Electric Substation Information

The Council has exclusive jurisdiction to approve electric substation facilities. (For details see C.G.S. § 16-50i (a) (4))

Substations in Connecticut are owned and operated by two publicly-traded transmission and distribution companies, United Illuminating and Connecticut Light & Power Company, as well as the municipal utilities which are associated with the Municipal Electric Energy Cooperative.

To assist the public in its understanding the purpose and operational nature of electric substation facilities, the Council has prepared this page of hyperlinks to various sources of information. Please note that this page is designed only to provide helpful links, and the Council assumes no responsibility for the contents or accuracy of the information found therein.
