This bill creates a new state renewable energy excise tax on qualified wind and solar generation facilities and on large battery electric storage systems, and it authorizes county legislative authorities to impose a local renewable energy excise tax. It establishes an optional personal‑property tax exemption for specified personal property used primarily by those qualified renewable energy facilities and battery storage systems when owners follow notice/opt‑in procedures, and it sets reporting, payment timing, and enforcement procedures. The measure defines key terms (qualified facility, battery electric storage system, energy storage, repowering), requires annual and event‑based reports to the department and county assessors/treasurers, and includes opt‑in windows for projects that begin or repower during specified date ranges; exemptions and taxes automatically apply after specified long‑term operation thresholds. The text references specific excise tax rates per megawatt and per megawatt‑hour but those numeric rates are not included in the extracted facts. The act also creates a state local investment distribution account to receive state excise tax receipts and directs the (unnamed) department to establish a renewable energy development local investment distribution program to provide funds to counties that host qualifying energy projects. Counties must distribute those funds to local taxing districts by levy share unless a rural county elects to retain funds. The department must publish a model ordinance for siting and decommissioning standards, provide technical assistance, and implement a biennial tribal capacity grant program; the legislature expresses funding intentions for fiscal 2028 and thereafter. The act repeals four 2023 statutes related to renewable generation/storage taxes and creates related administrative and rulemaking authority. Other statutory changes include amendments to local levy law and levy calculation procedures (including adding assessed‑value increases for certain biomass and geothermal electricity facilities), new public hearing and ordinance/resolution requirements before taxing districts may increase property tax revenue, and authorization for a county to impose a special local renewable energy excise tax tied to excess levies beginning January 1, 2031. The Department of Revenue may disclose to local taxing officials the identity and tax information of persons subject to the new renewable energy excise taxes; improper disclosure by personnel who obtain tax information is made a misdemeanor with employment forfeiture consequences for state employees. The act takes effect January 1, 2028, with certain sections applying to property taxes levied for collection in 2028 or 2029 and additional deadlines for JLARC review and other dates noted in the extracted text. Important gaps in the provided excerpts: the specific numeric tax rates and the full text of several referenced sections (including section 106 opt‑in procedures, the complete description of section 116 and the local investment distribution account mechanics, and the unnamed department responsible for program administration) are not included in the extracted facts, so those details are uncertain from the material provided.

If enacted, the state will add a renewable energy excise tax on utility‑scale wind, solar, and large battery storage and allow counties to impose their own local excise tax; owners can avoid property tax on specified equipment by opting into the excise tax (or automatically after long operation or repowering). Projects and storage systems must file annual and event reports, pay state taxes monthly and local taxes semiannually if a county adopts the tax, and receipts from the state excise tax will flow into a new local investment distribution account used to send money to counties that host qualifying projects and to a tribal capacity grant program. The parties most affected are project developers and owners, county governments and local taxing districts, and federally recognized tribes. Developers gain the option to trade a property tax liability for a new excise tax but will face new reporting, notice, and payment obligations and potential new local levies; counties must adopt or align siting ordinances with a state model to qualify for distribution funds, must distribute receipts to taxing districts (unless a rural county elects to keep them), and county assessors must make repowering and eligibility determinations; tribes are eligible for dedicated capacity grants. Key details needed to estimate revenues or costs are missing from the extracted text — for example the exact tax rates, the named administering agency for some programs, and some opt‑in procedures — so the dollar impacts and precise eligibility outcomes are uncertain.
