Jones Bros Civil Engineering UK has been appointed as principal contractor for the 20-turbine Windy Standard III wind farm in Dumfries & Galloway.
The Fred Olsen Renewables-led development, first consented in 2021, will be capable of generating 87.6 megawatts of renewable energy. It will have the capacity to power more than 130,000 homes a year.
Scheduled activity for Jones Bros includes ground investigations, reinforced concrete foundations, excavating, and backfilling for cabling, as well as creating more than 10km of new access tracks and associated crane hardstands to allow for turbine delivery and erection.
Jones Bros project manager Jonathan Maitland said: “Our highly skilled team is pleased to have been given the green light on Windy Standard III, which further strengthens our wind farm portfolio in Scotland. We look forward to working closely with Fred. Olsen Renewables to add to the first two phases of the complex and boost the push towards clean power.”

The family-owned contractor’s Scotland-based team is to be expanded by recruitment in the local region, with around 45 staff, including apprentices, set to be on site.
Jones Bros will also use its on-site batching plant to cut down vehicle movement and help streamline programme delivery.
First power generation from the wind farm near New Cumnock in southwest Scotland is expected in winter 2026.
Sofie Olsen Jebsen, chief executive officer at Fred Olsen Renewables, said: “We are delighted to be starting construction on Windy Standard III. This is a strategic project for Fred Olsen Renewables and demonstrates our continued commitment to the UK market.”
