Green Mountain Power Serves 75% of Vermont With Among the Strongest Net Metering Terms in the US. Vermont Electric Cooperative Serves Rural Northeastern Vermont Under the Same Net Metering Framework.
Permit Design builds Vermont solar permit plan sets for licensed solar installers, EPCs, and roofing companies statewide. Green Mountain Power (GMP) serves approximately 75% of Vermont — Burlington, Montpelier, Rutland, Barre, St. Johnsbury, Brattleboro, and surrounding communities — with net metering available under Vermont Public Utility Commission oversight. Vermont Electric Cooperative (VEC) serves rural northeastern Vermont including the Northeast Kingdom. Vermont has one of the strongest net metering frameworks in the United States under the Vermont Renewable Energy Standard.
Vermont solar plan sets require heavy New England cold climate snow loads — 40 to 60+ psf depending on location and elevation. Vermont's Green Mountains and higher elevations see the heaviest values. NEC 2020 applies statewide under the Vermont Division of Fire Safety. Vermont's strong renewable energy policy — including the Vermont Renewable Energy Standard (RES) and net metering — has made Vermont a consistent leader in solar installations per capita among all US states.
Vermont permitting is administered at the town level — Vermont has no county government. Every Vermont municipality has its own zoning and building permit process. Burlington (Chittenden County) uses the Burlington Development Review Office. South Burlington, Williston, Colchester, and Shelburne each have separate town permit offices. Vermont's Green Mountain Power covers approximately 75% of customers — GMP interconnection is submitted simultaneously with the town permit. NH Electric Cooperative covers rural northeastern Vermont — VEC interconnection is submitted simultaneously. Vermont's heavy snow loads (40–60+ psf) are the most critical structural factor in Vermont solar plan sets and the most common rejection cause for out-of-state templates.

Vermont Solar Permit Design — Installer FAQ
Green Mountain Power (GMP) serves approximately 75% of Vermont customers including Burlington, South Burlington, Montpelier, Rutland, Barre, St. Johnsbury, and Brattleboro. GMP offers full retail net metering under Vermont Public Utility Commission oversight. Vermont Electric Cooperative (VEC) serves rural northeastern Vermont — the Northeast Kingdom counties of Essex, Orleans, and Caledonia. VEC offers net metering under the same Vermont PUC framework. A small portion of Vermont is served by Eversource Vermont. We confirm GMP or VEC utility per address before building every Vermont plan set.
Yes — Vermont has among the strongest net metering programs in the United States. Green Mountain Power and Vermont Electric Cooperative offer full retail net metering under Vermont Public Utility Commission oversight and the Vermont Renewable Energy Standard. Full retail 1:1 net metering means every exported kilowatt-hour earns a credit at the full retail electricity rate. Vermont's net metering is consistently ranked among the top programs nationally. Monthly excess credits roll forward. Vermont's combination of strong net metering, sales tax exemption, and property tax exemption creates one of the most compelling solar incentive stacks in New England.
Vermont has a strong multi-part incentive stack. GMP and VEC full retail net metering under Vermont PUC oversight is the primary financial driver. Vermont exempts solar equipment from state sales tax — a 6% savings on all hardware. Vermont 32 V.S.A. Section 3845 exempts solar energy systems from municipal property tax on added assessed value. Vermont's Renewable Energy Standard (RES) supports the solar REC market. No Vermont state solar income tax credit exists in 2026. Federal 25D residential credit expired December 31, 2025.
NEC 2020 under the Vermont Division of Fire Safety, Department of Public Safety. Vermont adopted NEC 2020 statewide for all electrical installations including solar PV systems. Article 690 governs Vermont solar PV system design — including rapid shutdown requirements (Section 690.12), array wiring methods, string sizing, inverter disconnect placement, and system labeling. Article 706 governs energy storage systems (battery installations). Article 625 governs EV charging equipment. IBC 2021 and IRC 2021 are Vermont's current structural standards. Vermont's heavy snow loads (40-60+ psf) interact directly with the structural requirements of IBC/IRC 2021 — the combination of NEC 2020 electrical requirements and Vermont-specific ASCE 7 structural requirements creates a plan set environment where both must be correct for Vermont AHJ approval. Some Vermont municipalities may have local amendments — confirm with the specific town building official before finalizing plan set content.
Yes — Vermont has heavy New England snow loads that are among the highest in the continental United States. Burlington sees approximately 40 psf ground snow load. Montpelier sees approximately 50 psf. The Green Mountains and higher elevations see 60+ psf. These loads are significantly heavier than Midwest markets and require robust ASCE 7 cold climate structural calculations in every Vermont plan set. Northeast Kingdom elevations in VEC territory can be particularly heavy. We confirm ASCE 7 ground snow load per specific address for every Vermont plan set.
Vermont has no statewide PE stamp requirement for standard residential rooftop solar installations. Green Mountain Power territory AHJs — Burlington, South Burlington, Montpelier, Rutland, Barre, and Brattleboro — do not require a PE stamp for standard residential rooftop solar plan sets. Some Vermont municipalities with complex structural conditions, historic districts, or unusual roof configurations may request PE-stamped drawings — confirm with the specific town building official before ordering. Commercial solar installations require PE-stamped structural drawings. Ground-mount systems of all sizes require PE-stamped structural engineering including Vermont-specific heavy snow and wind load analysis. Green Mountains elevation projects — Stowe, Killington area, Smugglers Notch — may warrant PE review of snow load calcs given the elevated ASCE 7 values at those locations. Permit Design coordinates PE stamp services for Vermont commercial and ground-mount projects.
Vermont leads New England in solar installations per capita — consistently ranked in the top five US states per capita despite its northern latitude and short winter days. This leadership is driven by GMP's strong full retail net metering, Vermont's solar sales tax exemption (6% on all equipment), property tax exemption (32 V.S.A. Section 3845), and the Vermont Renewable Energy Standard that creates ongoing REC demand. GMP is also unique among US utilities for innovative virtual net metering and battery programs. Vermont's heavy snow loads (40–60+ psf depending on location and elevation) mean that structural engineering quality is a genuine differentiator in Vermont plan sets — plan sets from firms without Vermont-specific snow load knowledge routinely fail Vermont building official review. Vermont's two-utility structure — GMP for approximately 75% of customers and Vermont Electric Cooperative for the Northeast Kingdom — requires utility confirmation per address before building.
Most Vermont residential solar permit plan sets are delivered in 24 to 48 hours from project submission. Battery storage plan sets ship same day. Commercial solar: 3 to 5 business days.
