PSEG Long Island serves all of Long Island — Nassau and Suffolk counties — at rates of $0.22–$0.28/kWh, among the highest in New York. Long Island is one of the strongest solar markets in the Northeast, driven by high rates, large suburban roof planes, and the full NY incentive stack.
Key facts for PSEG Long Island solar customers:
- PSEG LI offers net metering — excess production earns retail-rate bill credits
- PSEG LI administers its own NY-Sun Megawatt Block blocks through NYSERDA
- Interconnection applications submitted by your installer through PSEG LI's portal
- Typical interconnection timeline: 8–16 weeks for residential systems
- Nassau County: permits at the town/village level
- Suffolk County: permits at the town level (Huntington, Babylon, Islip, Brookhaven, etc.)
Long Island's solar installer market is competitive — which keeps prices lower than upstate and drives better customer outcomes. With PSEG LI's high rates, federal 30% ITC, NY 25% state credit, and NY-Sun Megawatt Block, Long Island solar paybacks of 5–7 years are common for well-sited homes.
