The annual Lawrence Berkeley National Laboratory queue report, released July 7, is the closest thing the US grid has to a state-of-the-pipeline dataset. The 2026 edition, covering data through year-end 2025, is the first in a decade to show the queue shrinking. The composition shift underneath that headline is the story.
The totals. Roughly 8,200 active projects were seeking interconnection at the end of 2025, representing 1,312 GW of generation plus 749 GW of storage. Total active queue volume fell about 10% year over year, driven by high withdrawal rates and slower new-request pace. It is the first meaningful contraction in the modern queue dataset, and it lands after three consecutive years of exponential growth.
The rebalance. Fuel-type shifts are where the report earns its keep:
- Natural gas: 253 GW active, up 86% year over year.
- Solar: 773 GW active, down 19%.
- Storage: 749 GW active, down 16%.
- Wind: 220 GW active, down 19%.
Every renewable class contracted at double digits while gas nearly doubled. That is not a marginal drift. It is the queue repricing around firm-capacity demand from data centers, load-growth forecasts, and the FERC co-located-load reforms that took effect this spring.
Why the withdrawal spike matters. LBNL’s Joseph Rand attributes part of the contraction to FERC Order 2023 compliance beginning to bite: higher milestone payments, expanded site-control requirements, and automatic withdrawal penalties are pushing speculative projects out of queues faster than in prior cycles. “Incremental improvements are taking shape,” Rand said, while cautioning that “it is still too early to see major impacts.” The pipeline is getting cleaner, not necessarily faster.
What this reprices. Three practical reads for anyone tracking the physical buildout:
- Gas turbine order books tighten further. A queue that suddenly holds 253 GW of active gas capacity is competing for the same OEM slots already sold out through 2028. Expect price and delivery lead-time signals from GE Vernova and Siemens Energy next earnings cycle.
- Renewable interconnection outcome, not just volume, becomes the metric to watch. If storage queue capacity contracted 16% but Q1 physical storage installs are still setting records, the survivor rate on the remaining projects is what compounds. Attrition-adjusted queue depth beats headline queue depth.
- Data-center power siting logic changes. When gas queue positions balloon and renewables shrink, hyperscalers with 24/7 firm-power targets are quietly pushed toward co-located gas plus nuclear PPAs and away from a renewables-plus-storage-only design. That trend was already visible in Meta, Amazon, and Google announcements this year. The queue data is the receipt.
Thesis read. The demand vector (data-center load, IRA-driven storage, RTO reform) is intact, but the supply mix inside the queue just tilted meaningfully toward firm generation. For US-supply-chain positioning, the rebalance is a structural signal, not a cycle noise. Watch cluster-study conversion rates in PJM and ERCOT next quarter for the leading indicator on whether the shrinking queue is actually clearing faster.
