Projects in U.S. grid interconnection queues show particularly low completion rates for solar and battery storage compared to other energy types. While 78% of all energy projects proposed between 2000–2018 withdrew, specific withdrawal percentages for solar and battery storage as a combined group are not explicitly provided in the results. However, completion rates (the inverse of withdrawals) highlight the disparity:
- Solar: Only 14% of proposed projects between 2000–2018 became operational
- Battery storage: Just 11% of proposed projects were completed
This implies withdrawal rates of ~86% for solar and ~89% for battery storage individually during that period. Recent data (2023) indicates solar, wind, and battery projects dominate current queues (95%+ of new requests), but updated withdrawal percentages for these specific technologies post-2018 are not detailed in the sources.
The studies emphasize that interconnection delays and costs disproportionately affect renewables and storage, with withdrawal rates remaining persistently high across all technologies. For newer projects (post-2018), 70% of all projects withdraw at some stage, but solar/battery-specific withdrawal rates within this cohort are not broken out.
Limitation: The data conflates withdrawal rates for solar and battery storage with broader queues. Exact combined withdrawal percentages for solar + battery projects are not directly reported.
