ERG has increased capacity at its SandyKnowe and CreagRiabhach wind farms, currently under construction in Scotland, to 90MW and 92MW respectively, by using higher rated turbines.
The Italian developer said the increase at CreagRiabhach, on the Altnaharra Estate in the Highlands,had also been enabled by an increased grid connection capacity, up from 79MW to 92MW.
Meanwhile the company received the green light earlier this year from the Scottish government to vary its consent for the Sandy Knowe scheme, south west of Kirkconnel and Kelloholm in Dumfries and Galloway, removing a previous 48MW capacity limit.
The changes will be implemented without altering the layout of the original projects. ERG declined to provide details of turbine choice.
Total investment for the constructionof the two wind farms amounts to about €214m.
The developer said an initial 50MW first phase at Sandy Knowe will be brought online by the end of 2021 with the remainder during the first six months of 2023.
The project will feature 24 turbines standing at 125 metres.
CreagRiabhachis expected to come into operation by the end of 2022 and will feature 22 turbines, also 125 metres tall.
