Senate committee reviews House changes to S.50 on net‑metering, setbacks and REC reassignment

The Senate Natural Resources and Energy Committee met May 7 to review House amendments to S.50, a bill that updates Vermont’s net‑metering and small solar siting rules and directs follow‑up rulemaking at the Public Utility Commission.

The changes the committee reviewed include a one‑time opportunity for a customer to change whether they keep or transfer renewable energy credits (RECs) within 120 days after a net‑metering system is commissioned; a statewide 10‑foot minimum setback for small arrays where municipalities have no solar setback; removal of a duplicate filing requirement with town land records and the PUC’s online registry; and a stakeholder process to revisit the statutory definition of a single “plant.”

Why it matters: the amendments affect how small property owners, solar installers and distribution utilities account for RECs and how small rooftop and yard arrays are sited. Utilities told lawmakers that changes to REC ownership affect long‑term planning and budgets, while installers said consistent setbacks reduce the likelihood of post‑installation property disputes.

Top points

- One‑time REC reassignment window: The House language the committee reviewed would let any customer who owns a net‑metering system commissioned between Jan. 1, 2023 and July 1, 2025, change the customer’s decision to retain attributes one time by submitting a request to the PUC by Sept. 2, 2025. Rep. James, chair of the House Infrastructure, Energy and Digital Infrastructure Committee, told the Senate the House settled on a 120‑day window so owners “get a couple of bills and say, wait a second. Where are my savings?”

- Utilities’ concern and limits: Greg Faber of the Public Utility Commission said the 120‑day, one‑time window is important to avoid market gaming: “The utilities plan going forward for years at a time, they can’t afford to have that kind of market, playing in in their system.” The PUC said it does not object to the 120‑day proposal.

- Setbacks and small systems: The House added a statewide 10‑foot minimum setback for systems at or below the new small‑system threshold, replacing a patchwork approach that would have defaulted to differing municipal setbacks. Committee members and installers said installers typically check local rules and prefer to comply with the town setback; the 10‑foot minimum primarily protects properties in towns that have no solar setback on file.

- Definition of a “plant” and co‑location: The House language directs the PUC to convene stakeholders and report back with a recommended updated definition of a single plant that accounts for co‑location benefits, land‑use implications and potential ratepayer impacts. Peter Sterling, a guest representing a community college, said the statute’s original “single‑plant” rule had prevented developers from “gaming the system” but added that the policy should be updated so larger projects can be co‑located on already‑disturbed sites without unnecessary new roads or poles: “That single plan worked very well, and I think it had its intended effect.”

- Paperwork change: The House removed an earlier requirement for installers to file proof with both town land records and the PUC. Committee members said the PUC’s online registration (EPUC) and searchable town land records make double reporting redundant.

Committee action and next steps

Senators gave informal assent by straw poll to move forward with the House changes and the proposed amendment language; there was no formal roll call vote recorded in the transcript. The bill as amended will require the PUC to update rules to reflect the statutory changes and to convene the stakeholder process on the plant definition and report back as directed in the bill.

What remains unsettled: lawmakers noted the tradeoffs between more time for customers to discover billing impacts and utilities’ need for stable planning assumptions; the 120‑day window was chosen as a compromise. The stakeholder process on the plant definition was left to the PUC with a report timeline noted in the bill.
