Review of completed construction; costs exceeding estimated and approved costs

Sec. 8. A public utility may elect to forgo any commission review of the construction and cost until completion of the clean coal technology system. If the commission has annually approved the continuing need for the project under section 5 of this chapter, and to the extent the public utility seeks to add to the rate base an amount that does not exceed that filed under section 4(a) of this chapter, the inclusion of that amount may be challenged only on the basis of inadequate quality controls. However, inclusion of costs in excess of those approved by the commission under section 4(b)(2) of this chapter is not permitted unless the public utility shows those costs to be necessary and prudent.
