SET-listed Global Power Synergy Plc (GPSC) expects installed capacity in 2019 to increase by 28% to 1,962 megawatts from domestic and foreign-based projects.
Chawalit Tippawanich, president and chief executive, said GPSC's power plants expected to be connected to the state grid in 2019 include the 1,285MW Xayaburi hydroelectric power plant and the 65MW Nam Lik 1 hydropower plant, both in Laos.
GPSC has ownership in those plants of 321MW and 26MW respectively, Mr Chawalit said.
The Central Utility Plant Project 4 (CUP-4) in Map Ta Phut, Rayong, will have its commercial operation date (COD) in 2019 with a capacity of 45MW for power and 70 tonnes per hour for steam.
In addition, GPSC will commence CODs for solar farms with a combined 39.5MW in 2019.
Mr Chawalit said the co-generation Nava Nakorn Electricity Generating Co in Pathum Thani will have its COD in 2020 with capacity of 125MW for power and 30 tonnes per hour for steam.
"60MW of total capacity is planned for the COD next year," he said.
GPSC's new COD capacity excludes the takeover deal between GPSC and SET-listed Glow Energy Plc. Mr Chawalit said the deal will conclude by March after the Energy Regulatory Commission (ERC) approved it on Dec 26.
The ERC exercised its legal authority to order Glow to sell the SPP 1 power plant in Map Ta Phut, Rayong to a third party before GPSC can acquire Glow.
"Glow's power plants are secured in GPSC's power portfolio in 2020," Mr Chawalit said. "Glow's power capacity totals 3,200MW nationwide."
He said GPSC is in talks with SET-listed Thai Oil Plc (TOP) to close a deal on a new power plant adjacent to TOP's refinery complex in Sri Racha, Chon Buri.
TOP is Thailand's largest-capacity oil refiner. It plans to develop a Clean Fuel Project (CFP) with an investment of US$4 billion (125 billion baht).
The project aims to expand oil refining capacity and improve productivity. It will include a power plant or energy recovery unit (ERU) worth a further $757 million.
GPSC has already received the provisional acceptance certificate from TOP and is expected to start construction in April and begin operations by 2023.
The ERU will run using residue crude oil or waste of refined oil from the CFP, with electricity generation of 250MW and 175 tonnes per hour of steam.
GPSC is also in talks with PTT Exploration and Production Plc to develop a gas-fired power plant in Myanmar. The deal is expected to conclude in March.
