The project in Cumberland involves the construction of a new 345 kV transmission line, Section 3020, that will run southeasterly in the existing corridor from the North Yarmouth town line, traversing the Cumberland/Yarmouth municipal boundary, to the new Raven Farm Substation that will be constructed on Greely Road.

The Raven Farm Substation site is located at an existing electrical node in CMP’s bulk power system. More specifically, the substation site is located within an existing 450‐foot wide CMP transmission line corridor situated northeast of Greely Road and northwest of Middle Road in Cumberland. This corridor contains two 115 kV lines and one 345 kV line. There are also four 34.5 kV lines converging to the north of this area as well as CMP’s Elm Street Substation located to the north in Yarmouth.

The Raven Farm Substation will upgrade the reliability of the CMP system by providing additional 345 kV switching capability at this site. This will be accomplished by connecting the new substation with the proposed 345 kV transmission line running from the Surowiec Substation in Pownal (Section 3020, pending town approval) and the existing 345 kV line (Section 3040) that runs to CMP’s South Gorham Substation.

As described in the PUC Certificate of Public Convenience and Necessity (CPCN) for the MPRP, the two existing 115 kV lines will not be connected to the 345 kV system at the Raven Farm Substation with an autotransformer at this time. However, the two 115 kV lines will be constructed on two A‐frame dead end supports within the graded substation yard to accommodate future 345 kV to 115 kV transformation.
