; and (E) designate a representative as required under section 727(b). (3) Classification If a generator that produces useful thermal energy output elects to be classified as a qualified thermal facility pursuant to this subsection, such classification shall remain in effect unless the facility— (A) falls below a rated fuel-based capacity of 2,000,000 British thermal units on a higher heating value basis per hour; or (B) produces no useful thermal energy output over the previous calendar year. (c) Voluntary program participation as qualified cogeneration facility (1) In general A generator that simultaneously produces useful thermal energy output and electricity with a rated capacity of less than 2 megawatts may, in accordance with this subsection, elect to be classified as a qualified cogeneration facility for purposes of this title. (2) Qualification In order for a generator that simultaneously produces useful thermal energy output and electricity with a rated capacity of less than 2 megawatts to be classified as a qualified cogeneration facility, the facility shall— (A) submit a notification to the Administrator of the intention of the generator to elect to be classified as a qualified cogeneration facility; (B) receive approval of the classification from the Administrator; (C) report annually to the Administrator relevant information collected on type, quality, and quantity of fuel used for onsite useful thermal energy output production, the quantity of useful thermal energy output, and the quantity of associated greenhouse gas emissions under section 713
