Nadarivatu Dam

The Nadarivatu Dam, also known as the Korolevu Dam, is a concrete gravity dam on the upper reaches of the Sigatoka River in Nadarivatu District of Nadroga-Navosa Province, Fiji. The primary purpose of the dam is to generate hydroelectric power in a 41.7 MW run-of-the-river scheme. The Nadarivatu Hydropower Scheme was first identified in 1977 during a hydropower study. Detailed plans for the project were developed in 2002 and major construction began in 2009. The power station was commissioned on 7 September 2012 but an inauguration ceremony led by Prime Minister Frank Bainimarama was held a week later on 14 September. Funding and loans for the project was provided by several organizations to include the China Development Bank (US$70 Million), Fiji Electricity Authority bonds (US$50 million), ADZ Bank (US$30 million). The 40 m tall dam diverts water from the Sigatoka River through a 3225 m long headrace/penstock tunnel to a power station along the Ba River to the southwest. The power station contains two 20.85 MW Pelton turbine-generators. The drop in elevation between the reservoir and the power station affords a gross hydraulic head (water drop) of 335.7 m.
