After a late amendment, the Planning Advisory Committee last week approved a document describing the process for reviewing Business Practices Manual changes.

PAC Chair Bob McKee, with consent from the sector representatives, asked that a single sentence be added to allow an additional stakeholder review of any BPM changes made during MISO legal and compliance review. Previously, stakeholders had no procedure for getting a final look at changes made by MISO’s legal department at the end of the process.

Matthew Tackett, a MISO principal adviser, agreed to the addition.

Based on stakeholder input since December, MISO also included a statement to the language to explain how to update the document itself. MISO has worked on the updated process since November. (See “Business Practices Manuals Review Process Gets a Final Look,” MISO Planning Advisory Committee Briefs.)

However, MISO would not commit to allowing the comment period for new BPM language to extend over two consecutive meetings, as stakeholders advocated. “MISO will endeavor to provide additional time for comments… However, there may be times when BPM changes must be expedited, and under these situations, less time may be available for comments,” the RTO wrote.

MISO staff said it would post the finalized BPM process language on the MISO website under the planning tab, but the document will not be considered an official MISO governing document. MISO said it would be “posted for informational purposes only to codify the general process used by the Planning Advisory Committee and reporting committees regarding the review of BPM changes.”

Attachment Y Adjustments Put on Hold for a Month

Changes to Attachment Y of MISO’s Tariff, which deals with the planning process behind system support resources, will be put on hold for a month, said Neil Shah, an adviser on seams administration.

Shah said MISO didn’t receive enough substantive comments on the proposed changes. As a result, MISO is now planning to file Tariff language by the end of March instead of the end of February. Shah said staff wants to discuss the changes at the March 1 Market Subcommittee meeting before filing.

MISO is proposing that all generation resources planning to suspend or retire, including pseudo-tied units, black start units and generators on a forced outage, be required to submit Attachment Y notices to MISO.
