House moves to raise expedited net‑metering cap to 25 kilowatts

The Vermont House of Representatives voted on the floor to propose to the Senate an amendment to Senate Bill 50 that raises the expedited registration cap for ground‑mounted residential net‑metering projects from 15 kilowatts to 25 kilowatts and ordered the bill for third reading.

The change is intended to reflect improvements in panel efficiency and allow homeowners to install somewhat larger ground‑mounted systems without triggering the longer Public Utility Commission (PUC) review process. "25 is the new 15," Representative James (member from Manchester) said while presenting the committee report.

Representative James, speaking for the House Energy and Digital Infrastructure Committee, described S.50 as "a narrowly crafted bill" that leaves the substantive approval process with the PUC. Under current practice the expedited registration requires the PUC to notify the utility, which then has 10 days to review the project; if the utility signs off the PUC issues a certificate of public good (a permit). The bill raises the expedited cap for ground‑mounted systems from 15 kW to 25 kW and adds a statewide minimum setback of 10 feet from highways and property boundaries for systems smaller than 25 kW.

The bill also makes three other changes detailed by the sponsor: it allows a customer who installs a small solar system to change their decision about assigning the renewable energy credit (REC) to the utility once, but only within 120 days after the system goes online; it eliminates a redundant requirement that installers separately file proof with the PUC that a certificate of public good was recorded in municipal land records; and it asks the PUC to convene stakeholders and recommend an updated statutory definition of a larger solar "plant" for the Legislature to consider.

An amendment offered from the floor by Representative North (member from Ferrisburg) that would have repealed the state's clean heat standard was ruled not germane by the chair after a point of order by the member from Hartland. The chair found that repealing the clean heat standard would change the purpose of S.50 and therefore could not be considered as an amendment to the bill.

The committee report noted broad input in drafting the bill, including conversations with the Public Utility Commission, Renewable Energy Vermont, Green Mountain Power, the Vermont League of Cities and Towns, VPIRG, and multiple solar companies. S.50 was unanimously recommended by the House Energy and Digital Infrastructure Committee on a 9‑0‑0 vote. The House took the committee recommendation by voice vote; the clerk recorded that "the ayes have it" and third reading was ordered.

Why this matters: raising the expedited cap allows many homeowners to add capacity for electric vehicles or heat pumps without incurring a lengthier PUC process. The PUC is asked to return to the Legislature with a recommendation next November about how to define larger solar plants, a step the bill frames as necessary to balance land‑use considerations with the goal of siting solar efficiently.

Key details clarified on the floor: the expedited review process still involves PUC notification and a 10‑day utility review; the REC assignment change is allowed only once and only within 120 days after a system goes online; the statewide minimum setback for systems under 25 kW is 10 feet; the bill's effective date is July 1, 2025.

The House presentation emphasized that S.50 does not otherwise change how residential or commercial arrays are approved; it adjusts thresholds and some administrative requirements to reflect modern panel performance and to reduce redundant filings.

Provisions discussed but not decided on the floor include the PUC's future work on the statutory definition of a "plant" (the committee asked the PUC to convene stakeholders and report back in November).
