RELATING TO IMPLEMENTATION OF THE INTEGRATED MARKETPLACE

Whitepaper from CBASC

3. RELATIONSHIP TO THE MEMBERSHIP AGREEMENT

3.1 MEMBERSHIP AGREEMENT. Attachment A to the Membership Agreement sets forth a division of responsibilities in accordance with the NERC functional model. This Agreement is intended to be a specific delineation of functions between SPP Balancing Authority (SPP BA) and the SPP Member who are NERC Registered Entities. All conflicts between Attachment A and this Agreement are to be resolved in favor of this Agreement.

3.2 SPP BA is responsible for the actions and processes outlined in this agreement. It is acknowledged that there are specific Balancing Authority tasks that the SPP Balancing Authority cannot perform without specific of actions of SPP Members who are also NERC Registered Entities. These actions relate specifically to area tie line metering and frequency devices owned and maintained by SPP Members having tie lines with Balancing Authorities adjacent to the SPP Balancing Authority. Those specific responsibilities are listed below. (Note: tie lines and meter responsibilities between SPP TOP that are internal to the Integrated Marketplace are specified in the Integrated Marketplace Protocols and are not discusses in this agreement)

3.2.1 Each TOP shall provide all Tie Line flows with Adjacent Balancing Authority Areas to the SPP Balancing Authority for inclusion in the SPP BAA ACE calculation in a manner and frequency mutually agreed. (Reference BAL-005 R12)

3.2.2 Each TOP share a tie with an adjacent BA shall ensure Tie Line MW metering is tele-metered to both the SPP BAA control centers and the control center for the adjacent BA and that it emanates from a common, agreed-upon source using common primary metering equipment. TOPs shall ensure that megawatt-hour data is tele-metered or reported at the end of each hour. (Reference BAL-005 R12.1)

3.2.3 Each TOP shall ensure the power flow and that are utilized for calculating the SPP Balancing Authority performance or that are transmitted for Regulation Service are not filtered prior to transmission, except for the Anti-aliasing Filters of Tie Lines. (Reference BAL-005 R12.2)

3.2.4 Each SPP TOP shall install common metering equipment where Dynamic Schedules or Pseudo-Ties are implemented between the SPP BAA and other Balancing Authorities to deliver the output of Jointly Owned Units or to serve remote load. (Reference BAL-005 R12.3)

3.2.5 Each TOP sharing a tie with an adjacent BA shall perform hourly error checks using Tie Line megawatt-hour meters with common time synchronization to determine the accuracy of its control equipment. (Reference BAL-005 R13)

3.2.6 Each SPP TOP shall at least annually check and calibrate its time error and frequency devices used by the SPP BA to perform the BA function against a common reference. (Reference BAL-005 R17)

4. OPERATIONS

4.1 GENERAL. In carrying out obligations under this Agreement, the SPP BA and the SPP Member who are NERC Registered Entities shall (i) follow Good Utility Practice, (ii) comply with applicable policies, standards and requirements of NERC Standards and SPP Criteria and their successors, and (iii) follow applicable laws and regulations.

4.2 PURPOSE. The purpose of this Agreement is to delineate the responsibilities between SPP Balancing Authority and the SPP Member who are NERC Registered Entities as is necessary to allow the Integrated Marketplace to be implemented.

4.3 EFFECT OF TRANSFER OF RESPONSIBILITIES. To the extent that responsibilities and their associated tasks are transferred to the SPP Balancing Authority by this Agreement and, as applicable, upon approval by NERC and other applicable Regulatory entities, SPP here accepts the responsibilities, and the previously registered SPP member Balancing Authorities are no longer obligated to perform the tasks associated with the responsibilities that have been transferred except those contained in Article 3 to which those entities retain the responsibilities associated such as compliance with related NERC Standards and SPP Criteria.
