Sec. 6. If a public utility cancels the implementation of the technology as a result of the modification or revocation of a certificate by the commission under section 5 of this chapter, the public utility may recover the amount of its investment in the technology, along with a reasonable return on the unamortized balance. The utility may not recover on amounts expended in excess of the cost estimates approved by the commission under section 4 of this chapter unless the utility can prove to the commission that those expenditures were necessary and prudent. The recovery must be made over a reasonable period of time through rates charged by the public utility. A recovery may not be made if there was fraud, concealment, or gross mismanagement on the part of the public utility.
