energy
Former Downing Street chief of staff Morgan McSweeney shared with the BBC’s Political Thinking with Nick Robinson
podcast an account of a phone call between Prime Minister Sir Keir Starmer and US President Donald Trump.

According to McSweeney, the conversation touched on the presence of wind turbines in the UK, with the President suggesting that windmills
were killing birds and causing foxes to become too fat to recognise
after eating them.
