Transformers: Pricing, Procurement, and Best Practices

Main Factors Affecting Power Transformer Prices (2015–2025)

The cost of power transformers has seen a steady rise over the past decade, driven by fluctuating raw material prices, evolving technology standards, and supply chain challenges. These factors have not only increased prices but also extended delivery times, reshaping the market landscape.

Raw Material Cost Effects

The volatile prices of copper and steel have played a major role in driving up transformer costs between 2015 and 2025. Gerry Yurkevicz, managing director of the worldwide Energy Group at Global Insight, explains:

"We view transformer prices as a function of both production costs and market activity, where costs are assumed to exert the dominant influence over transformer prices through time."

Copper prices have been particularly unstable. In earlier years, copper was priced at approximately $1.54 per kilogram, significantly below its historical average of $2.42 per kilogram. By June 2025, global copper prices soared to $9.51 per kilogram - a 1.5% increase over the prior period. In North America, prices reached $9.63 per kilogram, while in Northeast Asia, they climbed to $10.49 per kilogram. The global copper market itself expanded from $110 billion in 2020 to an anticipated $155 billion by 2025, reflecting a compound annual growth rate of 7.2%.

Steel prices have followed a similar rollercoaster. Between Q1 2020 and Q1 2021, structural steel costs jumped by 43%, with an additional 82% spike by the end of 2021. However, recent trends show a slight easing, with prices dipping 4.56% since January 2025 and a year-over-year decline of about 10.5%. These rising material costs, coupled with growing demand in regions like Asia and the Middle East, have further fueled transformer price hikes.

These raw material trends are only part of the story, as technological advancements have also added to production costs.

Technology Changes and Efficiency Gains

The introduction of updated efficiency standards in 2016 by the Department of Energy (DOE) significantly impacted transformer production costs. These standards increased efficiency requirements to between 98.70% and 99.55%, compared to the 2010 range of 98.36% to 99.49%. Meeting these new benchmarks required higher-grade materials, such as premium steel and copper, leading to cost increases.

According to data from Maddox Industrial Transformer, the cost of new 3-phase liquid-filled transformers rose by an average of 16.5% between 2015 and 2016. For instance, a transformer with a 225 kVA rating that cost $7,100 in 2015 jumped to $8,000 in 2016 - a 12.7% increase. Larger, higher-rated transformers experienced similar price escalations, highlighting the financial impact of these efficiency improvements.

Looking ahead, proposed DOE standards for 2027 are expected to mandate the use of amorphous steel cores in nearly all transformers, replacing traditional grain-oriented electrical steel. Industry projections suggest this shift could drive transformer prices up by 50–125% or more. On top of this, advancements in smart transformer technology - such as IoT sensors and digital monitoring systems - are further increasing costs while offering features like enhanced performance and predictive maintenance.

These technological shifts are occurring alongside significant supply chain challenges.

Market and Supply Chain Issues

Supply chain disruptions have made transformers harder to source and more expensive to purchase. Peter Ferrell, Director of Government Relations at the National Association of Electrical Manufacturers (NEMA), describes the situation:

"Delivery of a new transformer ordered today could take up to three years. Five years ago, that wait time was four to six weeks."

The COVID-19 pandemic exacerbated these challenges, slowing raw material supplies. During this time, the cost of Grain Oriented Electrical Steel (GOES) doubled, and copper prices rose by about 50%.

Demand surges from renewable energy projects and electric vehicle (EV) infrastructure have added further pressure. In the U.S., demand for distribution transformers is projected to grow by 260% by 2050 compared to 2021 levels, as 55% of existing transformers are over 33 years old. Global trade policies and rising shipping costs have also complicated the market, with copper prices remaining highly sensitive to policy shifts and trade tensions. These combined factors have contributed to an overall transformer price increase of 60–80% since January 2020.
