NY-Sun incentives from NYSERDA still drive a large share of New York solar economics, but the blocks decline by region. Installers serving Con Edison territory, Long Island, and Upstate face different incentive levels and different permitting realities. This guide covers how to keep NY-Sun documentation aligned with plan sets and interconnection in 2026.
NY-Sun Regions and Why Timing Matters
NY-Sun capacity blocks are tracked separately for Con Edison, Long Island, and Upstate regions. When a block closes, the incentive drops. Sales proposals and design packages should reflect the current block so customers and financiers are not surprised. Athol Energy builds current NY-Sun assumptions into sales proposals and design documentation.
NYC DOB vs Upstate AHJs
New York City filings go through the Department of Buildings and must satisfy FDNY rooftop access rules, including clear path requirements that reshape array layouts. Upstate markets such as Albany and many towns use the Uniform Code, and some qualify for the state’s unified solar permit process. Long Island towns and villages each run their own building departments under coastal wind conditions.
SIR Interconnection Across New York Utilities
Interconnection follows the New York Standardized Interconnection Requirements (SIR) for Con Edison, PSEG Long Island, National Grid NY, NYSEG, RG&E, Central Hudson, and Orange & Rockland. Larger commercial projects may enter CESIR study. Our interconnection and permit design teams keep SIR applications synchronized with AHJ plan sets. See New York solar design services for statewide coverage.
Bottom Line for Installers
Design to the AHJ that will actually review the project, lock NY-Sun block assumptions early, and submit SIR interconnection in parallel. That combination keeps New York projects moving.
