Primary energy source

Primary energy source means the fuel or fuels used by any existing or new electric powerplant except:
(1) Minimum amounts of fuel required for unit ignition, startup, testing, flame stabilization, and control uses. OFE has determined that, unless need for a greater amount is demonstrated, twenty-five (25) percent of the total annual Btu heat input of a unit shall be automatically excluded under this paragraph.
(2) Minimum amounts of fuel required to alleviate or prevent:
(i) Unanticipated equipment outages as defined in § 501.191 of these regulations; and
(ii) Emergencies directly affecting the public health, safety, or welfare that would result from electric power outages as defined in § 501.191 of these regulations.
(1) Any fuel excluded under the provisions of paragraph (1) of this definition is in addition to any fuel authorized to be used in any order granting a fuel mixtures exemption under parts 503 and 504 of these rules. The exclusion of fuel under paragraph (1), together with the authority for such additive treatment, shall apply to any jurisdictional facility, regardless of whether or not it had received an order granting an exemption as of the date these rules are promulgated.
(2) If an auxiliary unit to an electric powerplant consumes fuel only for the auxiliary functions of unit ignition, startup, testing, flame stabilization, and other control uses, its use of minimum amounts of natural gas or petroleum is not prohibited by FUA. The measurement of such minimum amounts of fuel is discussed in Associated Electric Cooperative, et al., Interpretation 1980-42 [45 FR 82572, Dec. 15, 1980].
