Permit Design builds Wyoming solar permit plan sets for licensed solar installers, EPCs, and roofing companies statewide. Rocky Mountain Power (a PacifiCorp subsidiary, owned by Berkshire Hathaway Energy) serves Casper, Laramie, Gillette, Rock Springs, Green River, Rawlins, and most of Wyoming with net metering under Wyoming Public Service Commission oversight. Black Hills Energy serves Cheyenne and southeastern Wyoming. Each utility has its own interconnection application — confirm utility per address before building every Wyoming plan set.
Wyoming solar plan sets require ASCE 7 cold climate structural calculations for snow loads of 20 to 40 psf depending on location, with higher values in the mountains around Jackson and Cody. Wyoming's high plains also produce extreme wind loads that must be included in the structural section alongside snow calcs. High altitude — Cheyenne at 6,062 feet, Laramie at 7,165 feet, Casper at 5,150 feet — improves solar panel output by reducing atmospheric attenuation. Wyoming has no state income tax. NEC 2020 applies statewide under the Wyoming State Building Code.
Wyoming permitting is administered at the city and county level. Cheyenne (Laramie County) uses the Cheyenne Planning and Development Services permit office. Casper (Natrona County) uses the Casper Building Division. Laramie (Albany County) uses the Laramie Building Department. Gillette (Campbell County) and Rock Springs (Sweetwater County) each have separate city permit offices. Rocky Mountain Power interconnection is submitted simultaneously with the building permit for most Wyoming projects. Black Hills Energy interconnection is submitted for Cheyenne and eastern Wyoming projects. ASCE 7 cold climate snow calcs (20–40 psf per location) and northern plains wind calcs are required in every Wyoming structural section. High altitude improves solar panel output at every Wyoming address.
Rocky Mountain Power Serves Most of Wyoming. Black Hills Energy Serves Cheyenne and Eastern WY. Separate Interconnection Applications Under Wyoming PSC. Utility Confirmed Per Address Before Building.

Also doing commercial rooftop, carport, or ground-mount in Wyoming?
Wyoming commercial solar structural packages reference IBC 2021 with NEC 2020 electrical throughout. Rocky Mountain Power and Black Hills Energy both offer commercial net metering under Wyoming PSC oversight.

Wyoming Solar Permit Design — Installer FAQ
Rocky Mountain Power (a PacifiCorp subsidiary, owned by Berkshire Hathaway Energy) serves Casper, Laramie, Gillette, Rock Springs, Green River, Rawlins, Sheridan, Cody, and most of Wyoming with net metering under Wyoming PSC oversight. Black Hills Energy serves Cheyenne, Torrington, Wheatland, and eastern Wyoming. Some Cheyenne addresses may be served by Rocky Mountain Power rather than Black Hills Energy — confirm per address. Jackson Hole and Teton County may be served by a separate cooperative. We confirm utility per address before building every Wyoming plan set.
Yes. Rocky Mountain Power and Black Hills Energy both offer net metering for qualifying residential solar systems under Wyoming Public Service Commission oversight. Net metering credits exported solar at the retail electricity rate. Wyoming PSC rules govern both utilities' net metering programs. Credit terms, system size limits, and interconnection requirements may differ between Rocky Mountain Power and Black Hills Energy — confirm current program terms with the specific utility per address before finalizing system economics. Wyoming's net metering combined with no state income tax creates a clean financial picture for solar.
Wyoming net metering is available from Rocky Mountain Power and Black Hills Energy under Wyoming PSC oversight — the primary financial driver for Wyoming solar customers. Wyoming has no state income tax on individuals or corporations, which means no state solar income tax credit is possible but also means no state tax layer in solar financial modeling. Wyoming Stat. Section 39-11-105 provides a property tax exemption for qualifying solar and wind energy systems — solar installations that increase assessed property value are exempt from the tax increase. Wyoming's high altitude (5,000-7,000+ feet at Cheyenne, Laramie, Casper, and Jackson) improves solar panel output by approximately 4 to 6% versus sea-level installations in the same climate — a meaningful production uplift that improves financial returns. No Wyoming state solar income tax credit exists in 2026. Federal 25D residential credit expired December 31, 2025.
NEC 2020 under the Wyoming State Building Code, administered by the Wyoming Department of Fire Prevention and Electrical Safety. Article 690 governs Wyoming solar PV system design. Article 706 governs energy storage systems. Article 625 governs EV charging. IBC 2021 and IRC 2021 are Wyoming's structural standards. Some Wyoming municipalities may maintain local code amendments — confirm with the specific AHJ before finalizing plan set content.
Yes — both are required in every Wyoming plan set structural section. Wyoming ground snow loads vary by location: Cheyenne approximately 20 psf, Casper approximately 25 psf, Laramie approximately 30 psf, Jackson approximately 40 psf. Wyoming's high plains also produce extreme wind loads — Wyoming is among the windiest states in the US and ASCE 7 wind calcs must be included alongside snow calcs. Plan sets submitted to Wyoming AHJs without both cold climate snow calcs and high plains wind calcs in the structural section fail plan review.
Yes — positively. Wyoming sits at significant elevation: Cheyenne at 6,062 feet, Laramie at 7,165 feet, Casper at 5,150 feet, Jackson at 6,237 feet. At high altitude, the atmosphere is thinner, which reduces solar radiation attenuation. Wyoming solar panels produce approximately 4 to 6% more output per installed watt compared to sea-level installations in the same climate receiving the same sunlight duration. Combined with Wyoming's strong 5.0 to 5.5 peak sun hour resource, high altitude meaningfully improves annual system production and financial returns.
Wyoming has no statewide PE stamp requirement for standard residential rooftop solar installations. Rocky Mountain Power territory AHJs — Casper, Laramie, Gillette, Rock Springs, Green River, and Rawlins — do not require a PE stamp for standard residential rooftop solar plan sets. Black Hills Energy territory AHJs — Cheyenne and eastern Wyoming — similarly do not require PE stamps for standard residential installations. Commercial solar installations in Wyoming require PE-stamped structural drawings regardless of system size. Ground-mount systems of all sizes require PE-stamped structural engineering including combined ASCE 7 cold climate snow load and high plains wind load analysis — Wyoming ground-mount engineering is among the more demanding in the western US given the combined wind and snow exposure. Jackson Hole (Teton County) residential projects at 40 psf snow load may occasionally prompt PE review requests from the Teton County Building Department — confirm per project before ordering. Permit Design coordinates PE stamp services for Wyoming commercial and ground-mount projects upon request.
Most Wyoming 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.
