Major Drivers of Long-Term Distribution Transformer Demand

Summary

This report by NREL, supported by the U.S. Department of Energy, analyzes the major drivers of long-term demand for distribution transformers in the United States, addressing an unprecedented supply-demand imbalance with lead times up to 2 years and price increases of 4–9 times. Initial NREL estimates indicate current stock of 60-80 million transformers, with projections showing a 160%-260% increase in required capacity by 2050 due to electrification. Significant demand also stems from EV charging infrastructure, requiring 125 GW for private charging by 2030 and an additional 51 GW for public charging. Furthermore, up to 2 TW of step-up transformer capacity will be needed for renewable energy integration by 2050, alongside routine replacements expected for 60-80% of service transformers by the same year and increased resilience investments against extreme weather events.
