About Energy Choice in Bridgeport
Bridgeport is the largest city in Connecticut and, unlike Hartford or Waterbury, it sits inside the United Illuminating (UI) service territory rather than Eversource's. UI covers seventeen towns along the southwestern Connecticut shoreline including Bridgeport, Fairfield, Stratford and Trumbull — roughly 340,000 customers total. That matters when you shop, because UI's Standard Service supply rate is set on its own PURA-approved schedule and typically differs from Eversource's by a fraction of a cent per kWh in either direction.
The mechanics of Connecticut Energy Choice work the same on a UI bill as an Eversource bill: PURA licenses the competitive supplier, UI keeps operating the poles, wires and meters, and only the 'Generation Services Charge' line on the bill changes. What differs is the plan menu — some suppliers file offers exclusively for UI ZIPs, others exclusively for Eversource ZIPs, and a Bridgeport shopper will not see the full statewide catalog.
Natural gas delivery in most of Bridgeport is handled by Southern Connecticut Gas (SCG), another Avangrid subsidiary. SCG runs the gas-supply Choice program separately, and gas-supply switches never touch the electric account. Because Bridgeport's housing stock includes a lot of older multi-family buildings with mixed heat sources, it's worth checking your actual therm usage before pursuing a gas contract on top of an electric one.

Frequently Asked Questions
Who is Bridgeport's electric utility?
United Illuminating (UI), an Avangrid company, is the electric distribution utility for Bridgeport and the rest of southwestern Connecticut's coastal region. UI — not Eversource — owns the wires and answers outage calls in every Bridgeport neighborhood.
Is the Standard Service rate the same for UI Bridgeport customers and Eversource customers?
No. UI and Eversource run separate Standard Service procurements approved by PURA, so the default supply rate on a Bridgeport UI bill is set independently of the Eversource number Hartford or Waterbury customers see, even though both reset on the same January/July schedule.
Will switching electric suppliers in Bridgeport disrupt my service?
No. UI continues to deliver the electricity, read the meter and respond to outages exactly as before. Only the 'Generation Services Charge' line on your UI bill changes to reflect the new supplier's contracted rate.
Who delivers natural gas in Bridgeport?
Southern Connecticut Gas (SCG) — also an Avangrid company — is the gas distribution utility for most Bridgeport addresses. SCG handles the meter, the mains and gas emergencies regardless of who supplies the therms.

Report electric outages and downed lines to United Illuminating at 1-800-722-5584. For gas leaks and gas emergencies in Bridgeport, call Southern Connecticut Gas at 1-800-513-8898.
