About Eversource Energy

Eversource Energy, formerly known as Connecticut Light and Power, is one of the top utility companies in Connecticut, serving more than 1.2 million electric customers and 222,000 natural gas customers throughout the state. As the largest utility service in greater New England, Eversource provides safe and reliable energy to residents and business owners.

Eversource is proud to maintain its role as one of the nation’s greenest energy companies through initiatives like climate leadership, clean energy and accountability. Eversource works with the Connecticut community to educate energy users about conservation efforts and efficient product options.

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!
