Middlebury Study Area

 

VELCO and CVPS have identified reliability deficiencies in the Middlebury Study Area. VELCO system issues include the impacts of loss of the transformers at New Haven and Middlebury. The CVPS subsystem deficiency concerns contingencies on the 46 kV radial line from Salisbury to Weybridge.

NTA screening was completed by CVPS in July 2007 and resulted in the exclusion of NTAs for this project. The NTA screening and exclusion were presented to the VSPC Transmission Subcommittee at its December 10, 2007, meeting, resulting in an agreement that CVPS will update the data used in its analysis and present the update to the Subcommittee. The NTA screening and recommendation regarding exclusion of  the Middlebury deficiencies from further NTA consideration will be presented to the full VSPC. Since this is the first project to move forward through the VSPC review process, the Technical Coordinating Subcommittee plans to utilize VSPC feedback from this experience to develop recommendations for the process of review for future projects.

The map on the left shows roughly the area potentially affected by this reliability deficiency.
