The report focuses at the number of U.S. distribution transformer units, the number and capacity of the assets, the units’ current age profile, and demand for distribution transformers.

The U.S. Department of Energy’s (DOE) Office of Electricity (OE) has released a report for distribution transformers in the electrical power grid.

The report, prepared by researchers at the National Renewable Energy Laboratory (NREL) for OE, focuses at the number of U.S. distribution transformer units, the number and capacity of the assets, the units’ current age profile, and demand for distribution transformers, which may increase in the future.

Researchers found three factors driving demand for distribution transformers:

• how many fail and require replacement,
• how many reach their end-of-life, and
• how the increasing number of new customers are driving demand on an annual basis.

The study also highlighted the major drivers of demand including data centers, electric vehicles and charging stations, and renewable energy generation requiring step up transformers with similar characteristics to distribution transformers. There are different types of transformers, which are either mounted on the power pole or on the ground.
