This area includes all or parts of Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and the District of Columbia.
Qualifying biomass - a solid, non-hazardous, cellulosic waste material that is segregated from other waste materials, and is derived from any of the following forest-related resources, with the exception of old growth timber, construction and demolition-derived wood and whole trees that are not part of a closed-loop biomass system, cleared solely for the purpose of energy production, unsegregated solid waste, or post-consumer wastepaper:
(a) Mill residue;
(b) Slash;
(c) Brush;
(d) Yard waste;
(e) A waste pallet, crate, or dunnage;
(f) Agricultural sources, including tree crops, vineyard materials, grain, legumes, sugar, and other crop by products or residues; or
(g) Cofired biomass, subject to the condition under D.C. Official Code § 34-1433(f).

Law 22-257).

Renewable Generator – a generator that produces energy from a Tier One renewable source or Tier Tworenewable source.
Revenue-Grade Generation Meter – A meter used by a behind-the-meter generator or CREF that measures the generated electricity at the AC output of an inverter, is capable of recording the cumulative kilowatt-hours that the generator produces which meets the latest American National Standards Institute (ANSI) C-12.20 standard including an accuracy deviation no greater than +/- 0.5%, and that easily displays all collected data and retains lifetime production even in the event of a power outage.
