Energy Grid’s Supply Chain Woes Targeted in Efficiency Proposal

The Energy Department proposed Wednesday new efficiency standards for distribution transformers, a move to expand innovation for power grid equipment coming under supply chain stress.

The department’s standard, if finalized, would require all transformers to use amorphous steel cores, a more energy-efficient technology than traditional, grain-oriented electrical steel. Officials want the new rule to take effect by 2027.

The DOE is also finalizing implementation guidance for $20 million in rebates that encourage the upgrading of distribution transformers and electric equipment with more efficient models. The department is focused on expanding US production of amorphous steel used in advanced transformers, it ...
