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).

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.
