U.S. Transmission Bill Could Speed Renewable Grid Builds

A U.S. federal bill targeting transmission infrastructure reforms may cut renewable grid project timelines significantly, though environmental safeguards and fossil fuel incentives create friction.

The Bipartisan American Affordability and Jobs Act of 2026 (BAAJA) proposes transmission reforms that NRDC analysis suggests could reduce the time to build major new power lines from 10+ years to 5-6 years. This potential acceleration would free up 100+ gigawatts of transmission capacity—enough to power 75 million homes—by requiring the Federal Energy Regulatory Commission (FERC) to set deployment timelines for cost-effective transmission technologies. Recent regional examples show the urgency: PJM halted new grid connections in 2022 due to a 300+ gigawatt backlog (95% renewables and storage), and the Southwest Power Pool approved a 20-year transmission planning approach in March 2026.

The bill’s mechanism hinges on mandating standardized transmission planning processes across grid regions within two years of enactment. However, NRDC analysis also flags significant friction: BAAJA’s 'project certainty' language could disproportionately benefit fossil fuel, mining, and industrial projects over clean energy, while weakening environmental laws including the Clean Water Act and Endangered Species Act. Additionally, Trump-era policies under this framework might double U.S. power sector carbon emissions and raise consumer utility bills by $30 billion annually by 2035.

This shift moves renewable energy access closer to affordability by accelerating grid integration, but the environmental tradeoffs and fossil fuel bias mean clean energy gains remain gated. What matters next is whether NRDC’s planned improvements to this assessment—before a floor vote—address the bill’s structural bias toward fossil fuels and environmental protections. The November 6, 2026 publication date confirms this assessment is still evolving, not final.
