Case Study - Large Wind


Levenseat, West Lothian

Tormywheel Wind Farm comprises a 30+MW, 15 turbine development south of Whitburn within West Lothian. Green Cat Renewables (GCR) assisted the developer Muirhall Energy to finalise the design layout, compile tender scope and award a Design and Build contract in March 2016 for completion by March 2017.

GCR acted as the Client’s Engineer, liaising with stakeholders preparing tenders, and managing the three separate contracts for Balance of Plant, Turbine Supply and Grid Connection. The role of CDM Principal Designer was also included to
ensure compliance with CDM 2015 Regulations.

The site is located on elevated peaty moorland adjacent to an operational landfill site. GCR Geotechnical carried out the ground investigation study which included mining investigation and contaminated land reviews, alongside the standard site investigation to inform foundation design.

To achieve the March 2017 Ofgem ROC deadline it was necessary for GCR to actively co-ordinate actions of all the parties involved.

Muirhall Energy has a portfolio of several wind projects three of which have been successfully delivered by GCR.
