(b) "Renewable energy" means energy produced by a solar or wind facility with nameplate capacity sufficient to generate at least one megawatt of nameplate capacity of alternating current power.

(c) "Renewable energy storage system" means battery storage or battery energy storage system that can store renewable energy when production exceeds demand and release energy when energy demand increases.

NEW SECTION. Sec. 3. (1) The renewable energy local benefit account is created in the state treasury. All receipts from the production excise tax in section 2 of this act must be deposited in the account. Moneys in the account may be spent only after appropriation.

(b) Qualified federally recognized Indian tribes must receive an appropriation totaling 15 percent of the production excise tax paid by a renewable energy system impacting the tribes' resources or rights, in proportion to the number of enrolled members of each qualified federally recognized Indian tribe.

(c) Each qualified school district must receive an appropriation from the remaining 42.5 percent of the production excise tax paid by a renewable energy system located in the same county in proportion to the number of students being served by that district.
