NYISO Tariffs --> Market Administration and Control Area Services Tariff (MST) --> 23 MST Att H - ISO Market Power Mitigation Measures --> 23.5 MST Att H Other Mitigation Measures
To facilitate the application of the Real-Time mitigation measures specified in this Attachment H for Constrained Areas, all Generators located in a Constrained Area that are capable of doing so shall respond to RTD Base Point Signals, unless such a Generator is subject to contractual obligations in existence prior to June 1, 2002 that would preclude such operation.
23.5.2.1If an In-City Generator is scheduled in any hour in the Day-Ahead Market to meet the reliability needs of a local system, the ISO will set the In-City Generator’s Start-Up Bid to the lower of the Bid or the applicable reference level, which may include a Start-Up reference level calculated in accordance with Section 23.3.1.4.4.3 of these Mitigation Measures. In each hour an In-City Generator is scheduled in the Day-Ahead Market to meet the reliability needs of a local system, the ISO will set the In-City Generator’s Minimum Generation Bid to the lower of the Bid or the applicable reference level.
23.5.3.1Local reliability rules require that specified amounts of Spinning Reserves be provided by In-City Generators or Aggregations. The Spinning Reserve-capable portion of each Generator or Aggregation located in New York City must be made available to the ISO for purposes of meeting the New York City Spinning Reserve requirement.
23.5.3.2The market power mitigation measures applicable to Spinning Reserves will be implemented when the ISO’s least-cost dispatch requires that one or more of the Generators or Aggregations located in New York City be committed to meet the In-City Spinning Reserve requirement. For any day that an In-City Generator or Aggregation is committed to meet the In-City Spinning Reserve requirement under circumstances where the Generator or Aggregation would not otherwise have been committed under the ISO’s least-cost dispatch, the market power mitigation measures applicable to unit commitments, as described in Section 23.5.2, would apply.
In addition to any mitigation measures specified above, the ISO shall administer, and apply when appropriate in accordance with their terms, such other mitigation measures as it may be directed to implement by order of the FERC.
