Grant County, WA — Solar Development Risk Assessment

No Moratorium

Grant County: setback requirements codified for utility-scale solar per county code; specific distances from property lines, roads, and residences per county ordinance.

Grant County: CUP in Agricultural (AG) and Resource zones; Grant County Planning Commission and Board of County Commissioners. Grant PUD coordinates interconnection review in parallel.

Supportive — Grant County PUD is the most solar-proactive utility in WA; county board aligned with energy development; Columbia Basin plateau has ideal terrain and irradiance; strong BPA backbone

Grant County PUD serves entire county; electric rates among lowest in WA due to Columbia River hydro; county board actively courts solar investment; Columbia Basin dryland/irrigated land transition supports agrivoltaics; BPA Grand Coulee-area substations provide backbone; Grant County is widely considered prime solar development territory in WA

Improving

Large facilities (≥350 MW nameplate): Washington EFSEC (Energy Facility Site Evaluation Council) has exclusive siting jurisdiction — state agency preempts all local permitting. Projects <350 MW: county-level conditional use permit (CUP) or special use permit (SUP) in agricultural or resource-zoned land; no statewide preemption floor for smaller projects. SEPA (State Environmental Policy Act): environmental review required for utility-scale projects; DNS, MDNS, or full EIS depending on county SEPA lead agency threshold. Growth Management Act (GMA): 29 WA counties must incorporate energy siting in comprehensive plans; some have adopted renewable energy elements. Shoreline Management Act (SMA): projects near shorelines require Shoreline Substantial Development Permit. Critical Areas Ordinances (CAO): wetlands, fish/wildlife habitat, flood zones, and geologically hazardous areas require county CAO compliance review. Agricultural land: county-specific farmland protection policies apply; prime farmland conversion may require additional findings under county comprehensive plan.

Washington Clean Energy Transformation Act (CETA/SB 5116, 2019): IOUs must be carbon-neutral by 2030; 100% carbon-free by 2045. Net metering: ≤100 kW for IOU customers (PSE, Avista, Pacific Power) under WUTC; PUDs set individual limits, most allow up to 100% of annual consumption offset. RESIP (Renewable Energy System Incentive Program): production-based incentives for systems ≤100 kW, funded by utilities under WUTC mandate. Sales & use tax exemption: solar PV equipment fully exempt (RCW 82.08.962). Property tax exemption: solar systems excluded from assessed value (RCW 84.36.635). Community solar: available through PSE, SnoPUD, Tacoma Power, Clark Public Utilities, and most WA PUDs. PACE financing: available in participating WA counties. Federal ITC: 30% investment tax credit (IRA 2022) for commercial and residential. Low-income adder: 10% bonus ITC for projects serving income-qualified communities (IRA §48E).

Numerous large utility-scale solar projects online and in permitting: Lund Hill Solar (300+ MW, one of largest solar farms in WA); multiple 20–150 MW projects along Columbia Basin plateau; Grant County PUD interconnection queue among most active in Pacific Northwest.

No formal denials on record; BPA interconnection queue congestion has delayed some project timelines but no county-level rejections.
