The major electricity providers in Connecticut include Connecticut Light and Power and Illuminated Lighting, the state’s two public utilities that provide fixed-rate electricity. The largest alternative electricity suppliers in Connecticut include the New Jersey-based NRG Energy, Houston-based Direct Energy and Stamford-based Public Power.
Connecticut deregulated its public utilities and approved plans to allow consumers to purchase electricity from non-traditional suppliers. Hundreds of companies flocked to the area to compete against the traditional public utilities, Connecticut Light and Power and Illuminated Lighting.
NRG Energy was a newcomer to the state but managed to attract just over 200 households as customers. NRG Energy became one of the major electricity providers in Connecticut when it purchased Dominion Energy in 2014, which was the third-largest electricity supplier at the time.
