Scott Base Redevelopment Project - RIWE Electrical Detailed Design RFP

Antarctica New Zealand (AntNZ) is currently upgrading the Ross Island Wind Energy (RIWE) system, the grid that connects Scott Base, the Crater Hill Wind Farm and the United States’ McMurdo Station.

Antarctica New Zealand is seeking tenders for an electrical design consultant (Designer) to help facilitate this upgrade by completing detailed electrical design and supporting AntNZ through the procurement and construction phases.

The upgraded RIWE system assets includes:
• 3 x Emergya Wind Technologies (EWT) DW54x‐1MW wind turbines;
• A Battery Energy Storage System (BESS);
• Power Plants A and B at McMurdo Station;
• Upgrading the 4.16 kV High Voltage (HV) network between Scott Base, the Crater Hill Wind Farm,
and McMurdo Station with higher capacity cabling (including fibre optic cables);
• Installing a new Microgrid Control System (MCS), Supervisory Control and Data Acquisition (SCADA) and historian system to control and monitor the status of the RIWE network;
• New Scott Base (New Zealand’s Antarctica base).

The existing assets (3 x Enercon E‐33 wind turbines and PowerStore) will also be removed as part of the RIWE upgrade project.
