1. (a) In any rate proceeding, any utility and/or municipality claiming reimbursement for its rate case expenses pursuant to Texas Utilities Code, §103.022(b), shall have the burden to prove the reasonableness of such rate case expenses by a preponderance of the evidence. Each gas utility and/or municipality shall detail and itemize all rate case expenses and allocations and shall provide evidence showing the reasonableness of the cost of all professional services, including but not limited to:

   1. (1) the amount of work done;
   2. (2) the time and labor required to accomplish the work;
   3. (3) the nature, extent, and difficulty of the work done;
   4. (4) the originality of the work;
   5. (5) the charges by others for work of the same or similar nature; and
   6. (6) any other factors taken into account in setting the amount of the compensation.
2. (b) In determining the reasonableness of the rate case expenses, the Commission shall consider all relevant factors including but not limited to those set out previously, and shall also consider whether the request for a rate change was warranted, whether there was duplication of services or testimony, whether the work was relevant and reasonably necessary to the proceeding, and whether the complexity and expense of the work was commensurate with both the complexity of the issues in the proceeding and the amount of the increase sought as well as the amount of any increase granted.
