To strengthen its green competitiveness, Vietnamese steel giant Hoa Sen Group has partnered with Singapore’s SP Group to deploy a Cooling-as-a-Service (CaaS) system, combined with rooftop solar power.
The initiative is expected to reduce the company’s cooling electricity use by over 30% annually and cut carbon emissions by 14,000 tons.
Hoa Sen ramps up green shift with rooftop solar, smart cooling
Under the agreement, SP Group will install a 1,900 refrigeration-ton CaaS system at Hoa Sen’s two key steel sheet plants in Phu My and Nghe An, with operations set to begin in Q2 of 2026. Rather than investing in cooling equipment, Hoa Sen will pay for the cooling service, saving on infrastructure and capital costs.
