Ningxia Power Multi-Energy Integration Demonstration Project Progressing Smoothly

As Yinchuan accelerates its development as a leading computing hub, SLG has successfully delivered six 28.5MW steam-driven lithium bromide absorption chillers for the project, which have now entered the commissioning stage.

As a key supporting energy infrastructure for the city’s computing hub strategy, the integrated energy station is designed to meet the high-load and continuous cooling demand of the “AI Port” data center, while also enabling efficient energy cascading for urban heating applications.

In total, the system provides up to 80MW of cooling capacity, ensuring stable year-round operation for high-density computing workloads that form the backbone of Yinchuan’s digital economy development.

Compared with conventional electric-driven cooling systems, SLG’s absorption technology uses steam as the driving source instead of mechanical compression, significantly reducing electricity consumption and carbon emissions, while improving overall system efficiency and sustainability.

A key feature of the project is its waste heat recovery and utilization system. During winter operation, recovered industrial waste heat is integrated into the district heating network, providing clean heating for surrounding urban areas covering approximately 3.5 million square meters.

Upon full commissioning, the project is expected to save around 30,000 tons of standard coal and reduce CO₂ emissions by approximately 80,000 tons annually, delivering both environmental and economic benefits.

From data center cooling to urban heating, the project demonstrates how integrated energy solutions can enable the development of a more efficient and sustainable computing hub.
