The Republic of the Fiji Islands, the implementing agency being the Fiji Electricity Authority (FEA) has applied for financing from the World Bank toward the cost of the Nadarivatu Hydropower Project, and intends to apply part of the proceeds for consultant services. The services include among other things design, review, performing the function of “Engineer” in the civil works contract, “Project Manager” under supply and installation contracts.
Project Description
The Nadarivatu hydropower scheme proposes to construct and operate a 40 megawatt (MW) hydropower scheme in the Nadarivatu district with a mean annual output of 100 GWh. The scheme comprises of a 35 m high weir at Korolevu, approximately 3.5 km of Tunnel & Penstock, Powerhouse for 2×20 MW turbines at a head of 300 m with all associated Mechanical & Electrical Plant, and a 132 kV transmission system with substation to integrate into the existing 132 kV grid.
The scheme involves taking water from the 35m Korolevu weir, located in the Sigatoka River catchment approximately 50 m downstream of the Qaliwana and Nukunuku Creek confluence, through a 2 km tunnel from weir to penstock and km penstock to a power station on the banks of the Ba River. The weir will have the capacity to store up to 1,000,000 cubic metres (m3) of water which, at the maximum scheme discharge of 15 m3/s, is 8 hours storage.
The power house will be located on the bank of the Ba River and will house 2 Pelton wheel turbines with individual generators and balance of plant with PLC controls and associated switchgear and protection systems.
A loading bay and office annex will be provided within the main building, adjacent to the loading dock. This will house the controls, 415 volt (V) electrical panels, operator stations, office accommodation, communication equipment and standby generator. In addition, sleeping accommodation and cooking facilities will be provided for operating personnel and maintenance staff.
New road construction involves access to the Korolevu intake which will be obtained off the Lewa Road. It will pass the original Lewa intake and pass along the right bank of the Nukunuku Creek. Access to the Ba Power house and the downstream tunnel portal will be obtained from the Lewa Road above the Buya Buya Village. The road will also provide access to the Buya Buya Village. The access road to the Buya Buya Village will also be extended to provide road access to the high voltage substation near to the Buya Buya Village.
Mechanical and Electrical Plant configuration includes two Pelton turbine generators at the power station, Power house equipment and cranes. controls and communications, two 132KV lines from the Power house to the substation adjacent to the Buya Buya Village, a 132kV substation adjacent to the village, a 132 kV 5.4 km dual circuit transmission line from the substation to the existing Vuda / Wailoa transmission line and upgrade of communication and electrical protection systems between Vuda and Wailoa power station.
