Stronelairg Wind Farm Case Study - Promat, Duratseel

As a leading provider of renewable energy across the UK, SSE Energy Services aims to drive the transition to a net zero carbon world through the development, construction and operation of state-of-the-art renewable energy assets. To support this mission, in 2017 SSE built a wind farm in Stronelairg - a remote area of Scotland near Loch Ness. At an elevation of around 600 meters above sea level, it is one of SSE’s windiest sites. The site includes 66 wind turbines and has the capacity to generate 228 MW of energy.

As part of the project, SSE needed to create three transformer enclosure bays on the site, each of which had to meet a demanding four-hour fire-rated standard. This required the installation of walls and ceilings - as well as internal access doors for maintenance personal - that would all meet this high-level of fire resistance. It was also necessary that various penetrations, including wall bushings, were able to safely pass through the barriers in the enclosure bays.

An additional challenge was that the project would have to be completed in an isolated setting where the work would be constantly exposed to cold, wet weather conditions. 

Having worked with Promat and its products for more than a decade, the project’s subcontractor, Invicta, knew its fire protection solutions would be a perfect fit for the wind farm’s unique requirements.
