West Rutland Substation Upgrade
In 2010, VELCO proposed to upgrade the West Rutland substation in West Rutland, Vermont, to improve the reliability of the electric facilities serving the customers of Vermont.
Needs & Benefits
VELCO constructed the West Rutland substation in 1969 to support and maintain system reliability for the Vermont electric system. Around 2006, VELCO made upgrades to the substation as part of the Northwest Reliability Project.
Transmission utilities, such as VELCO, are required to design, operate and maintain a transmission network according to national and regional reliability standards. Planning studies by VELCO and ISO New England, New England's bulk electric system provider, reveal that the existing West Rutland substation does not meet current federally mandated reliability requirements.
As outlined in VELCO's 2006 and 2009 Long-Range Transmission Plan, the vulnerability of the current substation design results in system reliability problems, which under certain circumstances may lead to loss of service, system outages and low voltage. These concerns can be addressed by installing the two capacitor banks.
- Two new capacitor banks
- New disconnect switches
- New buswork
- Protection equipment
- Fence expansion
VELCO's aesthetic consultant reviewed the preliminary design plans and performed a visual analysis of the areas of the proposed Project. The findings indicated that the views to the site are distant, obstructed by foreground and distant vegetation as well as the road alignment. Planting plans were developed for mitigation during the construction of the substation. A full analysis of potential aesthetic impacts and proposed mitigation measures was included with the project petition.
