Bottom line

Fast-growing large-load interest and an active reform push, but high costs, CLCPA clean-energy constraints, and a queue process still being redesigned create timing uncertainty.

Generation queue notes
Transitioning from class-year process to a Class Year Queue Window (cluster) concept. New cluster process targets ~50% faster path to construction for projects entering Q3 2024 onward. Methodology changes under review aim to reduce unnecessary upgrade costs.
Large-load posture rationale
Large-load queue grew from 1 GW (6 projects) in 2022 to ~11.9 GW (48 projects) by early 2026, much data-center-related. Gov. Hochul launched a PSC proceeding (Energize NY) to make data centers pay their fair share. NYISO evaluating large-load-specific interconnection reforms.

Rationale
Fast-growing large-load interest and an active reform push, but high costs, CLCPA clean-energy constraints, and a queue process still being redesigned create timing uncertainty.
What's working
  • New cluster process targets ~50% faster path to construction.
  • Active state-level effort to clarify cost allocation and speed responsible development.
What's working against
  • High power costs and CLCPA clean-energy mandates constrain generation options.
  • Queue redesign and possible legislative moratorium create regulatory uncertainty.
One thing to watch
The December 2026 NYISO Board approval / FERC filing and whether New York leans toward a data-center moratorium or a structured framework.
Analyst note
New York wants data-center investment but on its own terms: pay your way, fit the clean-energy mandate. The 12x growth in large-load queue since 2022 shows the demand is real. For now it is a watch-and-position market while the rules settle through late 2026.
