Fiji seeks design to expand 80-MW Wailoa

Fiji Electricity Authority (FEA) seeks consultants to design and manage projects to add a penstock and powerhouse, boosting the capacity of the 80-MW Wailoa hydroelectric project on Fiji’s Viti Levu Island. Expressions of interest are due October 13.

Wailoa’s four 20-MW turbines are fed by a tunnel from Monasavu Dam. However, the project experiences relatively high head losses when four units are running, limiting maximum station output to 72 MW.

FEA seeks installation of a second tunnel/penstock for the project to minimize head losses and maximize four-unit operation. The free-standing penstock is to provide additional generation of 17.5 gigawatt-hours per year and the additional 8 MW of capacity.

The utility said installation of the second penstock also facilitates the opportunity to install a fifth 20-MW generating unit at the project, which would provide sufficient peaking capacity to satisfy generation spinning reserve requirements. That work would involve supply and installation of a fifth unit in an additional powerhouse, with provision for a bay to install a sixth unit in the future.

Consultant services for the two facets of the solicitation include detailed engineering design, preparation of bidding documents, evaluation of bids, awarding of contract, and project management including construction supervision. Consultants are expected to be recruited by first quarter 2007, with project implementation to be in fiscal years 2007-2009.

Expressions of interest and qualifications are due to the address below by October 13. For information, contact Tuvitu Delairewa, Fiji Electricity Authority, 2 Marlow St., Suva, Fiji; (679) 3224-185; Fax: (679) 3316-773; E-mail: tdelairewa@fea.com.fj.
