The proposed bill aims to encourage local support for communities hosting renewable energy facilities by allowing counties in Washington to impose an excise tax based on the nameplate capacity of industrial-scale renewable energy facilities. Counties can submit a proposition to voters for approval, and if passed, the tax rates are set according to the type of energy facility and adjusted annually for inflation starting January 1, 2026. Specific tax rates are outlined for solar and wind energy production facilities, as well as for battery energy storage facilities, with provisions for the tax to expire after a certain period unless renewed by voters.

Additionally, the bill establishes definitions for key terms such as "consumer price index" and "industrial-scale renewable energy facility." It is introduced as a new chapter in Title 82 RCW and is deemed necessary for the immediate preservation of public peace, health, or safety, allowing it to take effect immediately upon passage.
