Energy (Solar)

Substitute Senate Bill 5431 modifies certain tax and revenue laws without impacting state or local tax collections. It updates legislative intent regarding the extension of preferential tax rates for manufacturers and wholesalers in the solar silicon industry, tying future extensions to employment and wage growth criteria. Additionally, the bill amends rules for sellers concerning their personal liability for uncollected sales tax. It clarifies conditions for sellers to be relieved from this liability, including removing the requirement for them to renew blanket exemption certificates for recurring customers.

HB 1598 establishes rules for community solar programs in Washington to ensure equitable access to clean energy. It requires community solar projects (max 5,000 kW capacity) to have at least 30% of their capacity subscribed by low-income households (defined as 80% of area median income or 200% of federal poverty level) and 50% by residential subscribers. The bill creates "community solar bill credits" that automatically apply to subscribers' utility bills, allowing renters and income-qualified households to benefit without installing rooftop solar. It also sets site requirements (e.g., avoiding farmland) and defines key terms like "low-income service provider" to standardize program implementation. This directly affects low-income residents, renters, and communities unable to access traditional solar installations.

HB 1981 allows Washington counties to impose a 3% local tax on the sale or transfer of renewable energy facilities (like wind and solar farms) if approved by voters in a county election. The tax would apply to the seller of the facility, with proceeds becoming general county revenue. It aims to direct income from these projects back to rural communities where they operate, addressing concerns about limited local economic benefits. Counties must hold a vote to implement this tax, which would take effect January 1, 2026.

HB 1871 creates a state incentive program to help homeowners install grid-connected residential battery storage systems, primarily benefiting low- and moderate-income households. Utilities must establish approved incentive programs requiring at least 40% of benefits to reach these households, with options for time-of-use electricity rates or participation in utility-run virtual power plants. The program mandates income verification for qualifying customers, prohibits leasing, and requires utilities to document costs and protect customer data. Approved programs must be audited biennially by Washington State University Extension. The bill aims to increase grid resilience during outages while supporting clean energy goals.
