Haw. Code R. § 6-74-6 - Criteria for qualifying cogeneration facilities
(a) For
any topping-cycle cogeneration facility, the useful thermal energy output of
the facility during any calendar year period, shall be not less than five per
cent of the total energy output.
(b) For any topping-cycle cogeneration
facility for which any of the energy input is natural gas or oil, and the
installation of which began on or after March 13, 1980, the useful power output
of the facility plus one-half the useful thermal energy output, during any
calendar year period, shall:
(1) Subject to
paragraph (2), be not less than 42.5 per cent of the total energy input of
natural gas and oil to the facility; or
(2) If the useful thermal energy output is
less than fifteen per cent of the total energy output of the facility, be not
less than forty-five per cent of the total energy input of natural gas and oil
to the facility.
(c) For
any topping-cycle cogeneration facility not subject to subsection (b), there is
no efficiency standard.
(d) For any
bottoming-cycle cogeneration facility for which any of the energy input as
supplementary firing is natural gas or oil, and the installation of which began
on or after March 13, 1980, the useful power output of the facility during any
calendar year period, shall be not less than forty-five per cent of the energy
input of natural gas and oil for supplementary firing. For all other
bottoming-cycle cogeneration facilities, there is no efficiency
standard.
(e) The commission may
waive any of the requirements of this section upon a showing that the facility
will produce significant energy savings.
