Washington, DC – Senator Joe Manchin (D-WV), Chairman of the U.S. Senate Power and Pure Assets Committee, led 47 bipartisan Senators in urging Division of Power (DOE) Secretary Jennifer Granholm to chorus from finalizing a DOE effectivity normal that might worsen the present scarcity of distribution transformers, that are vital grid merchandise. The proposed rule comes at a time when the provision of important grid elements stays a big problem for the electrical energy trade, and whereas the trade is struggling on account of a considerable enhance in demand, provide chain points and a talented workforce scarcity.
“We urge the Division to chorus from promulgating a closing rule that can exacerbate transformer shortages at this strategically inopportune time. Such an ordinary may come at significant value to grid reliability and nationwide safety, persevering with the clear vitality transition, and bolstering home provide chains and the workforce. As an alternative, we urge the Division to finalize a rule that doesn’t exacerbate the scarcity in distribution transformers and convene stakeholders throughout the provision chain to develop consensus-based strategy to setting new requirements,” the Senators stated partly.
The proposed rule, Power Conservation Program: Power Conservation Requirements for Distribution Transformers would require a shift from the trade normal grain oriented electrical metal (GOES) cores to amorphous metal cores, which might worsen the present provide chain scarcity as producers would want to regulate their manufacturing traces. Common lead instances to acquire distribution transformers have already elevated considerably, rising from eight to 12 weeks to as much as three years between 2020 and 2022, which has impacted grid modernization and reliability efforts.
“At the moment, the US solely has one home producer of amorphous metal. Transferring to amorphous metal cores, as proposed by DOE, would require this sole home provider to quickly scale operations from its present market share of lower than 5 % to accommodate the whole distribution transformer market,” the Senators continued. “We’re dedicated to working with you to establish quick and long-term options to the provision chain scarcity of those vital grid elements with a objective of constructing a sturdy home market and a extra environment friendly and dependable grid for many years to return.”

We write to you concerning the U.S. Division of Power’s (DOE or the Division) Proposed Rulemaking: Power Conservation Program: Power Conservation Requirements for Distribution Transformers (Proposed Rule). The provision of vital grid elements stays a big problem for the electrical energy trade that would affect nationwide safety, grid reliability and resilience, in addition to the flexibility to proceed the vital work of electrification and grid modernization.
The Proposed Rule will increase effectivity requirements on distribution transformers, vital grid merchandise, which at present are a minimum of 97.7% vitality environment friendly, at a time when the trade is struggling on account of a big enhance in demand, provide chain points, and expert workforce scarcity. These components have made it laborious for producers to satisfy present demand for distribution transformers, creating difficult lead time circumstances and issues concerning grid reliability and resiliency. Additional, the proposed rule has launched uncertainty that forestalls utilities from signing long-term contracts and producers from making funding selections.
The Proposed Rule would require all distribution transformers to shift from the trade normal grain oriented electrical metal (GOES) cores to amorphous metal cores. GOES at present accounts for greater than 95 % of the home distribution transformer market and, due to this fact, producers’ manufacturing traces are tooled for designs that use GOES. A closing rule that adopts DOE’s present proposal may meaningfully worsen the present provide chain scarcity by requiring producers to alter manufacturing traces to much less available amorphous metal.
At the moment, the US solely has one home producer of amorphous metal. Transferring to amorphous metal cores, as proposed by DOE, would require this sole home provider to quickly scale operations from its present market share of lower than 5 % to accommodate the whole distribution transformer market. Such a recalibration of the provision chain will additional delay manufacturing manufacturing timelines – at present estimated to be a minimal of 18 months to 2 years.
Between 2020 and 2022, common lead instances to acquire distribution transformers went from eight to 12 weeks to as much as three years. This multi-fold enhance is straight impacting the electrical energy trade’s grid modernization and reliability efforts, in addition to its capability to reply and get well from pure disasters, posing challenges for communities that must rebuild in addition to new improvement.
We respect the actions that this and former administrations have already taken in recognition of the challenges related to distribution transformer provide chains, together with the 2022 designation of GOES on the U.S. authorities’s record of “vital items and supplies” and the invocation in the identical 12 months of the Protection Manufacturing Act to speed up the manufacturing of “vital energy grid infrastructure like transformers.”
Nonetheless, by phasing out the first marketplace for U.S.-produced GOES, the Proposed Rule may jeopardize this progress, placing on a regular basis American households in danger. Additional, we’re involved that requiring the usage of amorphous metal for brand new distribution transformers may put the administration’s electrification targets in danger by exacerbating an current grid vulnerability.
On the similar time, we acknowledge the quite a few and infrequently underappreciated advantages of vitality effectivity and assist the general objective of lowering wasteful electrical losses in our distribution grid. We imagine essentially the most prudent plan of action is to let each GOES and amorphous metal cores coexist available in the market, as they do right now with out authorities mandates, for brand new installations as we ramp up home manufacturing and reorient provide chains.
We urge the Division to chorus from promulgating a closing rule that can exacerbate transformer shortages at this strategically inopportune time. Such an ordinary may come at significant value to grid reliability and nationwide safety, persevering with the clear vitality transition, and bolstering home provide chains and the workforce. As an alternative, we urge the Division to finalize a rule that doesn’t exacerbate the scarcity in distribution transformers and convene stakeholders throughout the provision chain to develop consensus primarily based strategy to setting new requirements.
We request a briefing together with your workplace on the trail ahead on DOE’s proposal, in addition to the right way to greatest leverage current DOE authority to bolster home provide chains and assist alleviate the present and persisting provide chain challenges going through distribution transformers. We’re dedicated to working with you to establish quick and long-term options to the provision chain scarcity of those vital grid elements with a objective of constructing a sturdy home market and a extra environment friendly and dependable grid for many years to return.
Thanks in your consideration.
