     69-8-403. Commission authority -- rulemaking authority. (1) Beginning on the effective date of a commission order regarding a public utility's transition plan, the commission shall regulate the public utility's retail transmission and distribution services within the state of Montana, as provided in this chapter, and may not regulate the price of electricity supply except as electricity supply may be procured as provided in this section:
     (a) by one or more default suppliers for those customers not being served by a competitive supplier; or
     (b) by the distribution function of a public utility for those customers that are not being served by a competitive electricity supplier as provided by commission rules. During the transition period, those procurements may include a cost-based contract from a supply affiliate or an unregulated division.
     (2) The commission shall decide if there is workable competition in the electricity supply market by determining whether competition is sufficient to inhibit monopoly pricing or anticompetitive price leadership. In reaching a decision, the commission may not rely solely on market share estimates.
     (3) The commission shall license electricity suppliers and enforce licensing provisions pursuant to 69-8-404.
     (4) The commission shall promulgate rules that identify the licensees and ensure that the offered electricity supply is provided as offered and is adequate in terms of quality, safety, and reliability.
     (5) The commission shall establish just and reasonable rates through established ratemaking principles for public utility distribution and transmission services and shall regulate these services. The commission may approve rates and charges for electricity distribution and transmission services based on alternative forms of ratemaking such as performance-based ratemaking, on a demonstration by the public utility that the alternative method complies with this chapter, and on the public utility's transition plan.
     (6) The commission shall certify that a cooperative utility has adopted a transition plan that complies with this chapter. A cooperative utility's transition plan is considered certified 60 days after the cooperative utility files for certification.
     (7) The commission shall promulgate rules that protect consumers, distribution services providers, and electricity suppliers from anticompetitive and abusive practices.
     (8) The commission shall establish electricity supply rates for individual customer classes, which may vary based on cost factors associated with classifications of service or customers and any other reasonable consideration. Collectively, the individual electricity supply rates must reflect the full level of electricity supply costs that the default supplier incurs on behalf of its customers.
     (9) Until the commission has determined that workable competition has developed for small customers, a default supplier's obligation to serve remains.
     (10) In addition to promulgating rules expressly provided for in this chapter, the commission may promulgate any other rules necessary to carry out the provision of this chapter.
     (11) This chapter does not give the commission the authority to:
     (a) regulate cooperative utilities in any manner other than reviewing certification filings for compliance with this chapter; or
     (b) compel any change to a cooperative utility's certification filing made pursuant to this chapter.
