Subject 515-7-11 CAPACITY SUPPLY PLANS

Rule 515-7-11-.01 Definitions

As used in this Utility Rule 515-7-11, the following terms have the following definitions:

(a) Act: The Natural Gas Competition and Deregulation Act as provided for in O.C.G.A. § 46-4-150et seq.
(b) Ancillary Service: A service that is ancillary to the receipt or delivery of natural gas, including without limitation, storage, balancing, peaking, and customer service.
(c) Capacity Supply Plan: The plan of the Electing Distribution Company for obtaining the interstate capacity assets necessary to make gas available on the EDC's system for firm distribution service to retail customers. Such a plan shall:
(i) Specify the range of the requirements to be supplied by interstate capacity assets;
(ii) Describe the array of interstate capacity assets selected by the EDC to meet such requirements;
(iii) Describe the criteria of the EDC for entering into contracts under such array of interstate capacity assets from time to time to meet such requirements; provided however, that a capacity supply plan approved or adopted by the Commission shall not prescribe the individual contracts to be executed by the electing distribution company in order to implement such plan; and
(iv) Specify the portion of the interstate capacity assets that must be retained and utilized by the EDC in order to manage and operate its system.
(d) Commission: The Georgia Public Service Commission.
(e) Commodity Sales Service: The sale of natural gas exclusive of any distribution or ancillary service.
(f) Distribution Service: The delivery of natural gas by and through the intrastate instrumentalities and facilities of a gas company or of a marketer certificated pursuant to O.C.G.A. § 46-4-153, regardless of the party having title to the natural gas.
(g) Electing Distribution Company: A gas company that elects to become subject to the provisions of the Act and satisfies the requirements of O.C.G.A. § 46-4-154.
(h) Firm Customer: A customer who purchases gas from a certified marketer on a firm basis that ordinarily is not subject to interruption or curtailment.
(i) Person: Any corporation, whether public or private; company; individual; firm; partnership; or association.
(j) Retail Customer: A person who purchases commodity sales service or distribution service and such purchase is not for the purpose of resale.

Rule 515-7-11-.02 Commission Authority and Scope of Provisions

(a) Consistent with Official Code of Georgia Annotated (O.C.G.A.) §§ 46-4-155(e), each Electing Distribution Company shall be required to develop and file for the Commission's review and approval Capacity Supply Plans, as described by the regulations in this Rule. These regulations establish guidelines for the development and submission of Capacity Supply Plan, including filing requirements enabling Commission oversight, review and monitoring, the establishment of hearing procedures, and provide for the periodic review of each EDC's Capacity Supply Plan. Interim monitoring is established through the reporting requirements. These regulations also provide for Capacity Supply Plan amendments.
(b) In the event of any conflict between the provisions of this Rule and applicable provisions of the Official Code of Georgia Annotated, including O.C.G.A. § 46-4-155 as it may be amended from time to time, the applicable provisions of the O.C.G.A. shall take precedence. Any such conflict as to one provision of this rule shall not, however, void or nullify any remaining provisions of this rule.

Rule 515-7-11-.03 Hearing Procedures

(a) The following hearing procedure shall be used for Capacity Supply Plans:
1. Not less than ten days after any filing by an EDC of its Capacity Supply Plan for the following three years, the Commission shall conduct a public hearing on such filing. The EDC's testimony shall be under oath and shall, with any corrections thereto, constitute the EDC's affirmative case, respectively. At any such hearing, the burden of proof to show that the proposed Capacity Supply Plan is appropriate shall be upon the EDC.
2. The provisions of law relating to parties, intervention, and discovery in proceedings before the Commission shall apply with respect to such proceedings.
3. Following such a hearing, the Commission shall issue an order approving the Capacity Supply Plan filed by the EDC or adopting a Capacity Supply Plan for the EDC that the Commission deems appropriate.
4. If, for any reason, the Commission does not issue an order by the 45th day after the EDC's filing which either approves the Capacity Supply Plan filed by the EDC or adopts a different Capacity Supply Plan for the EDC, the Capacity Supply Plan proposed by the EDC shall thereupon be deemed approved by operation of law.
