Background

TPI Polene Power PCL (TPIPP) of cement maker TPI Polene operates a 150 MW coal pant in Tapkwang, Kaeng Khoi district. The company received environment and health impact assessment (EHIA) approval in 2017.

In January 2019, TPI Polene said the plant had begun commercial operation. TPI Polene Power PCL's power station is sometimes referred to as Coal-PP-150MW (TG8).

PPA

TPIPP's 2019 annual report listed the following:

"Coal-PP-150MW (TG8) has been completed and commenced commercial operations and sold electricity to TPI Polene PCL on January 25, 2019. Under the Coal-PP-150MW Power Purchase Agreement between the Company and TPI Polene Plc, Coal-PP-150MW is obligated to supply and TPIPL is obligated to offtake at least 30% of power generated by Coal-PP-150MW each year to TPIPL. The Company shall receive a monthly power tariff from TPIPL at the same rate per kWh of power according to the time of use rate (TOU) as the average tariff rate at which TPI Polene Plc purchases electricity from the PEA each month without charging the highest energy charge (Demand Charge), subject to any value-added tax. The power tariff is determined based on the actual amount of power delivered each month. The term of Coal-PP-150MW Power Purchase Agreement will end upon the expiration of the lease agreement for Coal-PP-150MW entered into between the Company as lessee and TPIPL as lessor. The lease agreement will expire in July 2042. Coal-PP-150MW has been granted a promotion certificate from the BOI, which entitles it to a number of benefits including exemptions from certain taxes."

Opposition

In November 2018, a group of local people said the project's EHIA study was carried out without gathering sufficient feedback and other information. They threatened to take a legal action against the Energy Regulatory Commission if it granted the company a license for the plant. The group also said TPI Polene had already started building the plant despite not having the license, which could make it liable for certain penalties.

In December 2019, about 50 villagers from Mittraphap and Muak Lek sub-districts in Saraburi province filed a lawsuit against TPI Polene Power Plc at the Central Administrative Court. The villagers said the EHIA report did not cover the plant's impact on dairy farmers, tourism, society, and health.

Coal-free plans

TPI Polene Power Plc (TPIPP) is Thailand's largest waste-to-energy (WTE) project developer and operator by capacity. In 2021, it vowed to become a coal-free power generation company by 2025 with plans to replace fossil fuels with refuse-derived fuel (RDF). At the time of the announcement, electricity supplied by coal-fired power plants accounted for half of the company's total installed capacity of 440 megawatts. The company expects the fuel replacement plan to involve spending of 5.5 billion baht between 2022 and 2025.

In June 2022, the company reiterated their carbon-neutral plans. According to International Finance, the company was looking to maximize their use of refuse-derived fuel (RDF) and other 'clean and green' developments in Southern Thailand.

In October 2022, TPIPP discussed increasing the burning of municipal solid waste (MSW) at their power stations. They stated that their operations would be carbon negative by 2026.

In June 2023, TPI Polene reported that 10% of the coal-fired power plant had been fueled with municipal waste in 2022, and it was expecting to replace 100% of its coal fuel with municipal waste fuel in 2025.

In March 2024, TPI Polene announced a plan to achieve 100% renewable energy generation by 2026. Coal would reportedly be replaced by a combination of refuse-derived fuel, solar, wind, and waste heat.

As of August 2024, TPI Polene replaced approximately 14% of coal with municipal waste.
