ABB at Sloy.jpg ABB has been awarded a fast-track turnkey project by Scottish and Southern Energy Power Distribution (SSEPD) to construct the replacement for the Sloy 132 kV substation that serves a large area of Western Scotland, as well as providing the grid connection for SSE’s most powerful hydro-electric power plant. The use of ABB’s state-of-the-art high-voltage gas insulated switchgear (GIS) technology will enable the new substation to be constructed within a compact, low profile granite-clad building designed to blend in with its surroundings in the Loch Lomond & Trossachs National Park. The existing 14-bay Sloy substation, based on outdoor air insulated switchgear (AIS) technology (pictured), has reached the end of its 40-year design life. SSEPD is now replacing it to ensure the reliability and continuity of its power network, especially with plans to upgrade the Sloy hydro-electric plant to a pumped storage facility capable of supplying 100 GWh a year. ABB will build the new indoor GIS substation alongside the existing AIS substation as well as installing 7 km of 132 kV XLPE cable to connect the switchgear with the overhead line circuits. When the project is completed and all the circuits have been transferred over, the old substation will be demolished and the site landscaped and restored to its natural condition.
