Nothing in subsections (b)(1), (b)(2), and (b)(3) of this section shall affect any existing or future methodology employed by a Transmission Organization for allocating or auctioning transmission rights if such Transmission Organization was authorized by the Commission to allocate or auction financial transmission rights on its system as of January 1, 2005, and the Commission determines that any future allocation or auction is just, reasonable and not unduly discriminatory or preferential, provided, however, that if such a Transmission Organization never allocated financial transmission rights on its system that pertained to a period before January 1, 2005, with respect to any application by such Transmission Organization that would change its methodology the Commission shall exercise its authority in a manner consistent with the  chapter and that takes into account the policies expressed in subsections (b)(1), (b)(2), and (b)(3) as applied to firm transmission rights held by a load-serving entity as of January 1, 2005, to the extent the associated generation ownership or power purchase arrangements remain in effect.
The Commission may exercise authority under this chapter to make transmission rights not used to meet an obligation covered by subsection (b) available to other entities in a manner determined by the Commission to be just, reasonable, and not unduly discriminatory or preferential.
Nothing in this section shall provide a basis for abrogating any contract or service agreement for firm transmission service or rights in effect as of August 8, 2005. If an ISO in the Western Interconnection had allocated financial transmission rights prior to August 8, 2005, but had not done so with respect to one or more load-serving entities’ firm transmission rights held under contracts to which the preceding sentence applies (or held by reason of ownership or future ownership of transmission facilities), such load-serving entities may not be required, without their consent, to convert such firm transmission rights to tradable or financial rights, except where the load-serving entity has voluntarily joined the ISO as a participating transmission owner (or its successor) in accordance with the ISO tariff.
The Commission shall ensure that any entity described in section 824(f) of this title that owns transmission facilities used predominately to support its own water pumping facilities shall have, with respect to the facilities, protections for transmission service comparable to those provided to load-serving entities pursuant to this section.
This section shall not apply within the area referred to in section 824k(k)(2)(A) of this title.
This section does not authorize the Commission to take any action not otherwise within the jurisdiction of the Commission.
An entity that to the extent required to meet its service obligations exercises rights described in subsection (b) shall not be considered by such action as engaging in undue discrimination or preference under this chapter.
