Fiji Electricity Authority (FEA) has reissued two solicitations, and extended bidding deadlines, for construction of civil works and of powerhouse and transmission works for the 40-MW Nadarivatu hydroelectric project.
The deadline for two separate solicitations is extended to May 6 from April 4. The April 4 date had been an extension from earlier deadlines.
The proposed project includes a 35-meter-tall weir on the Sigatoka River catchment at Korolevu; 3.5 kilometers of tunnel and penstock, and a powerhouse on the Ba River containing two 20-MW Pelton turbine-generators for a head of 300 meters.
