Electric Cooperatives Grapple with Persistent Supply Chain Strains

Electric cooperatives across the U.S. continue to face significant supply chain challenges more than 4 years after initial disruptions intensified. Surging electricity demand—driven largely by data centers, AI, electrification, and population and economic growth—has collided with limited manufacturing capacity, aging infrastructure, and raw material constraints, creating backlogs that threaten timely service and grid reliability.

Distribution transformers remain the most critical shortage, with lead times stretching from a pre-2021 average of ~70 days to 300+ days (and up to 1 to 2 years in peak periods). Power and substation transformers face even longer delays, often 2 to 3+ years. Other hard-to-source items include conductors (wire/cable), utility poles, crossarms, reclosers, switchgear, and fiberglass components. Prices for key equipment have roughly doubled or tripled, while storm recovery efforts further deplete strategic inventories.

These pressures stem from manufacturing capacity limits (U.S. production historically meets only a fraction of demand for some items), shortages of electrical steel, copper, and other materials, and lingering logistics issues. Regulatory factors add friction: past efficiency standards for transformers created uncertainty around core materials and timelines, while steel/aluminum tariffs complicate sourcing. Lengthy permitting processes slow infrastructure projects, sustaining demand on strained supplies.

Cooperatives, through NRECA and regional efforts, are advocating for domestic manufacturing incentives, permitting reform, and better resource pooling to ease the crunch. New factory expansions offer hope, but challenges are expected to persist into 2027 as load growth accelerates.
