Case Study - Medium Wind

Deuchries Wind Farm

Aberchirder, Huntly

In 2016, Green Cat Renewable Developments Limited (GCRD) purchased the Deuchries Wind Farm project after the previous owner decided the project was no longer viable due to reducing subsidies, complex grid restrictions and challenging site conditions.

With Green Cat Renewables’ in-house expertise and good working relationships with the local DNO, a more economical grid solution was obtained allowing the project to proceed through the development stage to construction. The on-site electrical works and the ICP contestable works were carried out by Green Cat Renewables’ sister company, Prelec Limited. Their scope of works included just under 3km of underground cabling and an on-site 33kV substation.

The challenging site conditions with extensive cut and fill was undertaken by Green Cat Contracting (GCC), who were able to carry the works out efficiently and economically. One of the first tasks for GCC was to establish two on-site borrow pits to provide the large quantities of fill material required to form the access tracks and crane hardstandings.

Green Cat Renewables were able to provide detailed site design to GCC using data obtained from extensive ground investigation work carried out by the in house Geotechnical Team.

This project is a great example of the various companies, under the Green Cat umbrella, working together to deliver projects cost effectively while dealing with challenges that other developers may be unable to overcome. The turbines were delivered as planned in August 2017 and were commissioned in January 2018.
