The power shortages, a consequence of the burgeoning expansion of AI data centers, are fueling a significant uptick in demand for power equipment, including gas turbines, energy storage systems, and microgrids, along with their associated manufacturing supply chains. The engineering machinery sector, which has ventured into this domain, has now emerged as a hotspot for market focus. Since 2026, relevant thematic ETFs have witnessed net inflows surpassing 4 billion yuan. Several fund managers have highlighted that AI data centers are capital-intensive endeavors, and their upstream construction fundamentally hinges on engineering construction and equipment provision. Over the forthcoming 3 to 5 years, the influence of power demand on the engineering machinery sector will not transform its inherent industry cycle traits; rather, it will reconfigure the cycle's structure, prolong its duration, and elevate its valuation threshold.
