Thailand Introduces Utility Green Tariff to Promote Renewable Energy

Thailand Introduces Utility Green Tariff to Promote Renewable Energy

The initiative aims to encourage businesses to adopt green energy at 4.21 baht per kilowatt-hour.
Thailand has implemented a new utility green tariff (UGT) strategy, requiring companies to pay a rate of 4.21 baht per kilowatt-hour for renewable energy usage.

This tariff is slightly above the standard rate of 4.15 baht and applies only to businesses with campaigns to reduce carbon dioxide emissions, according to Poonpat Leesombatpiboon, secretary-general of the Energy Regulatory Commission (ERC).

The 4.15-baht tariff, effective from January to April, remains in place for calculating standard monthly electricity bills.

Companies interested in the renewable energy tariff need to sign one-year power purchase agreements with one of the major electricity providers: the Electricity Generating Authority of Thailand (Egat), the Metropolitan Electricity Authority (MEA), or the Provincial Electricity Authority (PEA).

Approximately 2 billion kilowatt-hours of renewable energy are being prepared for distribution by April, as stated by Mr. Poonpat.

From January 2nd to February 28th, the three electricity agencies are registering companies interested in this clean energy offer, with 600 million kilowatt-hours already requested by electronics, chemical, and petrochemical companies.

These requests also include malls and financial companies serviced by the MEA.

The green tariff rate, designated as 'UGT 1', encompasses electricity sourced from seven hydropower dams managed by Egat, boasting a generation capacity of 1,135 megawatts to ensure the availability of 2 billion kilowatt-hours annually.

Further distinctions in renewable power tariffs, known as 'UGT 2', are currently under consideration by the ERC, potentially encompassing 4.8 gigawatts of power from specified renewable sources under the first-phase renewables scheme.

Egat is also extending its renewable energy supply through floating solar farms.

Deputy Governor for Strategy, Tawatchai Sumranwanich, announced plans to develop a total of 17 solar farms with a combined capacity of 2,725 megawatts at the reservoirs of six hydropower dams.

Two of these projects, at the Sirindhorn Dam and Ubonrattana Dam, are already operational, while the remaining developments are scheduled between 2025 and 2030.
