Additional clean-up changes to support implementation
Energy Market Offer Flexibility:Conforming Rules
2
Additional changes are required to support the Energy Market Offer Flexibility and NCPC Payments projects
• The ISO has identified conforming changes to the Forward Reserve Market and the Regulation Market
• The ISO is proposing to remove obsolete provisions and references and has identified some instances of defined terms which are not capitalized
• Additional changes are required to Market Rule 1, Appendix A and Appendix F
3
Forward Reserve Market
• Modify the deadline for submitting offers above the Forward Reserve Threshold Price from the close of the Re-Offer Period to no later than 30 minutes prior to the start of the operating hour.
4
Regulation Market
• Modify the Regulation Market rules to consider a scenario introduced by the Energy Market Offer Flexibility functionality that permits a resource to self-schedule intra hour. – A unit selected for regulation that updates its offer through an intra
hour self-schedule will have its energy opportunity cost set to zero.
• The ISO is continuing to evaluate the impacts of negative energy offers on the Regulation Market design scheduled to be implemented in May 2014.
5
Additional Changes
• Remove transition provision added to provide flexibility during the interim between the current market and the hourly markets implementation. These include:– The Appendix A Cost Recovery Provisions added to the tariff by the
ISO’s August 13, 2014 filing with the Commission– The Dual-Fuel Switching Provisions added to the tariff by the ISO’s
December 19, 2013 filing with the Commission•
6
Additional Changes (continued)
• Capitalize and add newly defined terms, revise terms with obsolete references and delete terms that are no longer defined.
• Remove language that is no longer required as it has been superseded by the Energy Market Offer Flexibility and NCPC Payments tariff provisions. These include:– Obsolete cancelled start credit– Obsolete references to NCPC– A participant obligation to provide non-binding forecasts of supply
offers.
7
Additional Changes (continued)
• Changes to Appendix A– Correct a typographical error; Section III.A.7.2.2.(d)(iii) should be labeled as
III.A.7.2.2(e) to indicate that a cost-based Reference Level will be used when a fuel price is submitted pursuant to III.A.3.4.
– Clarify, in the newly labeled Section III.A.7.2.2(e), that a cost-based Reference Level will apply for the Operating Day or remainder of the Operating Day.
• Delete the recently added III.F.1(c) provision for Treatment of Minimum Run Time Changes in Subsequent Operating Day that is unnecessary under the Energy Market Offer Flexibility implementation. – A resource commitment to operate across an operating day boundary will
continue through the hours of the original commitment decision duration in the subsequent day, irrespective of a change to its Minimum Run Time .

Additional changes are required to support the Energy Market Offer Flexibility and NCPC Payments projects
• The ISO is continuing to assess whether additional changes will be required to support the implementation.
• Proposed Markets Committee Schedule:– February MC – introduce additional changes– April MC – draft tariff language plus any newly identified changes– May MC (June, if substantial new items are identified) – request vote
