Doosan’s offer covers four gas turbines, each of 100 MW, the installation of two heat recovery steam boilers and the balance of plant works. The extension will take about 21 months to complete.

The client is Gulf Total Tractebel Power Company (GTTPC), which was formed in 2000 to acquire and expand the existing 225-MW, 29 million-gallon-a-day (g/d) Taweelah A-1 co-generation plant on a build-own-operate (BOO) basis (MEED 11:8:00).

Under the terms of the 2000 contract, GTTPC agreed to expand the A-1 station to 1,350 MW and 84 million g/d, using Frame-9 gas turbines manufactured by the US’ General Electric and multi-effect distillation units from France’s Sidem.

The shareholders in GTTPC are Abu Dhabi Electricity & Water Authority with 60 per cent, and France’s TotalFinaElf and Tractebel of Belgium with 20 per cent each.
