Power transformer prices, 5 to 300 MVA

Price per MVA benchmarks

These are the public benchmarks for new large power transformers in the US market, as compiled by NextMSC from the National Laboratory of the Rockies (NLR) and the US International Trade Commission. They are indicative and vary with rating, voltage, origin and customization.

Large power transformer prices by MVA at the benchmark

Multiplying the USITC benchmark of $15,000 to $21,000 per MVA by the rating gives the budget range for a standard large unit. Treat it as the floor for a plain two winding transformer. Load tap changers, extra high voltage windings, special impedance and short delivery all push the real price above it.

Smaller substation transformers, 5 to 25 MVA

Units below about 25 MVA cost more per MVA than large power transformers. Electrical Trader reports that 1 to 25 MVA units were priced at $30,000 to $40,000 per MVA in mid 2019, and that prices rose 70 to 100 percent after 2020. The US producer price index for power and distribution transformers rose 91.4 percent from January 2020 to July 2026. The third column applies that index move to the 2019 range, as a rough current budget.

Computed from the two published figures above. An index of producer prices is not a quote, and a single project can land well outside this range.

Overseas factory prices you will see online

Many top search results for transformer prices are Chinese manufacturer blogs quoting ex works prices, which exclude ocean freight, the Section 232 tariff, US standard testing and delivery. One lists 1 MVA at $7,000 to $15,000, 2.5 MVA at $15,000 to $28,000, 5 MVA at $45,000 to $65,000, 10 MVA at $70,000 to $120,000 and 20 MVA and up from $180,000. Another lists 1 to 10 MVA at $50,000 to $300,000 and 10 to 100 MVA at $300,000 to $2 million.

Electrical Trader reports a 15 percent tariff on the full customs value of imported grid equipment under Section 232 from April 2026, due to rise to 25 percent after 2027. Add it, freight and ANSI or IEEE testing to any ex works figure before comparing it with a US delivered quote.

How prices moved since 2020

The US Bureau of Labor Statistics producer price series for power and distribution transformers, as compiled by NextMSC. Between 2019 and 2025 the annual average rose 80.6 percent. Year on year to July 2026 it was up 8.7 percent.

Lead time next to price

For most buyers the date matters as much as the price. Published lead times for new units are below.

What moves the price

Core steel and copper make up about half the cost of a large power transformer, about a quarter each, and logistics add 3 to 20 percent. Beyond materials, these choices move the number.

• Voltage class and BIL. A 138 kV or 345 kV winding needs more insulation, larger bushings and a bigger tank than a 69 kV one.
• Tap changer. An on load tap changer adds cost and, at 80 to 90 weeks, can set the delivery date.
• Cooling class. Forced oil and forced air (OFAF) cooling adds about 15 to 25 percent over natural cooling, per one manufacturer price guide.
• Dry type against liquid filled. Cast resin units carry a 20 to 40 percent premium per that guide, and another puts it at 50 to 120 percent at 5 MVA.
• Type tests. Impulse, sound and heat run tests add about 5 to 10 percent, mostly on high voltage units.
• Origin and tariff. US made, Mexican, Korean and European units carry different prices, duties and lead times.
• Delivery date. A unit in stock or in a production slot that fits your date is worth more than one that ships in three years.

Used, reconditioned and new surplus

Electrical Trader puts used and reconditioned substation equipment at typically 30 to 60 percent of new, fully refurbished equipment with a warranty at 50 to 70 percent, and as is equipment at 20 to 40 percent. Moving a used substation transformer adds real cost, dismantling at the original site at $100,000 to over $1 million, transport at $50,000 to $500,000 or more, and reassembly and commissioning at $200,000 to over $3 million.

New surplus, a unit built for a project that changed, is often the best of both, a new transformer that ships in weeks. We search new, surplus and reconditioned stock together for every request.

Whole substation costs for context

The transformer is one line in a substation budget. Published ranges for complete substations are below, with civil works and installation at 40 to 60 percent of equipment cost.

Why supply is tight

NLR reports that more than 80 percent of US large power transformer demand is met by imports. US imports of liquid filled transformers above 100 MVA rose from 617 units in 2019 to 2,268 units in 2025, with Mexico, Brazil and South Korea supplying 57 percent of the 2025 units. New US plants are coming, including Hitachi Energy in South Boston, Virginia and Gallman, Mississippi, where production is scheduled for 2029, but they arrive after most current projects need their units.

How much does a power transformer cost

The most cited US benchmark for a new large power transformer is $15,000 to $21,000 per MVA, so about $1.5 to $2.1 million for 100 MVA. Highly customized 100 MVA units run up to about $4 million, and smaller substation units cost more per MVA.

How much does a substation transformer cost

Units of 1 to 25 MVA were $30,000 to $40,000 per MVA in mid 2019, and producer prices have risen about 91 percent since January 2020. A complete small distribution substation of 5 to 10 MVA is typically $1 to $3 million.

What is the price per MVA of a transformer

$15,000 to $21,000 per MVA for new large power transformers per the USITC benchmark, and more per MVA for smaller units.

How much does a 100 MVA transformer cost

About $1.5 to $2.1 million at the USITC benchmark, up to about $4 million for a highly customized unit, before freight and installation.

Why have transformer prices gone up

Core steel and copper are about half the cost, demand from utilities, data centers and renewables has outrun factory capacity, and most large units are imported. The BLS producer price index for transformers is up 91.4 percent from January 2020 to July 2026.

Are used power transformers cheaper

Used and reconditioned substation equipment typically sells at 30 to 60 percent of new, but moving and recommissioning a large transformer can cost hundreds of thousands of dollars, so compare delivered and installed totals.
