However, the Electricity & Water Ministry scrapped the tender to protect itself from the Kuwaiti dinar's fall against the US dollar.
Under the new tender, the ministry allowed bidders to price up to 60 per cent of their commercial bids in foreign currency.
The previous tender had called for 100 per cent pricing in dinars.
The gas-fired plant will have power capacity of 2,000MW (MEED 29:4:09).
