Michigan Compiled Laws, Chapter 460. Public Utilities § 460.1039

(a) If a renewable energy system uses both a renewable energy resource and a nonrenewable energy resource to generate electricity or steam, the number of renewable energy credits granted shall be based on the percentage of the electricity or steam, or both, generated from the renewable energy resource.

(b) A renewable energy credit shall not be granted for renewable energy the renewable attributes of which are used by an electric provider in a commission-approved voluntary renewable energy program.

(c) For a renewable energy system described in section 11(j)(iii),  2 for each megawatt hour of electricity generated from the renewable energy system before 2040, 0.5 renewable energy credits shall be granted. No renewable energy credits shall be granted for electricity generated in 2040 or thereafter. A renewable energy system described in section 11(j)(iii) shall, by January 1, 2035, file a decommissioning plan with the county in which the facility is located detailing its plans to retire and decommission the facility not later than January 1, 2040.

(a) 2 renewable energy credits for each megawatt hour of electricity from solar power generated by a renewable energy system that was approved in a renewable energy plan before April 20, 2017.

(b) 1/5 renewable energy credit for each megawatt hour of electricity generated from a renewable energy system, other than wind, at peak demand time as determined by the commission.

(c) 1/5 renewable energy credit for each megawatt hour of electricity generated from a renewable energy system during off-peak hours, stored using an energy storage system or a hydroelectric pumped storage facility, and used during peak hours. However, the number of renewable energy credits shall be calculated based on the number of megawatt hours of renewable energy used to charge the energy storage system or fill the pumped storage facility, not the number of megawatt hours actually discharged or generated by discharge from the energy storage system or pumped storage facility.

(d) 1/10 renewable energy credit for each megawatt hour of electricity generated from a renewable energy system constructed using equipment made in this state as determined by the commission. The additional credit under this subdivision is available for the first 3 years after the renewable energy system first produces electricity on a commercial basis.

(e) 1/10 renewable energy credit for each megawatt hour of electricity from a renewable energy system constructed using a workforce composed of residents of this state as determined by the commission. The additional credit under this subdivision is available for the first 3 years after the renewable energy system first produces electricity on a commercial basis.

(a) When used by an electric provider to comply with its renewable energy standard.

(b) When substituted for an energy waste reduction credit under section 77.  3

(c) Five years after the end of the month in which the renewable energy credit was generated.
