The following schedule is applicable to the Integrated
					 Resource Plan reporting requirements set forth herein:
1. Within thirty (30) days of the
				  Commission's final approval of this Rule, each electric utility subject to the
				  IRP provisions of this Rule shall file a "Notice of IRP Cycle" in a new
				  Commission docket. The filing of such Notice shall initiate the IRP planning
				  and reporting cycle described herein. Interested parties may move to intervene
				  in a specific electric utility's IRP docket in accordance with Rule 6-121 of
				  the Commission Rules of Practice and Procedure. Interested parties may also
				  proceed with the execution of utility nondisclosure agreements in accordance
				  with Section 108 of this Rule at any time after the filing of a Notice of IRP
				  Cycle.
2. Within thirty (30) days of
				  filing a Notice of IRP Cycle, each electric utility subject to the IRP
				  provisions of this Rule shall notice and conduct an initial public workshop for
				  interested parties to take place in the Commission's hearing room in Jackson,
				  Mississippi. The purpose of the initial workshop is for the electric utility
				  and interested parties to exchange pertinent information concerning the IRP
				  process, such as resource options, planning assumptions and inputs that may be
				  used in the development of a utility's Integrated Resource Plan. Any interested
				  party that attends the public workshop may also provide written feedback to the
				  electric utility and the Commission within twenty-five (25) days following the
				  workshop.
3. No later than
				  forty-five (45) days prior to an electric utility filing its Integrated
				  Resource Plan, the electric utility shall notice and conduct a technical
				  conference for those interested parties that have executed a nondisclosure
				  agreement in accordance with Section 108 of this Rule. The technical conference
				  shall also take place in the Commission's hearing room in Jackson, Mississippi.
				  The purpose of the technical conference is for the electric utility to provide
				  an overview of the process, planning assumptions and inputs ultimately used to
				  develop its Integrated Resource Plan, and to answer questions related thereto.
				  Interested parties that participate in the technical conference may provide
				  additional written feedback to the utility and the Commission within
				  twenty-five (25) days following the technical conference.
4. Electric Utilities subject to the
				  provisions of this Rule shall file their first Integrated Resource Plan in
				  their respective IRP dockets no later than twelve (12) months after issuance of
				  the Commission's Final Order Approving this Rule. Each successive Integrated
				  Resource Plan shall be filed in the same IRP docket no later than three (3)
				  years thereafter. Each successive IRP cycle shall begin with the filing of a
				  Notice of IRP Cycle and shall follow the schedule provided herein.
5. The filed Integrated Resource Plan shall
				  include as a confidential appendix a set of work papers showing the key inputs
				  used by the utility in developing the Plan. Interested parties may obtain
				  copies of these work papers in accordance with the Confidentiality provisions
				  of Section 108 of this Rule.
6.
				  Within sixty (60) days of a utility filing its Integrated Resource Plan, any
				  interested party may file comments addressing the Integrated Resource Plan. The
				  Mississippi Public Utilities Staff ("Public Utilities Staff" or "Staff") shall
				  have eighty (80) days from the IRP filing date to file any comments on the
				  Plan. Initial Data Requests may be served upon the utility within thirty (30)
				  days of the utility filling its Integrated Resource Plan.
7. Utilities may provide a response to any
				  such comments no later than one hundred (100) days after the filing of its
				  Plan.
8. The Commission shall
				  review the Integrated Resource Plan and note any deficiencies within one
				  hundred twenty (120) days after its submittal by the utility. The Public
				  Utilities Staff shall assist the Commission with its review. If the Staff
				  believes the use of consultants is necessary or helpful in its review of any
				  Integrated Resource Plan, the utility shall be required to pay for the cost of
				  such consultants and allowed to recover said costs in rates.
9. The Commission may require the utility to
				  re-evaluate and resubmit its Integrated Resource Plan for the current planning
				  cycle to address any concerns raised in the comments or expressed by the Staff
				  or Commission.
10. Absent
				  deficiencies, the Integrated Resource Plan review is concluded one hundred
				  twenty (120) days after submittal of the Integrated Resource Plan by the
				  utility.
