(a) The commission shall render a decision upon the record either granting or denying the application as filed or granting it upon such terms, conditions, or modifications of the financing, acquisition, operation, or maintenance of the property as the commission may deem appropriate. The commission may not grant a certificate for the financing, acquisition, operation, and maintenance of any property, either as proposed or as modified by the commission, unless it shall find and determine:

(1) The nature of the probable economic impact of the acquisition on the customers of the gas or electric public utility that owns the property and on the customers to be served by the municipality;

(2) That the method of financing the acquisition, either as proposed or as modified by the commission, represents an acceptable economic impact, considering economic conditions and the need for and cost to the municipality of additional gas or electric public utility services;

(3) That the acquisition of the properties, the gas or electric public utility functions to be performed, the operating procedures, the properties and equipment, and the use of the properties collectively provide reasonable assurance that the municipality will comply with all applicable laws and regulations and that the public health, safety, economy, and convenience will not be adversely affected;

(4) That the municipality is technically and financially qualified to acquire and operate the proposed properties in accordance with all applicable laws and regulations;

(5) That the issuance of the certificate will not be detrimental to the public health, safety, economy, and convenience; and

(6) That the acquisition will serve the public interest, convenience, and necessity.

(b) Any municipality which files an application for approval of the acquisition or purchase of any gas or electric utility property shall have the burden of proof with respect to every element of the application. The commission shall not approve any application for approval of the purchase or acquisition by any municipality of any property of a gas or electric public utility unless it shall be shown at the hearing upon the application for approval of the acquisition, by the clear preponderance of the evidence, that neither the gas or electric public utility nor the customers of the gas or electric public utility will be adversely affected by the proposed acquisition or purchase.
