The Topic

Changes to US federal permitting processes are delaying or putting at risk a large pipeline of wind, solar, and battery storage projects. Wood Mackenzie estimates that 92 GW of early-stage projects, representing more than $121 billion in potential investment, faces heightened scrutiny, while developer surveys report longer timelines and higher costs. The disruption comes as electricity demand is expected to rise, particularly from data centers and manufacturing, and as clean energy groups challenge the new review procedures in court.

Summary
- Wood Mackenzie identifies 92 GW of early-stage wind, solar, and storage projects facing heightened federal scrutiny.
- More than $121 billion in potential investment is exposed, while about 7 GW on federal land was already stalled or canceled in 2025.
- Wetlands, wildlife, access-road approvals, and Army Corps reviews are major constraints for projects on or near private land.
- Onshore wind projects face additional delays from Department of Defense airspace and military-radar reviews.
- A survey of developers found delays averaging more than six months and widespread increases in project costs.
- Renewable energy groups are using litigation to challenge Interior and Pentagon review policies, leaving some projects subject to injunctions and appeals.
- The permitting uncertainty coincides with projected growth in electricity demand from data centers, manufacturing, and broader electrification.
History
The story now adds a stronger legal and procedural dimension: renewable groups are actively challenging the federal review changes in court, while the current framing drops the earlier emphasis on tariffs and foreign-entity tax-credit risks. It also sharpens the permitting bottlenecks by naming Defense airspace/military-radar review and Army Corps approvals as key constraints.
The story sharpens from broad permitting bottlenecks into a more specific picture of Trump-administration review changes actively slowing or jeopardizing projects, with quantified impacts on stalled capacity and costs. It also adds separate tariff and foreign-entity rules as new sources of risk for projects already underway.
