  Transformers in 2026: Shortage, Scramble, or Self-Inflicted Crisis?

  Wood Mackenzie and POWER report that U.S. transformer supply remains structurally out of balance, with multi-year deficits in large power and generator step-up units even as manufacturers commit major North American investments.

  • Main findings and actions:Wood Mackenzie estimates a 30% shortfall for power transformers and 10% for distribution units in 2025, with demand increases since 2019 of 119% for power transformers and 274% for GSUs; lead times average 128 weeks for power transformers and 144 weeks for GSUs. Despite nearly $1.8 billion–$2.0 billion in announced North American manufacturing investments since 2023, major corporate commitments include Hitachi Energy (over $1 billion continental, CA$270 million Varennes expansion, $457 million South Boston, VA project due by 2028, $106 million Alamo, TN expansion), Siemens Energy ($150 million Charlotte plant, production targeted early 2027), Eaton ($340 million South Carolina facility targeting 2027), Prolec GE (more than $300 million), Virginia Transformer Corp. ($40 million), ERMCO (>$70 million), and Central Moloney ($50 million). Unit prices have also climbed: power transformers +77%, GSUs +45%, some distribution up to 95%.

  • Background, policy, and procurement details: Federal trade measures (copper tariffs up to 50%, expanded Section 232 steel/aluminum duties) and the budget package nicknamed “One Big Beautiful Bill” (phasing down some renewables credits and tightening FEOC rules) have raised input costs and domestic‑content constraints; federal/state incentives and site support are driving reshoring to Virginia, the Carolinas, Tennessee, and elsewhere. Counterpoints include broker Patrick Tarver of Bolt Electrical LLC, who argues “There is not a shortage” and attributes delays to utility/EPC procurement practices (qualification lists, vendor rules) rather than factory capacity; Tarver says he can deliver standard substation transformers in 12 to 14 months and typically charges 12%–15% over factory cost.

  Some of the Wisconsinites working for environmental change in 2025 and beyond

  WUWM revisits several Wisconsinites working for environmental change in 2025.

  • Main focus: Profiles individuals and local efforts addressing climate, public health and land use — including Jariel Ramos (youth climate organizing and political ambition), Bazile Minogiizhigaabo Panek (Integrating Indigenous knowledge into natural resources management), David DeVooght (relocating buildings displaced by a Port Washington data center development), Lee Donahue (leading a Town of Campbell effort to build a municipal well), and Paul Florsheim (challenging shoreline access restrictions in Shorewood). Key factual items: $50 million municipal well project in the Town of Campbell to tap a deep uncontaminated aquifer; the Wisconsin DNR provided bottled water to more than 1,700 households for PFAS contamination; a cited fine of $313 in Shorewood; movers have relocated two barns from the Port Washington site and moved a pole barn about six miles.
  • Background and project details: The Town of Campbell response followed state testing showing 97.3% of nearly 600 wells had PFAS; the municipal well project is described as a concrete remediation investment (cost $50 million) to secure PFAS-free water. The Shorewood case is pending a municipal judge decision expected early 2026. Vantage is named as the data center developer linked to the Port Washington site where structures are being relocated.

  Data centers revive polluting ‘peaker’ plants across U.S.

  NRG Energy withdrew a planned retirement notice for the Fisk oil-fired peaker units as surging electricity demand from AI data centers in PJM territory made peaker plants economically viable.

  • Main action: NRG Energy withdrew the retirement notice for Fisk’s eight oil-fired peaking units (December 2025) after AI data center demand drove prices in PJM higher; PJM said the market shows electricity demand outstripping supply and that existing generation is needed while new generation comes online. Key facts: Fisk = eight peaking units on former coal station site; EPA estimated sulfur dioxide 2 to 25 tons/year from the site; PJM prices to suppliers soared by more than 800% this summer.
  • Background & other details: Reuters analysis found about 60% of oil, gas and coal plants slated for retirement in PJM postponed or cancelled retirements this year; 23 plants were scheduled to retire starting in 2025 in PJM territory, and since January 13 retirements were delayed or cancelled (of those, 11 were peakers). The U.S. Government Accountability Office notes peakers supply about 3% of the country’s power but have capacity to produce 19%, and federal actors (DOE/Administration) have signaled interest in tapping spare capacity.
