When complete, the wind farm will host 31 wind turbines that will produce up to 112 megawatts of clean, renewable energy available to Tasmanians; diversifying the state’s energy generation mix. This is enough electricity to power around 46,000 homes.
The wind farm will be connected to the Tasmanian grid via a new 12.5km transmission line that will join up to a connection point at the existing Reece Dam.
Zinfra were engaged by TasNetworks to design and construct the 11km Single Circuit 220kV Steel Pole Transmission Line, a 220kV Switching Station, and a 1.5km Dual Circuit 220kV Lattice Steel Tower Transmission Line across the Reece Dam wall connecting into the Hydro Tasmania Reece Power Station. Scope of works include:
Clearing, stock piling and site development: Clearing of site vegetation;
Construction of temporary and permanent access tracks;
Benching and levelling of proposed construction area;
Stockpiling of construction aggregate.
Switching Station design and construction:
6 x 220kV disconnectors;
3 x 220kV circuit breakers;
Associated post insulators & solid bus;
12 x Capacitive Voltage Transformers (CVTs);
New conduit systems to new equipment;
New Pre-fabricated control building;
New fence arrangement;
New access track & associate internal pathways;
Associated secondary cabling and equipment;
Associated primary conductor and compression fittings.
Transmission line design and construction:
11km single and 1.5km dual circuit 220kV transmission line to the new Dual OPGW Circuit Pieman Switching Station;
Two new circuits with hard tee at the Farrell – Reece No.1 and No.2 translines adjacent to the Reece Power Station;
Pole and tower foundation designs allowing for foundation type selection based on confirmed ground conditions;
Pole and tower erection;
All associated stringing activities.
