The proposed bill aims to encourage local support for communities hosting renewable energy facilities by allowing counties to impose an excise tax on the nameplate capacity of industrial-scale renewable energy facilities. Counties can submit a proposition to voters for approval, and if passed, they can implement a tax with specific rates based on the type of renewable energy facility. The tax rates are set to adjust annually for inflation starting January 1, 2026, and vary for solar and wind energy production facilities based on their operational dates, as well as for battery energy storage facilities. The tax will expire after a specified number of years unless resubmitted to voters for continuation.

Additionally, the bill establishes definitions for key terms such as "consumer price index" and "industrial-scale renewable energy facility." It is structured as a new chapter in Title 82 RCW and includes a declaration of emergency, indicating that the act is necessary for the immediate preservation of public peace, health, or safety, and will take effect immediately upon passage.
