Power Plant
The Company focuses on becoming a leader in clean energy through the operation of power plants that utilize advanced and environmentally friendly technologies, in response to the National Energy Plan (2065–2070) and to achieve Carbon Neutrality by 2050.
Currently, the Company operates power plant businesses with fuel management aligned with the Circular Economy approach as follows:
- Waste-to-Energy (WTE) & RDF: Six waste-fueled power plants with a total installed capacity of 400 megawatts (including a 150-megawatt power plant currently under a transition project from coal to 100% waste fuel, which is expected to be completed in early 2026), and one community waste-to-energy power plant project under the community waste management for electricity generation program, located in Koh Taeo District, Songkhla Province, with an installed capacity of 9.9 megawatts.
- Waste Heat Recovery (WHR): Two waste heat power plants with an installed capacity of 20 megawatts each, totaling 40 megawatts. These plants utilize technology that captures excess hot air from the cement production process at the cement plant of TPI Polene Public Company Limited to produce steam for electricity generation. This process also reduces the temperature of the hot air before it is released into the atmosphere, thereby enhancing eco-efficiency.
- Renewable Energy Mix (Solar Power): Renewable energy power plants under the Solar Farm and Solar Rooftop projects with a combined installed capacity of 81.4 megawatts, aimed at enhancing the diversity of energy sources and reducing dependence on fossil fuels. The electricity generated is used within affiliated industrial operations, including cement manufacturing plants, construction materials plants, and health-related industry plants located in Kaeng Khoi District, Saraburi Province, as well as the fiber cement plant of TPI Polene Public Company Limited located in Chaloem Phra Kiat District, Saraburi Province. The Company operates solar power plant projects in Saraburi Province as follows:
- Projects 1 and 2: Ground-mounted solar power generation projects with an installed capacity of 52.2 megawatts, producing and supplying electricity to the cement plant in Saraburi Province and preparing to supply electricity to other factories in the area. The projects have been completed and commenced Scheduled Commercial Operation Date (SCOD) in 2025.
- Project 2: A solar rooftop power generation project with an installed capacity of 5.1 megawatts located in Chaloem Phra Kiat District, Saraburi Province, generating electricity for sale to the Fiber Cement plant of TPI Polene Public Company Limited. The project has been generating and selling electricity commercially since August 2024.
- Project 3: A ground-mounted solar power generation project with a power generation capacity of 9.6 megawatts. The project is currently under construction and is expected to commence operations and commercial electricity sales by the second quarter of 2026.
- Project 4: A ground-mounted solar power generation project with a power generation capacity of 14.48 megawatts. The project is currently under co
- Joint Venture Project with Electricity Generating Public Company Limited (EGCO): The Company has established E & T Renewable Energy Company Limited as a joint venture, with a registered capital of Baht 2,000 million and a paid-up capital of Baht 500 The objective is to operate power plant businesses, including solar power plants and ground-mounted solar power plants integrated with a Battery Energy Storage System (BESS). E & T Renewable Energy Company Limited has participated in the bidding for renewable electricity generation projects under the Feed-in Tariff (FiT) scheme for the period 2022–2030 for the group with no additional fuel costs. It was selected as the winning bidder for six projects, with a total proposed electricity supply capacity of 280.50 megawatts. Each project is expected to gradually commence Scheduled Commercial Operation Date (SCOD) starting from 2028 onwards.
- Community Waste-to-Energy Power Plant Project: One community waste-to-energy power plant under the community waste management for electricity generation program located in Mukdahan Province, with an installed capacity of 9.9 megawatts, and a ground-mounted solar power plant (Solar Farm) with an installed capacity of 24.2 megawatts in Saraburi Province, both of which are currently under construction.
