GC Maintenance and Engineering Company Limited (GCME), part of the PTT Global Chemical group, has signed a Power Purchase Agreement (PPA) with Peak Energy for a 500 kWp rooftop solar project at its Rayong facility in Thailand. Under the long-term agreement, Peak Energy will design, finance, install, and operate the system.
Once operational, the project is expected to generate about 730 MWh of clean electricity annually, reducing approximately 350 tonnes of CO₂ each year. Structured as an on-site PPA, it allows GCME to source renewable power without any upfront investment. The system will help stabilize energy costs during solar production hours while advancing the company’s carbon-reduction goals.
“This agreement reflects GCME’s pragmatic and forward-looking approach to energy management as part of the PTT Global Chemical group,” said Gavin Adda, CEO of Peak Energy. “In a grid parity market like Thailand, where the energy market is highly competitive, site-level solutions that offer long-term price visibility for industrial players are increasingly relevant. This project has been structured to integrate seamlessly into existing operations, with a focus on safety, reliability, and measurable impact. We appreciate the trust placed in this collaboration and remain committed to supporting GCME’s operational and sustainability priorities over time.”
