(a) If, in an expedited hearing pursuant to the provisions of Chapter 13 of Title 50, the "Georgia Administrative Procedure Act":

(1) The commission determines for a specific delivery group, as to which the commission has issued an order pursuant to subsection (b) of Code Section 46-4-156, that the prices for natural gas paid by retail customers in such delivery group are not constrained by market forces and are significantly higher than such prices would be if they were constrained by market forces; or

(2) The commission determines for a specific delivery group, as to which the commission has not issued an order pursuant to subsection (b) of Code Section 46-4-156, that the prices charged by an electing distribution company to residential customers for commodity sales services, which prices have not been approved by the commission pursuant to Code Section 46-2-26.5, are generally not constrained by market forces and are significantly higher than such prices would be if they were constrained by market forces,

then the commission, on an emergency basis, may by order temporarily impose such directives on gas companies subject to its jurisdiction as are required to protect the interests of retail customers in such delivery group including but not limited to price regulations and the imposition upon the electing distribution company of the obligation to serve retail customers in such delivery group under the same or similar conditions to those under which such customers were served prior to customer assignment in such delivery group. In no event shall such emergency directives extend beyond the first day of July immediately following the next full annual session of the General Assembly after the imposition of such directives. In its order the commission shall provide for recovery of all costs reasonably incurred by the electing distribution company in complying with the directives. Any such directives shall be drawn as narrowly as possible to accomplish the purpose of protecting the public on an interim basis. No such directive shall impose any condition upon the electing distribution company which unreasonably burdens the company. Such directives shall be immediately reviewable in the Superior Court of Fulton County in the same manner and subject to the same procedures as the review of any other contested case under the provisions of Code Section 50-13-19. The provisions of this Code section shall not apply to a delivery group for which customer assignment occurred more than four years prior to the date of notice of the expedited hearing.

(b) If, in an expedited hearing pursuant to the provisions of Chapter 13 of Title 50, the "Georgia Administrative Procedure Act," the commission determines that market conditions are no longer competitive, then the commission, on an emergency basis, may by order temporarily impose such directives on marketers as are required to protect the interests of retail customers in the state, including, but not limited to, price regulations on the marketers. For purposes of this subsection, market conditions shall be considered competitive as long as there are at least three marketers soliciting and providing distribution services to residential and small business customers in this state; provided, however, that, in any case where there are three or less marketers soliciting and providing distribution services to residential and small business customers in this state, market conditions shall not be considered competitive if the commission upon clear and convincing evidence determines that as a result of collusion among such marketers, prices for natural gas paid by retail customers are not being adequately constrained by market forces and are significantly higher than such prices would be if they were constrained by market forces. In no event shall such emergency directives extend beyond the first day of July immediately following the next full annual session of the General Assembly after the imposition of such directives. Any such directives shall be drawn as narrowly as possible to accomplish the purpose of protecting the public on an interim basis. Such directives shall be immediately reviewable in the Superior Court of Fulton County in the same manner and subject to the same procedures as the review of any other contested case under the provisions of Code Section 50-13-19.
