Not later than ninety (90) days after the date of the commission’s order under this subsection, the public utility shall file for approval with the commission a plan to comply with the commission’s order. The public utility’s plan may include:

(1) a request for a certificate of public convenience and necessity under this chapter; or

(B) total fall UCAP that public utilities should be authorized to acquire from capacity markets under subsection (g)(4)(B).

     (t) The commission may adopt rules under IC 4-22-2 to implement this section.
