Siemens Energy to invest US$1 billion as U.S. data-centre demand strains the power grid
Siemens Energy will spend US$1 billion to expand U.S. production of power-grid gear and gas turbine components, including a new Mississippi factory, amid surging demand from data centres.

Siemens Energy will invest US$1 billion in the United States to expand production of power-grid equipment and gas turbine components, citing a surge in demand from data centres. The move is part of a broader 6 billion euro investment plan and aims to ease strain on the U.S. electrical system as tech firms build large facilities across the country.
The package includes a new factory in Mississippi that Siemens says will be its largest facility for grid equipment worldwide. The plant is scheduled for completion in 2028 and, together with other capacity additions, should increase the company’s global output of large turbines by roughly 20 percent.
Why Siemens is betting on the U.S. market
Major technology companies are investing heavily in U.S. data centres, which require large, reliable power supplies. Government reports indicate data centres could account for about 12 percent of U.S. grid capacity within two years, up from much smaller shares in 2024. That rapid growth has pushed utilities, equipment makers and developers to secure new generation and transmission capacity faster than typical permitting and supply chains allow.
The U.S. is the hottest electricity market in the world at the moment ... And I don’t see this ending,
Christian Bruch, CEO, Siemens Energy
Siemens Energy generated a significant share of its orders last year from the U.S., and the company already makes about 22 percent of its sales there while employing 12 percent of its global workforce. The new investment is intended to meet near-term demand in North America and free up existing factories to serve other regions, such as Europe and the Middle East.
What Siemens will build and where
The Mississippi factory will produce power-grid equipment, a category that includes transformers and other hardware used to move electricity from generation sites to users. Siemens will also expand gas turbine component production, increasing the company’s ability to deliver large turbines for peaking and on-site generation at data centres and other high-demand facilities.
- Investment amount in the U.S.: US$1 billion
- Part of a larger 6 billion euro company-wide investment push
- New Mississippi factory, due for completion in 2028
- Estimated global turbine production increase: about 20 percent
- Siemens currently records around 20 gigawatts of generation tied to U.S. data centres
Implications for consumers, workers and the grid
For consumers, the investment could mean more resilient electricity in areas near new generation or upgraded transmission. Faster deployment of transformers and turbines can reduce bottlenecks that otherwise force utilities to delay new projects or ration power during peak demand periods. The impact will be local and incremental, rather than immediate and universal.
For workers, Siemens expects the U.S. expansion to create manufacturing jobs and support supply-chain roles in the region. The company has signalled it will reallocate some European production to better serve clients in other markets, while U.S. plants take on higher volumes destined for North America.
Supply chain and permitting remain constraints
Despite strong order pipelines, industry players continue to face supply chain bottlenecks and lengthy permitting processes that can delay projects. Companies building generation and transmission often negotiate reservation agreements to hold capacity while approvals and construction proceed, but those agreements do not eliminate logistical or regulatory hurdles.
Siemens’s strategy balances near-term manufacturing expansion with the need to serve regional markets more efficiently. The company plans to shift more U.S.-bound turbine production to North American facilities, allowing its Berlin turbine plant to focus on customers in Europe and the Middle East.
What to watch next
Look for updates on the Mississippi factory’s pre-construction approvals, hiring plans and the timeline for ramping production. Monitor how utilities and developers convert reservation agreements into completed projects, and whether other equipment makers follow Siemens with larger U.S. investments.
Longer term, the expansion underscores how data-centre growth is reshaping energy markets. The industry’s demand for reliable, dispatchable power is prompting faster investment in generation and grid hardware, which could affect electricity planning, local economies and manufacturing footprints.
Siemens Energy’s US$1 billion commitment is a clear signal that the company expects the U.S. market to remain a major driver of demand for years to come, even as supply-chain and permitting challenges persist.
