Power Transformers Market News

  • August 2023: As part of President Biden’s Investing in America agenda, the United States Department of Energy (DOE) announced USD 20 million to support the installation of energy-efficient distribution transformers and comprehensive product systems that utilize equipment with electric motors, such as pumps, air compressors, and fans. 
  • June 2023: The Department of Energy (DOE) suggested new energy-efficiency standards for three categories of distribution transformers. Almost all transformers delivered under the new standard would utilize amorphous steel cores, which DOE stated are more energy efficient than those produced by traditional, grain-oriented electrical steel. If adopted within DOE’s proposed timeframe, the new rule would take effect from 2027. To convey products in adherence with the amended standards, the DOE estimated the industry would incur total conversion costs of about USD 270.6 million for liquid-immersed distribution transformers, around USD 69.4 million for low-voltage dry-type distribution transformers, and about USD 3.1 million for medium-voltage dry type distribution transformers.
