Iberdrola plans to double the capacity of Whitelee, the UK's largest onshore wind farm

Iberdrola, through its UK subsidiary ScottishPower, has announced a plan to repower Whitelee, the country's largest onshore wind farm, in the coming years.

The initiative, which would involve investments of €1.8 billion, involves replacing the current wind turbines with more modern and powerful turbines in the coming years, increasing the complex's capacity from the current 539 megawatts (MW) to 1,000 MW. Once completed, Whitelee would produce enough clean energy to supply more than one and a half million people.

The project's positive impact also extends to boosting economic activity and employment, generating €380 million in gross value added for the Scottish economy over the next decade and hundreds of jobs.

Whitelee is one of the leading benchmarks for electrification with renewables in Europe. Since it came online in 2008, the wind farm has supplied clean electricity to millions of homes and has become a strategic asset for the British electricity system. Repowering will make it possible to leverage existing infrastructure to extend its useful life and maximise its contribution to the electrification of the economy and decarbonisation.

This project is part of Iberdrola's commitment to the UK, one of the Group's main investment destinations. Through ScottishPower, the company plans to invest £28 billion by 2028 to boost electrification, mainly through more electricity grids and renewable energy, contributing to energy independence, industrial competitiveness and job creation.
