Wind farm

Drumduff wind farm

Project location

The site of this three-turbine project is an old, disused open cast coal mine to the north of Blackridge in West Lothian, Scotland and close to the main train line between Glasgow and Edinburgh.

As part of our construction, remnants of the open mine will be made safe and small areas will be landscaped to provide appropriate access, hard standings and infrastructure for the wind farm in line with the planning consent.  The majority of land will be allowed to return to its native ecology over time.  The site's 47 hectares also incorporates an area of natural woodland which will be managed alongside the wind farm development.

The site is adjacent to an existing wind farm, testament to the good wind resource in the area. 

Project summary image

Project summary

The project is being built as a joint venture between Thrive Renewables and GreenPower - an organisation we have built a strong working relationship with over many years and who are based nearby to help oversee work on site.  The name of the joint venture company is Green Breeze Energy.  The Drumduff wind project was initiated by a family consortium who sold the project to us in summer 2016. 

Once built, the 6MW project is forecast to generate enough renewable electricity to meet the annual demand of 5,458 UK homes.  Construction is due to be completed with the first export to the grid in early summer 2017.

The control and substation building progress. The site team are tying the reinforcement steel for the Scottish Power HV room.

The roads onsite were constructed using a soil stabilisation construction methodology. These tracks will be capped with stone and shaped off in the coming weeks.
