US EditionSoutheast Asia's First Industrial Heat Battery Now Operating in Thailand, Built by Rondo Energy and SCG
The 33 MWh heat battery delivers 2.3 MWth continuous steam to generate 24-hour clean electricity, supporting SCG's Net Zero 2050 goal and regional industrial decarbonization.
- On Nov. 13, 2025, Rondo Energy and SCG Cleanergy inaugurated Southeast Asia's first Rondo Heat Battery at SCG's cement plant in Saraburi Province, Thailand, announcing it began operation.
- Aligned with SCG's Net Zero 2050 commitment, the deployment aims to enhance energy efficiency and industrial decarbonization while delivering low-cost clean energy across Southeast Asia, SCG Cleanergy said.
- Built as a 33 MWh Rondo Heat Battery, the system delivers 2.3MWth continuous steam from the grid and a floating solar farm, driving a steam turbine for 24-hour clean electricity.
- Using local suppliers in Thailand, the partners built the unit entirely with eight months construction time, following Rondo's California commissioning and supporting Thailand's clean-heat manufacturing hub emergence.
- Rondo's modular design positions the technology to scale from 33 MWh to >1GWh using mass‑manufactured brick and wire heating elements and a common supply chain for surging industrial decarbonization demand.
