Western US Transmission Bottleneck Forces 12,600-Mile Grid Expansion by 2035
The West-Wide Transmission Study mandates over 12,600 miles of new high-voltage transmission lines by 2035 to handle clean energy integration and load growth. This represents a fundamental infrastructure constraint forcing massive capital deployment, as current grid capacity cannot support the renewable energy transition at required scale.
Transmission infrastructure is now the critical bottleneck determining renewable deployment speed and regional energy transition competitiveness. Grid expansion timelines will dictate which regions capture clean energy investment flows.
