House committee advances S.50 to raise expedited net‑metering cap, debates municipal setbacks and REC rules

The Vermont House Energy and Digital Infrastructure Committee met April 9 to review S.50, a bill the committee is preparing to move to the floor that would raise the expedited net‑metering registration threshold used by the Public Utility Commission (PUC) from 15 kilowatts (kW) to 25 kW.

Committee chair Representative Kathleen James said the change would “ratchet up the kilowatts that would apply to this registry,” arguing the increase responds to improvements in panel efficiency that allow more output without substantially larger ground‑mounted arrays.

The bill would direct the PUC to allow projects 25 kW and smaller to use the faster registration procedure while the agency updates its formal rules. PUC staff told the committee that formally rewriting the net‑metering rule will likely take many months, but that the commission can change its online registration form and related materials more quickly. A PUC representative said rule revisions typically take at least eight months and often approach a year when contested changes are proposed.

Why it matters

Raising the expedited threshold would cover a class of ground‑mounted residential systems that installers described as ‘‘backyard’’ arrays—systems larger than rooftop installations but sized for a single home. Renewable Energy Vermont witness Peter Sterling told the committee, “These ground mounts are backyard solar arrays almost exclusively,” and said economics and electrical design generally keep arrays within roughly 1,200 feet of the customer meter.
