PJM generator interconnection: application-to-commercial-operation timeline (vs <2 yr in 2008); a generation statistic, not a large-load service timeline

>8 yrobserved

Value kindobserved — Reported measurements, counts, and specifications keep the precision and scope stated by their source; an exact specification is not treated as a range.
ScopeRMI's PJM figure is the mean time from application to commercial operation for generation projects that came online in 2025. LBNL's Queued Up 2026 edition uses a different statistic and regional basis: a 61-month median from request to COD for projects built in 2025 (in regions with data), against 22 months in 2008. Neither measures how long a data center waits for load service.
