Why deregulated energy?

The purpose of deregulated energy is to save customers money on their monthly energy bills. Connecticut legislation opened the energy market to retail suppliers from across the country that offer customers great rates and plan options that fit almost any budget.

Choose Energy makes it easy for Connecticut energy customers to compare deregulated plans from retail suppliers. These suppliers offer competitive prices and incentives that the local utility usually can’t beat. To find a deregulated energy rate in your area, visit the Choose Energy marketplace!
