DOE Proposes Distribution Transformer Efficiency Standards Amid Steel Supply Concerns

DOE's January 2023 proposed rule raises minimum efficiency standards for certain distribution transformers, potentially requiring greater use of amorphous steel. Industry and Congressional stakeholders cite supply-chain delays (22-33 months vs. prior 2-4 months) and over-reliance on foreign electrical steel producers, prompting calls to invoke the Defense Production Act and legislative efforts to delay the rule.
