MEW to tender Hidd phase 3 consultancy

11 January 2002

The Ministry of Electricity & Water (MEW) is preparing to invite consultants to bid for the contract to provide services for the phase 3 expansion of the Hidd power and desalination complex. Tender documents for the consultancy contract are due to be issued by the end of the first quarter, once MEW has received final approval for the scope of works. This is expected to include design, tender evaluation, procurement and construction supervision.

Phase 3 calls for the installation of a 60 million-gallon-a-day (g/d) desalination plant utilising multi-stage flash (MSF) technology. The expansion will also comprise a 220-kV transmission system. The existing complex consists of two 140-MW gas turbines and four 7.5 million-g/d desalination units (MEED 16:2:01).

France's Alstom Poweris the prime contractor for the 700-MW phase 2 expansion. The scope of work calls for the installation of three 13/A2 gas turbines, as well as low nitrous oxide burners, an auxiliary bypass firing stack, and a 220-kV switchyard. Commissioning of the first steam turbine is scheduled for June, followed by the second in 2003 and completion by 2004. The consultant is Ireland's ESB International (MEED 21:9:01).

Phase 2 will boost the island's installed generating capacity of 1,260 MW by 30 per cent and provide sufficient steam for the MSF plant, which is scheduled for final commissioning in 2005.
