Developments: 2. In July 2026, ScottishPower announced a major repowering project for the Whitelee on‑shore wind farm, the United Kingdom’s largest on‑shore installation. The plan involves replacing the existing 214 turbines with roughly 120‑124 new, taller machines that will raise the farm’s capacity from about 533‑539 MW to over 1 GW, enough to power between 650 000 and 1.5 million homes. The investment is valued at £1.5 billion (≈ €1.8 billion) and is part of a broader £24‑28 billion UK programme by ScottishPower’s parent Iberdrola to expand renewable generation and modernise the grid through 2028. The project is slated for phased construction during the 2030s, with commissioning targeted around 2035. It is expected to create hundreds of construction jobs, generate £380‑500 million of gross value added for the Scottish economy, and deliver several million pounds per year in community benefit payments, while bolstering UK energy security and helping to lower consumer electricity costs. ## Timeline ### 2026-07-31: Iberdrola to double Whitelee wind farm capacity with €1.8bn investment Iberdrola, through ScottishPower, will invest €1.8 bn to repower the Whitelee wind farm in the UK, raising capacity from 539 MW to 1 GW and supplying clean power for 1.5 million people while boosting the Scots’ 4 sources. https://clstr.news/cluster/iberdrola-to-double-whitelee-wind-farm-capacity-with-18bn-investment ### 2026-07-22: ScottishPower to double Whitelee windfarm output using taller turbines ScottishPower will repower Whitelee windfarm, swapping 214 turbines for 124 taller ones to lift capacity from 533 MW to over 1 GW, creating jobs and annual £5 m community benefits. 5 sources. https://clstr.news/cluster/scottishpower-to-double-whitelee-windfarm-output-using-taller-turbines --- Cite as: Whitelee wind farm repowering expansion.
