WEST RUTLAND SUBSTATION UPGRADE
PROJECT SUMMARY
Public Service Board Docket 7675

Vermont Electric Power Company (VELCO) is proposing an upgrade to our existing substation located on Pleasant Street in West Rutland, Vermont. The proposed West Rutland Substation Upgrade would install two "capacitor banks" and the associated equipment designed to control low voltage during high demand on the electric transmission system in Rutland and surrounding counties.

VELCO constructed the VELCO West Rutland substation in 1969 to support and maintain system reliability for the Vermont electric system. Around 2006, VELCO made some upgrades to the substation as part of the Northwest Vermont Reliability Project. The need to improve reliability deficiencies of the Vermont Transmission System were identified in VELCO’s 2006 Vermont Transmission System Ten-Year Long Range Plan and its 2009 Vermont Long-Range Transmission Plan. One of these deficiencies can be corrected by upgrading the West Rutland substation to reduce electrical losses by improving and maintaining the voltage profile during high demand.

The proposed project will install the following components:

• two (2) new capacitor banks
• new disconnect switches
• new buswork
• protection equipment
• yard expansion moving the fence West approximately 20 ft

Subject to Public Service Board approval, construction is scheduled to start in May 2011 and will be complete in October 2011.
