Vermont Public Utility Commission Approves Non-Substantial Change in Airport Substation Project

Strategic Insights

— 1 min read

The Vermont Public Utility Commission (PUC) has issued an order approving a non-substantial change determination for the construction of a new Airport Substation in South Burlington, Vermont. The original certificate of public good (CPG) was issued to Green Mountain Power Corporation (GMP) in 2019, authorizing the construction of the new substation and the decommissioning of the existing one. GMP requested an extension of the project timeline to accommodate the Vermont Air National Guard's (VANG) requirement for additional time to perform a necessary voltage conversion.

Key Takeaways:

  • The PUC has approved a non-substantial change determination for the Airport Substation project, allowing GMP to extend the project timeline until June 30, 2024.
  • The requested extension is to accommodate the VANG's requirement for additional time to perform a necessary voltage conversion, which cannot be completed until September 30, 2023.
  • The PUC found that the proposed changes do not have the potential for significant impacts on the Section 248 criteria or on the general good of the State under Section 248(a).
  • GMP's supplemental testimony and exhibit supporting the petition have been admitted into the evidentiary record.
  • The CPG requires that construction of the project be done in accordance with the plans and evidence submitted in the proceeding.

Statistics:

  • The original CPG was issued in 2019.
  • The VANG requires additional time to perform a necessary voltage conversion, with a completion date of September 30, 2023.
  • GMP is allowed to decommission the original Airport Substation and remove its related components until June 30, 2024.
  • The PUC has approved a non-substantial change determination for the Airport Substation project.
  • The PUC received no other comments on GMP's proposal, aside from the Vermont Department of Public Service (DPS), which filed comments on October 20, 2022.
