In the last one year leading Qualitrol, I’ve gained a front-row seat to one of the most pressing challenges in our energy sector. As the leading provider of transformer monitoring and safety solutions, we work closely with two key stakeholders: the manufacturers who build these essential grid components, and the utility executives responsible for keeping electrical infrastructure reliable and resilient.
In nearly every discussion—whether it’s strategizing production ramps or optimizing grid operations—the conversation inevitably turns to the ongoing transformer shortage. It always circles back to two core questions:
➡️ How can manufacturers scale up to address this surging demand?
➡️ In the meantime, how can utilities reduce risks and maximize the reliability of their existing assets?
Given the current policy landscape and market dynamics, a broader concern looms: Will domestic production ever fully bridge the gap? Drawing from my vantage point at this intersection of manufacturing and operations, here’s a grounded perspective on the crisis and potential paths ahead.
This isn’t a temporary disruption; it’s a deep-rooted supply chain issue with far-reaching implications.
Lead times for transformers have extended dramatically, often reaching two years or more—and up to three years for high-voltage units. Prices have surged significantly—between 45% and 95%, depending on unit size—amid escalating demand and input costs. The U.S. relies on imports for approximately 80% of its large power transformers and 50% of distribution transformer units, exposing a notable vulnerability in our energy security. Projections for 2025 indicate a 30% shortfall in power transformers and a 10% gap in distribution units, contributing to delays in grid expansions and project cancellations nationwide.
Compounding this, recent tariffs—such as those expanded tariffs on transformers, copper, and other key inputs—are driving up costs and disrupting supply chains. These measures, aimed at protecting domestic industry, are instead adding billions in expenses, inflating prices further, and slowing imports from key suppliers like Canada, Mexico, and Asia. While they encourage reshoring, the immediate impact is exacerbating shortages by making foreign units less viable without rapid domestic alternatives in place.
🔌 For Tech and AI Leaders: The explosive growth in data centers is clashing with grid limitations. Electricity demand from data centers is forecasted to rise by as much as 165% by 2030, potentially accounting for up to 9-12% of total U.S. power consumption. Without sufficient transformers to manage transmission and distribution build out, this could bottleneck AI advancements and tech infrastructure builds.

💡 For Energy and Utilities Professionals: Modernizing an aging grid is tough enough without supply constraints. Transformers are vital for integrating renewables, bolstering resilience against extreme weather, and supporting electrification trends. The shortage pits routine maintenance and replacements against new capacity needs, forcing tough trade-offs.
🏛️ For Policymakers: Our dependence on imports has been flagged as a national security risk by bodies like the National Infrastructure Advisory Council. Securing domestic supply chains is essential to maintaining U.S. economic competitiveness and energy independence.
Addressing this requires action on two fronts:
Boost Domestic Manufacturing: We need targeted incentives to expand U.S. production capacity. Reshoring is already underway, with major players investing heavily to bring operations stateside. For instance, Prolec GE is committing $140 million to double medium-power transformer capacity in Goldsboro, North Carolina. Hitachi Energy is accelerating with over $250 million in U.S. investments by 2027, including $106 million for a transformer components expansion in Alamo, Tennessee, WEG Transformers USA has built on its Missouri footprint with expansions in Washington, MO, though recent investments have focused more on vertical integration in Mexico and Brazil to support North American supply. Hyundai Electric (HD Hyundai Electric) is ramping up with $272.3 million to boost high-capacity transformer output by 30%, including expansions at its Montgomery, Alabama plant.
These efforts are promising, but reshoring isn’t happening at the pace needed to offset demand. Despite progress, import reliance remains high, and backlogs persist due to factors like skilled labor shortages, raw material constraints (e.g., grain-oriented electrical steel and copper), rising costs from tariffs, geopolitical tensions, and the time required to build and operationalize new facilities. Drawing from frameworks like the Inflation Reduction Act, tax credits, grants, and investments in critical materials—coupled with workforce training—could accelerate this.
Enhance Asset Management: With lead times so long, we can’t afford to idle. Advanced monitoring technologies—such as those offered by Qualitrol , which provide complete end-to-end solutions including sensors, analytics, and predictive tools—allow utilities to extend transformer lifespans, increase loading capacities safely, and predict failures before they occur. The technology exists today to deploy these systems widely across the grid. Currently, only about 25% of substation power transformers are equipped with online dissolved gas analysis (DGA) monitoring systems, leaving roughly 75% unmonitored and vulnerable to unexpected issues. Solutions like these can significantly mitigate the supply gap by enabling predictive maintenance that extends asset life through early detection of abnormalities and trend analysis, reducing the frequency of failures and the immediate need for new transformers. This not only bridges shortages by optimizing existing infrastructure but also enhances grid reliability with real-time situational awareness, proactive interventions to prevent outages, and improved load management—ultimately supporting a more resilient power delivery system amid growing demands. Real-time data analytics can optimize performance, helping bridge the supply gap without compromising safety or reliability.
The transformer shortage is more than an industry hurdle—it’s a pivotal factor in realizing our energy and technological goals. From my experience at Qualitrol, I’ve seen firsthand how proactive monitoring has helped clients navigate these constraints, but systemic changes are urgently needed.
