Section 310 - Investigation of proposed changes in rates of public utilities1.Investigation of proposed rate changes. When the commission receives notice of any change proposed to be made in a schedule of rates filed with the commission under the provisions of law, it may at any time before the effective date of the change, either upon complaint or upon its own motion and after reasonable notice, hold a public hearing and make investigation as to the propriety of the proposed change. The hearing shall be held in accordance with section 1304. At any such hearing involving any change, the burden of proof to show that the change is just and reasonable is upon the public utility. After a hearing and investigation, the commission may make an order with reference to any new rate, joint rate, rental, toll, classification, charge, term, condition or form of contract or agreement proposed as would be proper in a proceeding initiated upon complaint or upon motion of the commission in any rate investigation. In implementing the order, the commission shall assure rate design stability. [1987, c. 141, Pt. A, §6(NEW).]
