PROJECT DESCRIPTION

Kirby was responsible for the design and build on Glenconway Windfarm development which consisted of a new Windfarm connecting over 50MW of renewable energy to the grid using the capacity on an existing SSE IPP substation located 20km away at Slieve Kirk.

Kirby was responsible for the design, supply and install of the EBOP plant at Glenconway Windfarm including electrical installation of the 33kV substation and outdoor AIS compound, 33kV collector circuits and supply and installation of 20 no. 33kV – 690V unit substations.

This complex project required Kirby to interface and modify the existing Slieve Kirk Windfarm substation, while minimising the required outages. Modifications were required to the existing 110/20kV power transformer, its control and protection systems and common substation systems. This allowed the client to fully utilise the capacity on their existing 110kV grid connection.

The requirement for a 33kV filter at Slieve Kirk was only identified upon completion of the system studies. Kirby was required to complete further installation works and modifications to the control and protection systems at Slieve Kirk to incorporate the filter.
