Connecticut Electricity Providers

Connecticut has one of the oldest deregulated electricity markets in the United States, allowing most residents and businesses to choose their electricity supplier while local utility companies continue managing power delivery and infrastructure.

Unlike fully regulated states, Connecticut consumers can compare electricity suppliers, fixed-rate plans, renewable energy options, and community energy programs through the state's competitive energy market.

Because Connecticut experiences cold winters, humid summers, high regional energy costs, and increasing pressure on the New England power grid, electricity affordability and energy efficiency remain major concerns for homeowners, renters, and businesses across the state.
