Demand from US data-center boom radiates out through factory supply chains

Data centers, once driven by the need for reliable power sources, are now being propelled by the growing demand for artificial intelligence. Giants such as Generac are investing heavily in manufacturing robust versions of their generators to power these AI-driven centers. With a projected $250 million expenditure by the end of next year, the company expects to add around 1,000 workers, marking a 10% increase in its workforce. The order backlog for these machines stands at a staggering $1.6 billion.

The ripple effect of this data center boom is being felt across various sectors. Manufacturers of cooling systems, electrical transformers, and construction machinery are all experiencing an increase in demand. These companies, in turn, are facing supply chain challenges as they strive to meet the escalating needs of data centers. From wire cables and pipes to cement and massive prefab metal walls, the list of affected industries is extensive.

The manufacturing sector as a whole is showing signs of recovery. U.S. factories added 5,000 jobs in July, bringing the total for the year to 31,000 - a stark contrast to last year's decline of 113,000 jobs. This positive trend is attributed to a surge in the construction of semiconductor plants, along with other factors.

However, despite the overall growth, there are lingering concerns about a potential bubble in the data center industry. While some sectors are thriving, others, particularly those dealing with consumer goods, are struggling due to high prices for food and gasoline. Generac's CEO, Aaron Jagdfeld, acknowledges this dichotomy, noting that while demand for their products remains strong, other areas of the market are facing headwinds.

The potential for a data center bubble has led to price hikes among manufacturers, as they strive to maintain delivery schedules. Companies like Siemens are taking proactive measures by signing multi-year contracts with customers to mitigate the risk of a downturn. Even smaller companies, such as Southeastern Hose, have experienced significant growth in demand from data center projects, which has led to a tripling of their revenue in the last five years.

However, they too are cautious about the potential risks and strive to balance the needs of their loyal customers with the new opportunities presented by the data center boom.
