How Deregulated Electricity Works in Connecticut
Connecticut deregulated its electricity market in 1998. The system operates with three components: power companies generate electricity (generation), utilities maintain high-voltage lines (transmission), and your local utility (Connecticut Light & Power Co, United Illuminating Co) delivers electricity to your home (distribution).
You can choose your electricity supplier from 14 competing providers. If you don't select a supplier, you automatically receive default service through your utility at a regulated rate.
