Grays Harbor County, WA — Solar Development Risk Assessment

No Moratorium

No county-specific solar setbacks; standard county zoning setbacks apply.

Grays Harbor County: CUP in Agricultural and Resource zones; Grays Harbor County Planning Dept and Board of County Commissioners.

Cautious/neutral — coastal economy; low irradiance fundamentally limits utility-scale viability; timber and fishing identity; Aberdeen port area has some brownfield redevelopment interest

Pacific Power and Grays Harbor PUD serve county; county board neutral; Aberdeen and Hoquiam post-industrial communities have economic development interest but solar economics poor at 3.2 kWh/m²/day; Olympic National Forest restricts northern land

Stable

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).

Very limited utility-scale solar; some residential rooftop in Aberdeen and Hoquiam; Pacific Power net metering; minor commercial rooftop at industrial port facilities.

No formal denials on record; limited developer interest due to irradiance constraints.
