Setting an overall percentage of the utility’s expenses in a rate case that are not recoverable;(IV)

A source model showing all rate adjustments;(B)
Executable spreadsheets, also referred to as workpapers, with links and formulas intact;(C)
A test year based on a recently completed twelve-month period and for which actual costs and investments are analyzed; and(D)
Any other information or documentation, as determined by the commission; or(V)
Requiring a technical conference with intervening parties to address intervening parties’ questions and to provide the ability for interveners to analyze the utility’s assumptions and calculations supporting a rate case filing.(b)
Before the commission may determine that an investor-owned utility’s application to modify base rates is complete, the commission shall certify that, for comparison of test years and other purposes, the filing includes sufficient information, including a comprehensive cost and revenue requirement analysis based on actual, auditable, historical data, which analysis must be accompanied by appropriate workpapers and other supporting materials.(c)
Nothing in this section prohibits a utility from including multiple test years for analysis or consideration in a rate case filing, including inclusion of a future test year.(d)

For each of the ten years, the annual total amount of the rate, charge, fee, fare, toll, rental, or classification.(b)
