Iberdrola to Invest £1.5bn in Whitelee Windfarm Repowering Project
Iberdrola plans a £1.5bn investment to repower Scotland's Whitelee Windfarm, replacing 215 turbines with 124 larger units. This project aims to double output to 1GW over a decade, signaling a trend towards larger onshore wind projects in the UK.

Iberdrola will invest £1.5bn to replace 215 existing turbines at Whitelee Windfarm with 124 larger models, projected to increase electricity output from 539MW to 1GW over ten years. This initiative follows similar actions in 2023 when Scottish Power upgraded turbines on Scotland's first commercial wind farm.
The repowering trend is expected to grow, driven by the maturing onshore sector, particularly in Scotland. There are ongoing discussions regarding financing models for such projects as traditional mechanisms may phase out.
Alongside this, battery energy storage systems are expanding, addressing grid constraints. The completion of necessary grid upgrades is anticipated around 2035.
