(a) On or after October 1, 1999, upon complaint or upon its own motion, for good cause shown, the Commission may conduct an investigation of the retail electric supply service market and whether the function of that market is being adversely affected by market power arising from the ownership or control of facilities and equipment used to provide electric supply service.
(b) If, as a result of an investigation conducted under this section, the Commission has reason to believe that market power in the relevant market under the Commission’s jurisdiction is preventing retail electric customers in the State from obtaining the benefits of retail competition, the Commission may take remedial actions to mitigate the impact of such activities, including ordering divestiture. However, in the case of divestiture, the Commission may only order divestiture of generating assets of a public utility and only in an extreme situation and as a last resort measure.
