Vermont Electric Power Company proposes to upgrade the Newport substation. The upgrade is needed because a recent conditions assessment revealed deficiencies within the substation. In addition to the transmission system upgrade, Vermont Electric Cooperative (VEC) proposes to rebuild the Newport distribution switch station within the same fence line as VELCO's Newport substation. The proposed project will improve the reliability of electric facilities serving northeast Vermont.
Needs & Benefits
The VELCO Newport substation is connected to VELCO’s electric transmission network in northeast Vermont. The northeast Vermont electric distribution systems are fed from VELCO’s transmission network serving VEC customer members.
Originally built by Citizens Utilities in 1992, the VELCO Newport substation has not undergone major improvements or modifications since that time. VELCO conducted a condition assessment of the station and has identified the need to replace outdated equipment. For example, some critical components are at the end of their useful life, and certain components are no longer supported by the manufacturer.
The VEC distribution switch station was built circa 1920s-1930s. The station has inadequate working clearances and does not have the redundant sources necessary to support maintenance activities and respond to contingencies.
