The purpose of this subchapter is to enable utilities to use securitization financing to recover regulatory assets, all other amounts determined under § 39.262, and any amounts being recovered under a competition transition charge determined as a result of the proceedings under Sections 39.201 and 39.262. This type of debt will lower the carrying costs of the assets relative to the costs that would be incurred using conventional utility financing methods. The proceeds of the transition bonds shall be used solely for the purposes of reducing the amount of recoverable regulatory assets and other amounts, as determined by the commission in accordance with this chapter, through the refinancing or retirement of utility debt or equity. The commission shall ensure that securitization provides tangible and quantifiable benefits to ratepayers, greater than would have been achieved absent the issuance of transition bonds. The commission shall ensure that the structuring and pricing of the transition bonds result in the lowest transition bond charges consistent with market conditions and the terms of the financing order. The amount securitized may not exceed the present value of the revenue requirement over the life of the proposed transition bond associated with the regulatory assets or other amounts sought to be securitized. The present value calculation shall use a discount rate equal to the proposed interest rate on the transition bonds.
