The majority of Connecticut is serviced by the utility Eversource (formerly Connecticut Light & Power (CL&P)). Customers who do not shop for competitive rates pay a default rate known as the General Service Rate (GSC).

Connecticut Energy Rates

The GSC rate can be found on your CL&P bill under “Supplier Service Detail”. When you choose another electric supplier with a lower rate, you will still get the same bill from Eversource (CL&P), with the lower electricity rate replacing the default rate. The electric bill from Eversource (CL&P) will state your electric supplier underneath “Supplier Service Detail” followed by your KWh consumption and rate.

Connecticut might be the third smallest US state by land area, but the energy choices that Connecticuters have are not. Several large and small energy retailers compete for the attention of Connecticut residents with competitive energy rates. There are alternative energy choices, too – go renewable, for example with a solar panel. One thing is for certain, if your current plan is the default, shop around!
