US Energy Department Offers $237 Million to Build Domestic Supply Chains for Grid Transformers

The US Department of Energy on October 30 opened a $237 million funding opportunity aimed at building domestic supply chains for the transformers and other components that utilities need to connect new load and replace ageing equipment. The programme, called Grid Supply Chain Alternatives to Lead Energy Dominance (Grid SCALED), is the first funding call under DOE’s new Grid Supply Chain Program and is run by the department’s Office of Electricity.

The money is split into two areas. Up to $50 million will go to projects that increase the refurbishment and reuse of existing grid equipment and materials, and up to $187 million to projects that expand the use of alternative materials and subcomponents made and sourced in the United States. Concept papers are due on November 20, 2026, and full applications on February 8, 2027, according to the department’s funding notice.

Refurbishment and substitute materials, not new factories

The design of the first call is notable for what it leaves out. Rather than financing new transformer plants, Grid SCALED targets two ways of stretching the existing equipment base and the domestic materials chain: putting used equipment back into service, and swapping in US-sourced inputs where manufacturers currently depend on imports. DOE said the wider Grid Supply Chain Program is authorised to provide up to $375 million for domestic supply chains covering distribution and power transformers, grid components and materials, which leaves roughly $138 million for later rounds. Further funding announcements are expected in 2027, including for next-generation technologies such as solid-state transformers and for common equipment configurations.

The department estimates the first round could generate about $125 million a year in utility savings and keep about $50 million a year in the US economy that would otherwise go to foreign suppliers. Those are DOE projections and have not been independently assessed.

Applications run in two stages: DOE requires a concept paper before it will accept a full proposal, which lets the department screen projects early. With less than three weeks between the announcement and the November 20 cut-off, the timetable favours teams that already have refurbishment or materials projects in development. The department has not published individual award sizes or the number of awards it expects to make, so it is not yet clear whether the money will be spread across many small projects or concentrated in a few larger ones.

“America should never have to rely on foreign suppliers to keep the lights on,” said Katie Jereza, DOE’s assistant secretary for electricity. Energy Secretary Chris Wright said the programme would help “reduce reliance on foreign suppliers and deliver affordable, reliable, electricity.”

A long-running equipment squeeze

Transformers have become one of the tightest links in the US power build-out as utilities race to serve data centres, new factories and electrification. A preliminary analysis by the National Renewable Energy Laboratory, published on DOE’s transformer research pages, estimates that the country has 60 to 80 million distribution transformers in service with more than 3 terawatts of installed capacity, and projects that total stock capacity could grow by 160% to 260% between 2021 and 2050.

Demand for that equipment is showing up across the industry. Large utilities have been lifting capital plans to meet data centre load — AEP raised its five-year plan to $100 billion this week — while GE Vernova has agreed to buy high-voltage equipment maker Trench Group for $9 billion. DOE’s financing arm has also been active on the generation side, committing $10.1 billion in loans to Constellation and Alliant for about 3.7 GW of new and upgraded capacity.

The cost pressure is reaching households too. J.D. Power data cited by T&D World put the average US monthly residential electricity bill at $188 in the third quarter of 2026, up 5.6% from $178 a year earlier. The trade publication noted that reliance on foreign suppliers of bulk-power equipment has been flagged by the administration as a supply-chain vulnerability.
