In re Petition of Portland Street Solar LLCAnnotate this Case
Portland Street Solar LLC appealed a Public Utility Commission order denying Portland Street’s petition for a certificate of public good (CPG) to install and operate a 500-kW solar group net-metering system adjacent to a previously permitted solar array owned by Golden Solar, LLC. Interpreting the definition of “plant” set forth in 30 V.S.A. 8002(18), the Commission determined that the proposed Portland Street project would be part of a single plant along with the already-approved adjacent Golden Solar project and thus would exceed the 500-kw energy-generating-capacity limit applicable in the net-metering program. On appeal, Portland Street argued the Commission’s decision was inconsistent with the Vermont Supreme Court’s controlling precedent, as well as prior Commission decisions involving similar cases, and that the Commission exceeded its statutory authority by expansively construing the component parts of section 8002(18) that defined the characteristics of a single plant. Applying the appropriate deferential standard of review, the Supreme Court concluded the Commission’s self-described expanded and refined interpretation of what constituted a single plant under section 8002(18) was not arbitrary, unreasonable, or discriminatory and did not amount to compelling error that would require the Court to intervene in matters the Legislature has delegated to the Commission’s expertise. Accordingly, the Court affirmed the Commission’s decision denying Portland Street’s petition for a CPG to install and operate its proposed facility under the net-metering program.
