If unreasonable profits have been made in any such transactions, evaluations of such materials and services may be reduced accordingly.
   7. Employ and fix the compensation of rate experts, engineers, and all other expert held and assistance for rate increase application hearings, investigations, and proceedings relating to utilities, subject to Subsection (2) (h) and (2) (j).
