Board Sentiment & Political Risk

Sentiment Analysis
Supportive — SnoPUD among most progressive WA PUDs for solar; county board supportive; aerospace industry corporate sustainability goals drive commercial solar
Basis for Assessment
SnoPUD (Snohomish County PUD) serves most of county; PSE serves some areas; Boeing Everett plant is largest building by volume in world with massive commercial rooftop potential; Paine Field aviation may restrict some airspace; rapid suburban growth in south county; strong BPA backbone at Everett substations
Political Risk Factors
Improving
Board Members
Snohomish County Council (5 members) | Partisan elections | 4-yr terms | Robert J. Drewel Building, Everett WA

Grid, Utilities & State Context

Grid Operator
WECC / BPA Transmission — SnoPUD and PSE service territory; Everett / Puget Sound grid
Utilities
Snohomish County PUD (SnoPUD), Puget Sound Energy (PSE)
State Permitting Process
Large facilities (≥350 MW): EFSEC exclusive jurisdiction. <350 MW: county CUP/SUP; no statewide preemption floor. SEPA review required. GMA energy siting required in comprehensive plans. SMA applies near shorelines. Critical Areas Ordinances: wetlands, fish habitat, flood zones require county CAO compliance. Ag land conversion: county-specific farmland protection policies apply.
State Incentives
Washington Clean Energy Transformation Act (CETA/SB 5116, 2019): IOUs carbon-neutral by 2030; 100% carbon-free by 2045. Net metering: ≤100 kW IOU customers under WUTC; PUDs set individual limits. RESIP: production incentives for ≤100 kW systems. Sales & use tax exemption (RCW 82.08.962). Property tax exemption (RCW 84.36.635). Community solar via PSE, SnoPUD, Tacoma Power, Clark Public Utilities, and most WA PUDs. PACE financing in participating counties. Federal ITC: 30% (IRA 2022); 10% low-income adder for qualifying projects.

Development Activity

Active/Completed Projects
Multiple commercial rooftop installations at Boeing Everett plant and supplier facilities; SnoPUD community solar program has enrolled hundreds of customers; growing residential pipeline in Marysville, Lynnwood, Edmonds; limited greenfield utility-scale due to suburban density.
Denied/Withdrawn Projects
No confirmed utility-scale denials; limited greenfield applications due to land availability.
