(1) uses:

(i) primarily animal manure, including poultry litter, and associated bedding to generate thermal energy; and

(ii) food waste or qualifying biomass for the remainder of the feedstock;

(2) is used in the State; and

(3) complies with all applicable State and federal statutes and regulations, as determined by the appropriate regulatory authority.

(i) “Renewable energy credit” or “credit” means a credit equal to the generation attributes of 1 megawatt-hour of electricity that is derived from a Tier 1 renewable source or a Tier 2 renewable source that is located:

(1) in the PJM region; or

(2) outside the area described in item (1) of this subsection but in a control area that is adjacent to the PJM region, if the electricity is delivered into the PJM region.

(j) “Renewable energy portfolio standard” or “standard” means the percentage of electricity sales at retail in the State that is to be derived from Tier 1 renewable sources and Tier 2 renewable sources in accordance with § 7-703(b) of this subtitle.
