(3) the electric utility has a separate division within the electric utility for its generation business activities.
(c-1) A separate division described by Subsection (c)(3) is subject to Subsection (d) and, for the purposes of this chapter, is considered a separate affiliated power generation company and a competitive affiliate.
(d) Each electric utility shall unbundle under this section in a manner that provides for a separation of personnel, information flow, functions, and operations, consistent with § 39.157(d).
(e) Each electric utility shall file with the commission a plan to implement this section by January 10, 2000.
