The draft Thailand Power Development Plan (PDP 2026) has passed sub-committee review but is not final. The first public hearing is on 8 September 2026. Under the draft, consumers can install their own solar and batteries and buy power from other sources, and private firms take a larger role in supply. Clean energy share is proposed at 65% to 80% by option, and the plan's clean-energy push is tied to CBAM and NDC 3.0 pressure on exporters. For a Thai SME, this is a planning signal, not an immediate cost change: if you are considering rooftop solar or battery storage, watch the final plan and its tariff rules. Hearing comments are open now if you want your views on record.
