GC Maintenance and Engineering and Peak Energy Sign PPA for 500 kWp Rooftop Solar at Rayong Facility

PRNewswire
Bangkok [Thailand], November 6: GC Maintenance and Engineering Company Limited (GCME), an engineering solutions leader within the PTT Global Chemical group, and Peak Energy, leading clean-energy platform operating across Asia-Pacific, today announced the signing of a Power Purchase Agreement (PPA) for a 500 kWp rooftop solar project at GCME's facility in Rayong, Thailand.
Under the long-term agreement, Peak Energy will design, finance, install, and operate the rooftop photovoltaic system. Once commissioned, the project is expected to generate approximately 730 MWh/year of clean electricity per year, avoiding ~350 tonnes of CO₂ annually. The system is structured as an on-site PPA, enabling GCME to purchase renewable electricity with no upfront CAPEX improving cost predictability during solar hours and supporting corporate carbon-reduction objectives.
The Rayong facility hosts key operations for GCME and is one of the primary sites where engineering and maintenance activities are carried out. Integrating rooftop solar at this location represents a concrete step toward more competitive, resilient, and climate-aligned operations.


GCME, as a key technical and operational arm of PTT Global Chemical, brings deep expertise in plant maintenance, safety engineering, and integrated asset support.
"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."
