TNU initiated developing the Snapper Point Power Station at Harbor, SA and the works involved relocation of five generators. The new power station is to operate as a peaking plant primarily operating on natural gas but can switch to liquid fuel.
APD Engineering was engaged to provide Detailed Design Services for the works below:
The new Snapper Point 275/66kV substation comprising of two 140MVA Power Transformers, three 275kV Bays, two 66kV Bays.
The existing Pelican Point comprised of three 275kV Bays, Synchronising and protection coordination with Pelican Point power station.
The connection between the new Snapper Point and the existing Pelican Point substations comprises of approximately 400m of 275kV Transmission Line.
