Our Ziyang Brewery in Sichuan, China became the China beer industry’s first to install electric boilers using hydropower in 2023. The electric boilers replaced the natural gas ones to generate steam with a newly constructed power generation and storage system. Leveraging the peak-valley power pricing to achieve cost-effectiveness, the system generates and stores the heat by the off-peak hours electricity (the price is 72% lower than peak hours) to meet the brewery’s steam production needs throughout the day.

In addition to the power cost-effectiveness, we strategically took a sustainable project model, “Energy as a Service (EaaS)”, to capture the transition opportunity with financial benefits. We have formed a partnership with the selected service provider for a 20-year procurement contract who invested approximately RMB40 million in the infrastructure and equipment for the whole system, with a building area of around 3,000 square meters within Ziyang Brewery.

The project includes the construction of a new 25 MW electric steam boiler, two 1,000 m3 high-pressure energy storage tanks with a daily steam supply capacity of 250 tons, a new 25.5 MW high-voltage distribution system, a new purified water system, and an intelligent energy management platform. The project is expected to realise a reduction of approximately 7,000 tons of CO₂ emissions.
