Renewable Energy

The world’s energy shortage crisis immensely affects the fluctuation of prices of natural gas and fuel, as well as the global economy. Many leading countries have encouraged and promoted the development and use of clean and renewable energy for sustainability.

Thailand is well aware of the global trend and the rise in the country’s energy cost, so the Thai government, in collaboration with the relevant public authorities has set out one of the country’s goals to be a low-carbon economy with net-zero carbon emissions.

As a result, the Energy Regulatory Commission of Thailand (ERC) has published the Regulation re: Procurement of Electricity from Renewable Energy under Feed-in Tariff (FiT) for the year 2022 – 2030, effective on 28 September 2022 (the “Regulation”), and the Announcements of the Invitation to Purchase the Renewable Energy under the FiT for all promoted renewables, i.e., Biogas (wastewater/ solid waste), wind, ground-mounted solar, and ground-mounted solar with battery energy storage system (BESS), effective on 1 October 2022 (the “Announcements”).

The key elements of the Regulation to promote the procurement of renewable energy are as follows:

Renewable Energy Power Producer Power Purchase Agreement Form Proposed Electricity to be sold FiT rate

(THB per Unit)

Biogas (wastewater/ solid waste)


Remark: fossil fuel is not allowed, except only at the commencement stage of the power plant operation.

·     Small Power Producer (SPP)*

·     Very Small Power Producer (VSPP)**

Non-Firm Not exceeding 90 MW THB 2.0724***

In addition, the Regulation also set out the target energy procurement quotas and the Scheduled Commercial Operation Date (SCOD) below:

Renewable Energy Proposed electricity to be sold (MW) per year of SCOD
