Thailand's energy committee, chaired by Deputy Prime Minister Pakorn Nilprapunt, has resolved to restructure the contract terms and pricing arrangements of existing solar and wind power purchase agreements (PPAs), with the stated aim of bringing electricity procurement costs closer in line with current market conditions and government policy, and ultimately lowering costs for end consumers.
Under the plan, each legacy PPA will be extended for one further cycle matching its original renewal period — typically three or five years — during which the purchase price will be renegotiated; automatic renewals beyond that point will be discontinued.
For large independent power producers (IPPs), the committee has also resolved to set up a dedicated sub-committee to review the Availability Payment and Energy Payment structures under their PPAs, aiming to reduce those costs specifically.
Thailand's Energy Policy and Planning Office has set a target of raising clean energy's share of the overall energy mix to 50% by 2026, up from roughly 30% currently. Beyond the PPA restructuring, the country's broader renewable energy incentive package is projected to stimulate more than 270 billion baht in combined investment, and the Government Savings Bank has earmarked part of a 100-billion-baht soft loan program specifically to support solar installations.
Industry forecasts point to 1.2 to 1.8 gigawatts of new solar capacity coming online this year, with commercial and industrial distributed solar accounting for about 36% of the market.
Analysts note that renegotiating legacy PPAs involves balancing existing investors' interests against policy stability, and how the government strikes that balance between cutting electricity costs and keeping renewable energy an attractive investment will be the key factor in whether the implementation details land smoothly — a process the market is watching closely.
