Committee hears testimony on bill to raise expedited net-metering cap for ground-mounted residential solar

Summary

Lawmakers and stakeholders debated S.50, which would raise the expedited registration limit for ground-mounted residential net-metering systems from 15 kW to 25 kW, with witnesses and members discussing technical changes in panel efficiency, customer economics, interconnection safeguards and the measure of any utility cost shift.

The House Energy and Digital Infrastructure Committee took testimony March 24 on S.50, a proposal to raise the size threshold that qualifies ground-mounted residential solar systems for the expedited net‑metering registration process from 15 kilowatts (kW) to 25 kW.

Proponent Peter Sterling of Renewal Energy told the committee the bill targets small, on‑site systems and would make it easier for homeowners who want to electrify their homes to install larger backyard arrays. “Net metering allows people to generate solar power for their own use and then send extra solar power to the grid from where they live and work,” Sterling said. He added modern panels are substantially more efficient than panels available when the original 2014 rule was written: “25 is the new 15,” he said, arguing the same physical footprint now yields materially more generation.

The bill would not change rooftop thresholds, Sterling emphasized. Under current Vermont practice, rooftop systems up to 500 kW use the fast application process; S.50 addresses only…
