The proposed MPRP construction in the Town of Wales will be located
within the existing CMP transmission corridor and includes both
transmission line removal and the construction of a new 345 kV
transmission line. The new 345 kV transmission line will be constructed
on H-frame structures typically 75 feet in height. The existing 34.5
kV transmission line will be decommissioned and removed. The existing
115 kV transmission line will be removed and rebuilt on monopole
structures typically 75 feet in height.
In addition to the proposed transmission line improvements, the existing Wales Corner Substation will be decommissioned. The existing Wales Corner Substation comprises approximately 0.10 acres, and is located within CMP’s existing corridor on the west side of Route 132. The substation, including all components and concrete foundations, will be entirely removed from the corridor and the land will be allowed to revegetate.
