This bill introduces a new chapter, Chapter 46, to Title 63 of the Idaho Code, which establishes a county excise tax on commercial wind turbines. It defines key terms related to commercial wind turbines, including "commercial wind turbine," "component parts," "height," "intended height," and "nameplate capacity." The bill mandates that county commissioners must conduct a preference election to gauge public support for proposed commercial wind turbine projects. If a majority of voters disapprove, the county must enact an ordinance to impose a one-time excise tax on the storage, use, or consumption of any commercial wind turbine exceeding 100 feet in height, calculated at a rate of $25,000 per foot, with annual inflation adjustments.

Additionally, the bill outlines the procedures for tax collection and administration, requiring counties to contract with the state tax commission. It specifies that the tax will not apply to turbines owned by government entities or Idaho Indian tribes. The tax revenues will be allocated to various funds, including the school district facilities fund. The bill also grants the state tax commission the authority to enforce the provisions and adopt necessary rules for implementation. An emergency clause is included, allowing the act to take effect immediately upon passage and approval.
