Poonpat Leesombatpiboon, Secretary-General of the Energy Regulatory Commission (ERC) revealed that on June 10, the ERC has approved the draft announcement regarding the invitation to purchase electricity from the citizen solar rooftop projects. The draft is set to be opened for public hearing from stakeholders and the general public before further review and improvement to ensure suitability and completion.
This action follows the resolution of the National Energy Policy Council (NEPC) on April 29, 2026, which approved the framework to promote the production of solar rooftop electricity in households and assigned the ERC to issue the necessary regulations and announcements for electricity purchase by June 2026.
The promotion of rooftop solar power generation (Solar PV Rooftop) in households is a key mechanism providing opportunities for public participation in electricity generation and energy management, as well as reducing long-term energy costs. The initiative has a purchase limit of 500 megawatts, with a maximum offering of 5 kilowatts per purchase meter, a purchase rate of THB 2.20 per unit, a purchase term of 10 years, and a system connection required by 2027.
Moreover, the commission has also set qualifications for the very small power generation applicants, which include procedures and timeframes, responsibilities of distribution utilities, associated system connection costs, and the draft power purchase agreement.
Comments can be done through the ERC Office’s website, www.erc.or.th, from June 10-23, 2026, totaling 14 days. Interested parties can study the details and provide their opinions through this channel to ensure the draft announcement is appropriate, transparent, and beneficial to all sectors.
Krungsri Securities (KSS) viewed the public hearing as a positive factor for solar rooftop distribution and installation businesses, particularly Gulf Development Public Company Limited (SET: GULF), whose revenue from this business is less than 1%, and Gunkul Engineering Public Company Limited (SET: GUNKUL), which has a revenue share from this segment at around 6 – 7%.
The move also reflects the government’s continuous push toward liberalizing the power sector for the general public, which will gradually unlock further business opportunities—including increased smart meter installation for electricity retailers, as well as investments in transmission systems and electricity infrastructure to support more decentralized power generation and trading.
From an investment perspective, KSS maintains a bullish view on utilities, picking GULF with a 2026 target price of THB 74 and Global Power Synergy Public Company Limited (SET: GPSC) with a target price of THB 48 as top picks, citing financial strength and the opportunity to benefit from new Independent Power Producer (IPP) contract extensions under the country’s new Power Development Plan (PDP 2026).
The Investment Analysts Association (IAA Consensus) issued a highest target price for GUNKUL at THB 5.65.
