Generator Installation in New York, NY
Con Edison customers averaged 28 minutes without power in 2024 — far below the US average of 11 hours, among the most reliable of the 58 metros we track. Sustained outages are rarer here than in most of the country, but storm and equipment-driven interruptions still happen — and homeowners with medical equipment, a home office, a well pump or a sump pump often want backup regardless of the average. Below are generator installers serving New York and the rest of New York County, ranked by reputation.

How much does generator installation cost in New York?
In New York, a whole-house standby generator (18–26 kW) typically runs $10,000–$20,000 installed, including the transfer switch, gas connection, pad and permits. A smaller essentials-only unit (10–14 kW) runs $8,000–$13,000. A portable generator with an interlock kit is the budget option at $800–$2,000.
Do I need a permit for a generator in New York, NY?
Almost everywhere, yes. A standby generator needs an electrical permit and usually a gas/plumbing permit, and most states require the work be done by a licensed contractor. A reputable New York installer pulls the permit for you — treat anyone who offers to skip it as a red flag, since unpermitted work surfaces at resale and can void insurance claims.
Who installs generators in New York?
Licensed electricians and specialized generator dealers handle installation. A standby generator also needs a gas connection, so many jobs involve both an electrician and a plumbing contractor — dealers coordinate both.
Why are outages common around New York?
Con Edison customers averaged 28 minutes without power in 2024 — far below the US average of 11 hours, among the most reliable of the 58 metros we track. Sustained outages are rarer here than in most of the country, but storm and equipment-driven interruptions still happen — and homeowners with medical equipment, a home office, a well pump or a sump pump often want backup regardless of the average.
