Washington, D.C. —The U.S. electric transmission system is beginning to make progress, but planning and development efforts remain uneven and, in many regions, too slow to keep pace with rapidly accelerating electricity demand. The 2025 Transmission Planning and Development Report Card, produced by Americans for a Clean Energy Grid and Grid Strategies, evaluates transmission planning and development across 10 U.S. regions. The report finds that recent reforms — particularly those tied to FERC Order No. 1920 — are beginning to improve outcomes in several regions, but rising demand from data centers, advanced manufacturing, and economy-wide electrification is compressing planning timelines and raising the cost of delay. Top-performing regions like California, the Midwest, and the Plains demonstrate the benefits of sustained, long-term transmission planning, while regions without organized regional or interregional frameworks continue to lag despite growing transmission needs. Interregional transmission planning remains one of the weakest elements of the national planning landscape.
