  2. Additional changes are required to Section III.13 to support Capacity Zone Modeling changes • Allow for bidirectional trading of CSO Bilaterals between Capacity Zones • Document all Ownership Shares of Pool-Planned Units • Conform Section III.13 of Market Rule 1 to the Capacity Zone Modeling changes proposed in Section III.12

  3. Bidirectional trading of CSO Bilaterals • ISO reviewed the participant proposal discussed at the December MC to allow for increased flexibility related to CSO Bilateral trading • The ISO believes this can be implemented in time for the CSO Bilateral Period for CCP 2015-2016 ARA 3 • Modifications to Section III.13.5 of Market Rule 1 are required to allow CSO Bilaterals in both directions of a modeled constraint and ensure that the LSR/MCL continue to be met when reviewing transactions • CSO Bilaterals will continue to be reviewed following the same approach as today and will be accepted/rejected based upon their confirmation timestamp

  4. Document Ownership Shares of Pool-Planned Units • The information within Section III.13.7.3.3.6. of Market Rule 1 reflects only the ownership shares in Pool-Planned Units within the existing Capacity Zones • The ISO is planning to include all ownership shares for Pool-Planned Units • In the event a new import-constrained Capacity Zone is formed the specifically allocated CTR rules will properly include the ownership of the Pool-Planned Units

  5. Additional conforming changes are required to the market rule • Update Section III.13 of Market Rule 1 to properly state Capacity Zone in place of the current Load Zone language

  6. Proposal Summary and Schedule • Allow for bidirectional trading of CSO Bilaterals between Capacity Zones • Document Ownership Shares of Pool-Planned Units • Conform Section III.13 to the Capacity Zone Modeling changes proposed in Section III.12 • The expected effective date of these changes is December 1, 2014
