Major transformer and grid component manufacturers announce over $1 billion in U.S. plant expansions to address long lead times and component gaps.
Surging demand for power transmission equipment from renewable developers, data centers, electric vehicle infrastructure, and grid modernization efforts has put pressure on U.S. supply chains. In response, major industry players including Hitachi Energy, GE Vernova, Hyosung HICO, and WEG are investing substantially in U.S. manufacturing capacity for transformers and other critical grid components. New facilities and expansions planned across several states aim to narrow the gap between supply and demand, with targeted improvements in transformer production, high‑voltage equipment and related supply networks. Long lead times that reached more than 140 weeks for some transformer types in 2025 have incentivized these investments, which could materially improve domestic component availability over the medium term.
Over $1 billion in new manufacturing investments from multiple global grid equipment suppliers will expand U.S. production capacity.
Growth in demand for generation step‑up transformers and high‑voltage gear has surged, driven by data center load growth and electrification trends.
Average delivery times for large transformer units reached historically long durations in 2025, prompting domestic build‑out.
Expanded U.S. production is expected to reduce reliance on imports and reduce supply chain risk for future grid projects.
These investments could lower equipment costs and improve project schedules for both transmission upgrades and HVDC installations.
“Investments in domestic production represent an effort to close the gap between supply and demand for critical grid components.”
CONCLUSION
Expanding U.S. manufacturing capacity for transformers and other grid hardware strengthens the backbone of grid modernization and supports timely deployment of large projects. Domestic supply growth helps mitigate one of the most persistent risks to high‑voltage and HVDC project engineering, reducing lead times and improving price stability. As grid demand continues to escalate, these upgrades to the supply chain are essential to keep infrastructure projects on schedule and reduce bottlenecks that can delay deployment of advanced transmission technology.
