About Energy Choice in New Haven
United Illuminating was founded in New Haven in 1899, and the city is still the operational heart of the UI service territory. For the customer, that has one practical effect: the same wires company that ran the trolley system a century ago still owns the meters, transformers and outage response in every New Haven neighborhood — East Rock, Westville, Fair Haven, downtown or Wooster Square — and that does not change when a supply contract does.
New Haven's competitive supply market moves in lockstep with the January and July PURA resets that set UI's default 'Standard Service' rate. Households that only compare offers around those two windows tend to save the most, because suppliers publish their sharpest 12- and 24-month fixed rates in the weeks before a scheduled increase. Between resets, most of the plans on the state's rate board sit within a narrow band of each other and of the Standard Service number itself.
One New Haven wrinkle worth flagging: a large share of the housing stock is multi-family with tenant-paid electricity, and Connecticut law requires that a landlord cannot enroll a tenant's meter in a competitive supply contract. If you rent in New Haven, the account has to be in your name for you to switch — and the switch travels with the account, not the address, if you move within UI territory.

Frequently Asked Questions
Who provides electricity in New Haven, CT?
United Illuminating (UI) is the electric distribution utility for New Haven and the surrounding UI service area. UI delivers the electricity and owns every pole, wire and meter in the city no matter which licensed supplier a customer signs with.
How does UI's Standard Service rate work?
It's the default supply rate PURA procures on behalf of New Haven customers who haven't chosen a competitive supplier. UI passes it through at cost, and PURA resets it every January 1 and July 1 through a wholesale procurement process.
Can I really save money against UI's Standard Service?
Sometimes. Fixed-rate offers filed by licensed suppliers on the state's rate board often beat the Standard Service number in the weeks before a scheduled reset and lag it in the weeks after. Compare the exact ¢/kWh — and the contract length — against the current UI Standard Service rate for your billing period.
Who is the gas utility for New Haven?
Southern Connecticut Gas (SCG) delivers natural gas to New Haven addresses. SCG operates its own Choice program for gas supply, independent of UI's electric Choice program.
Who do I call for a power outage in New Haven?
Report New Haven electric outages to United Illuminating at 1-800-722-5584. That number is UI's responsibility as the distribution utility and does not change after switching electric suppliers.
