The U.S. Department of Energy (DOE) has released a report in collaboration with the National Renewable Energy Laboratory (NREL), examining the growing demand for distribution transformers within the nation’s electrical grid. These transformers are crucial for stepping down high-voltage electricity to levels safe for consumer use across residential, commercial, and industrial sectors.

Key drivers of this demand include transformer replacements due to failure, the aging infrastructure nearing the end of its operational life, and the increasing energy needs of new customers. Emerging sectors such as data centers, electric vehicles (EVs), charging stations, and renewable energy are also contributing significantly to the need for these essential grid components.

The report reveals that approximately 55% of distribution transformers are over 33 years old, raising concerns about reliability as demand intensifies. Additionally, the study highlights a growing interest in “step-up” transformers, which share similar characteristics with distribution transformers and play a critical role in integrating renewable energy into the grid.

Michael Pesin, Deputy Assistant Secretary for Grid Systems and Components, noted, “This report will help us understand the differences in transformers used by power companies and how they will need to function to advance the grid.”

As electricity consumption rises, the findings emphasize the urgency of upgrading and modernizing transformer infrastructure to ensure a reliable and resilient power grid.
