• New tariff language for NCPC Credits will completely replace the current MR-1 Appendix F sections III.F.1 and III.F.2
• Section III.F.3 (NCPC Cost Allocation) is untouched
• Several new defined terms are added to Section I.2.2– Commitment Period– Economic Dispatch Point (EDP)– Effective Offer
New Section III.F.1 - General
• Concepts that apply generally in the determination of NCPC Creditsa) Effective Offersb) Treatment of Self-Schedulesc) Treatment of Minimum Run Time Changes in a Subsequent
Operating Dayd) Supply Offers Applicable When Min Run Time Carries into Second
Operating Daye) Supply Offers Applicable When Committed Prior to Day-Ahead
Energy Marketf) Eligibility for NCPC Credits When Performing Auditsg) Coordinated External Transactions are Not Eligible for NCPC
