Plans to develop some 12 GW of new capacity across Thailand are under discussion in what is expected to be a $6 billion tender to be launched next year.

Thailand is in consultation with potential investors including independent power producers (IPPs), lenders and advisers, on the structure of the power purchase agreements but is thought to be prepared to offer long-term deals in order to attract foreign investment.

The Energy Ministry’s policy and planning office is preparing for the bidding process within the next few months for the planned 12 GW of projects to be built in stages over around five years starting in 2011.

State-owned Electricity Generating Authority of Thailand (EGAT) is expected to build up to half of the new capacity, the rest will be developed by domestic and foreign IPPs.
