Cooling, Water and Data-Centre Construction Supply Chain — 2026-09-04
Data centre construction faces a severe bottleneck as electrical equipment lead times stretch to five years and skilled labor shortages intensify, with contractors reporting record backlogs. Simultaneously, water usage controversies escalate in the US, highlighted by a major leak in drought-stricken Oklahoma and new legislative transparency bills in California. In China, liquid cooling manufacturers report orders booked through year-end as domestic AI infrastructure demand accelerates.
Cooling, Water and Data-Centre Construction Supply Chain — 2026-09-04
Top developments
US Transformer Lead Times Stretch to Five Years
Recent industry reports indicate that transformer delivery timelines have stretched from 24–30 months pre-2020 to as long as five years today, creating a critical constraint for data centre developers. A survey cited by Giga Energy places average switchgear lead times at 44 weeks, while Hitachi Energy notes that 44% of data centre leaders report utility wait times exceeding four years. This shortage directly impacts the ability of hyperscalers to energize new AI halls, forcing delays or expensive workarounds in power distribution infrastructure.
Water Leak in Drought-Hit Oklahoma Sparks Outcry
A data centre linked to AI and bitcoin mining operations in El Reno, Oklahoma, released more than three million gallons of water after a private water line failed on September 2, 2026. The incident occurred during severe drought conditions, intensifying community opposition and political scrutiny regarding industrial water use. This event underscores the growing reputational risk for operators in water-scarce regions, potentially influencing future permitting decisions and cooling technology choices.
Chinese Liquid Cooling Orders Booked Through Year-End
Chinese media reports indicate that liquid cooling manufacturers, including key suppliers like Envicool and Shenling Environment, have production orders booked through the end of 2026. The surge is driven by the deployment of high-power AI computing clusters where traditional air cooling is insufficient. The domestic liquid cooling market size reached 15.98 billion yuan in 2025, with global AI computing liquid cooling markets projected to exceed 100 billion yuan in 2026. This momentum validates the shift toward liquid immersion and direct-to-chip solutions among Asian vendors supplying Nvidia partners and local hyperscalers.
Skilled Labor Shortage Chokes Data Centre Construction
The construction sector faces an acute shortage of skilled workers, particularly electricians and fiber-optic technicians, threatening to stall the $725 billion AI buildout. Estimates suggest the US is short by 58,000 workers needed to install fiber-optic cables, while training periods for electricians extend up to five years. Contractors are increasingly offering enhanced benefits and recruiting from adjacent sectors like telecommunications to fill gaps, but the labor wall remains a primary constraint alongside hardware shortages.
Local view
US Media Focus on Water Transparency and Political Pushback Local US media are heavily focusing on the lack of transparency regarding data centre water usage. California lawmakers have reached a compromise on legislation to regulate energy use, while two new bills aim to force disclosure of water consumption, challenging Governor Newsom’s previous vetoes. In Texas, state senators held hearings questioning the lack of information about water impacts from data centres. Meanwhile, Commerce Secretary Howard Lutnick’s claim that data centres "don’t use water" has drawn sharp criticism from environmental journalists and local communities facing drought restrictions.
Chinese Financial Media Highlight Liquid Cooling Momentum Chinese outlets such as Sina Finance and Financial World are reporting that liquid cooling stocks are surging, with companies like Envicool hitting daily limits. Reports emphasize that the transition from air to liquid cooling is no longer optional but mandatory for next-generation AI servers, driving a "trillion-dollar" supply chain boom. The narrative focuses on the readiness of domestic vendors to meet the immediate demand for CDUs (Coolant Distribution Units) and cold plates.
Context & numbers
- Transformer Lead Times: Up to 5 years for large power transformers in constrained markets, up from 24–30 months pre-2020.
- Switchgear Lead Times: Average of 44 weeks.
- Labor Gap: Approximately 58,000 workers short for fiber-optic installation; electrician training takes 5 years.
- Vertiv Backlog: Over $15 billion, with liquid cooling becoming the default design standard.
- China Liquid Cooling Market: Reached 15.98 billion RMB in 2025; global AI computing liquid cooling market projected to exceed 100 billion RMB in 2026.
- Construction Growth: Data centre construction is up 46% year-over-year, serving as the primary driver of US non-residential building growth.
On the radar
- California Water Disclosure Bills: Two new bills requiring data centre water usage transparency are heading to Governor Newsom’s desk, following his previous veto of similar measures. Watch for potential signing or further veto.
- EPA Public Comment Proposal: An EPA proposal may restrict public access to information about proposed AI data centres, potentially limiting community input during permitting.
- Denver Lawn Watering Incident: Viral reports of a Denver data centre watering its lawn during extreme drought restrictions may trigger local enforcement actions or stricter municipal ordinances on recycled water use.
