ISO’s Right to Dispatch Sample Clauses
The "ISO’s Right to Dispatch" clause grants the Independent System Operator (ISO) the authority to control and direct the operation of power generation and transmission resources within its jurisdiction. In practice, this means the ISO can instruct generators when to increase or decrease output, or require certain facilities to start up or shut down, in order to maintain grid reliability and balance supply with demand. This clause is essential for ensuring the safe and efficient operation of the electrical grid, as it centralizes operational decisions and helps prevent system instability or blackouts.
ISO’s Right to Dispatch. (a) Subject to the limitations set forth in this Agreement, ISO shall direct dispatch of a Unit by delivering a Dispatch Notice to Owner’s Scheduling Coordinator in accordance with the ISO Tariff.
(b) Dispatch Notices for Energy, other than Energy associated with Ancillary Services, shall be issued solely for purposes of meeting local reliability needs or managing intra-zonal congestion. For purposes of dispatching Energy, local reliability needs do not include Energy required to manage inter-zonal congestion. ISO shall issue Dispatch Notices to meet local reliability needs or manage intra- zonal congestion whenever market bids cannot be used to meet those needs or manage such congestion or such market bids cannot be used to meet those needs or manage such congestion without taking a bid out of merit order or requiring ISO to decrement another supplier’s schedule to accommodate the unit which provided the bid. ISO may not issue a Dispatch Notice to fill a need for imbalance energy.
(c) Except as needed for black start or voltage support required to meet local reliability needs, to meet operating criteria associated with Potrero and Hunters Point power plants, or as outlined below, ISO may issue Dispatch Notices for Ancillary Services only if the available bids in Ancillary Service capacity markets do not provide sufficient capacity to meet ISO’s requirements.
(i) The ISO may elect to procure from the day-ahead market less than the amount of an Ancillary Service that it knows to be needed as of the close of that market and instead procure the balance from the hour-ahead markets. Before doing so, the ISO must communicate to all Scheduling Coordinators its intention to procure a portion of its needs from the hour- ahead market. Such communication shall state the projected hourly megawatt amounts of each Ancillary Service it has shifted from day-ahead to hour-ahead procurement. Amounts shifted under this provision are not subject to the Bid Sufficiency Test described below.
(ii) If, after the close of the day-ahead market for a Trading Day, but before ISO issues final hour-ahead schedules for the first hour of the Trading Day, ISO determines it needs additional Ancillary Services for the Trading Day, ISO shall use unused, available day-ahead market bids for Ancillary Services for the Trading Day in merit order (and in the appropriate zone, if ISO is procuring Ancillary Services on a zonal basis) to fill its Ancillary Services needs before issuing a Dispatch No...
ISO’s Right to Dispatch. Subject to the limitations set forth in this Agreement, ISO shall have the right to direct the dispatch of Contracted Capability from the Project up to five hundred (500) hours per Year during Peak Hours of Peak Periods by issuing Dispatch Notices and/or Incremental Dispatch Notices to Owner’s Scheduling Coordinator. Each Requested Operation Period under a Dispatch Notice and/or an Incremental Dispatch Notice for a new Requested Operation Period issued under Section 4.2 shall be of a duration of not less than four (4) consecutive hours.
