This subchapter provides a number of tools to an electric utility to mitigate stranded costs. Each electric utility that was reported by the commission to have positive "excess costs over market" (ECOM), denoted as the "base case" for the amount of stranded costs before full retail competition in 2002 with respect to its Texas jurisdiction, in the April 1998 Report to the Texas Senate Interim Committee on Electric Utility Restructuring entitled "Potentially Strandable Investment (ECOM) Report: 1998 Update," must use these tools to reduce the net book value of, otherwise referred to as "accelerate" the cost recovery of, its stranded costs each year. Any positive difference under the report required by Section 39.257(b) shall be applied to the net book value of generation assets.
