Participation of De-Listed MWs in the Real Time Energy Market (RTEM): The Settlement Agreement at Article IV.B.4 indicates that de-listed resources not offered and "accepted" in the DAEM must be self-scheduled to participate in the RTEM.
- Does "accepted" mean the de-listed MWs were offered into the DAEM regardless of whether any of the MWs of the unit (including the "listed" portion) were scheduled in the DAEM? If not, please explain how RTEM participation by de-listed MWs will be permitted where:
- Generation equal to 100% of a unit (which is only 50% listed) is offered into the DAEM and there is no DAEM schedule for the unit. Can the de-listed MWs be bid into the RTEM in all hours? If not, are the de-listed MWs limited to self-scheduling into the RTEM.
- Generation equal to 100% of a unit (which is only 50% listed) is offered into the DAEM and 50% of the unit is scheduled as energy in some, but not all hours of the DAEM. Can the de-listed MWs be bid into the RTEM in all hours? If not, are the de-listed MWs limited to self-scheduling into the RTEM.
- Generation equal to 100% of a unit (which is only 50% listed)is offered into the DAEM and 50% of the unit is scheduled as energy in all hours of the DAEM. Can the de-listed MWs be bid into the RTEM in all hours? If not, are the de-listed MWs limited to self-scheduling into the RTEM.
- Generation equal to 80% of a unit (which is only 50% listed) is offered into the DAEM and there is no DAEM schedule for the unit. Can the de-listed MWs offered into the DAEM (30% of unit) be bid into the RTEM in all hours? If not, are those de-listed MWs limited to self-scheduling into the RTEM.
- Generation equal to 80% of a unit (which is only 50% listed) is offered into the DAEM and 50% of the unit is scheduled as energy in some, but not all hours of the DAEM. Can the de-listed MWs offered into the DAEM (30% of unit) be bid into the RTEM in all hours? If not, are those de-listed MWs limited to self-scheduling into the RTEM.
- Generation equal to 80% of a unit (which is only 50% listed) is offered into the DAEM and 50% of the unit scheduled as energy in all hours of the DAEM. Can the de-listed MWs offered into the DAEM (30% of unit) be bid into the RTEM in all hours? If not, are those de-listed MWs limited to self-scheduling into the RTEM.
- If de-listed MWs were either not offered in a DAEM bid or the term "accepted" is interpreted to require the MWs to "clear" in the DAEM (in at least one of the 24 hours), the associated generation not "bid" or "not cleared" in the DAEM must be self-scheduled into the RTEM in order to sell into the RTEM. Will the NCPC uplift rules will be changed to assure that such a self-schedule of de-listed MWs in the RTEM will not compromise the receipt of NCPC payments for ISO-scheduled MWs (listed or de-listed)? (see note 1)
Note 1 - Under current market rules in which combined cycle resources are not penalized for ambient temperature derates in the UCAP market and all MWs must be offered into the RTEM, the self-schedule of generation in an hour renders the entire resource ineligible for uplift in that hour. Under FCM, combined cycle generators are left to manage their Shortage Event penalty risk by de-listing MWs potentially unavailable due to ambient temperature derates and, once de-listed, the resource owner will be required to self-schedule (at least in some circumstances) in order for those de-listed MWs to participate in the RTEM. If the requirement that such MWs need to be self-scheduled into the RTEM is coupled with the consequence of that self-schedule implementation compromising the resource's NCPC uplift eligibility for the ISO-scheduled MWs, this would appear to hamper the ability of a combined cycle resource owner to mitigate its Shortage Event penalty risk (by de-listing MWs subject to ambient temperature derates).
"Accepted" in this context means the de-listed capacity clears and receives a schedule at some level in one or more hours resulting from the Day-Ahead Energy Market clearing process.
Pursuant to Part IV.B.4 of the Settlement Agreement and Section III.13.6.2.1.1.2 of the Tariff, de-listed capacity that is not offered in the Day Ahead Energy Market or that is offered in the Day-Ahead Energy Market but not accepted must be self-scheduled in order to participate in the Real-Time Energy Market. This requirement currently applies in the same manner whether the de-listed capacity is associated with a fully or partially de-listed resource. However, the ISO will in the near future propose to stakeholders a change in this treatment with respect to partially de-listed resources.
Specifically, where de-listed capacity from a partially de-listed resource is offered in the Day-Ahead Energy Market but not accepted, the ISO will propose that the day-ahead offer be carried forward into the Real-Time Energy Market, subject to re-offer period modifications and redeclarations. The resource may choose to make additional MW above its offer level available to the ISO for economic dispatch.
Under the proposed revisions, if a partially de-listed resource chooses to offer some or all of its de-listed capacity in the Day-Ahead Energy Market, that offer will be carried forward to the Real-Time Energy Market, obviating the need to self-schedule in order to run in real-time. This arrangement would likely also require the resource to provide a physical reason in order to redeclare the resource down in real time.
Each of the six examples presented describes a resource that has a Capacity Supply Obligation for less than 100 percent of its capability (that is, a resource that is partially de-listed). The response is the same with respect to each of the circumstances described. Under the current rules, the de-listed capacity offered in the Day-Ahead Energy Market but not accepted would be limited to self-scheduling in the Real-Time Energy Market. However, as described above, the ISO will soon be proposing a change to the rules such that the de-listed capacity from a partially de-listed resource that is offered in the Day-Ahead Energy Market but not accepted can be bid into the Real-Time Energy Market in all hours without being limited to self-scheduling. Specifically, in such a case, the Day-Ahead Energy Market Supply Offer will be carried forward into the Real-Time Energy Market, subject to re-offer period modifications and redeclarations.
Under the rules to be proposed by the ISO, a resource with no Capacity Supply Obligation (fully de-listed) that offers and is accepted in the Day-Ahead Energy Market will have the opportunity, via the re-offer and redeclaration processes, to make additional MW above the day-ahead offered level available to the ISO for economic dispatch. A resource with no Capacity Supply Obligation that offers in the Day-Ahead Energy Market but is not accepted and that elects to self-schedule in the Real-Time Energy Market will have the opportunity, via the re-offer and redeclaration processes, to make additional MW above the self-scheduled level available to the ISO for economic dispatch. The same would be true for a resource with a Capacity Supply Obligation less than its full capability (partially de-listed). As described above, the ISO will soon propose rule changes that would require that a partially de-listed resource's Day-Ahead Energy Market supply offer be carried forward to the Real-Time Energy Market, regardless of whether it is accepted in the Day-Ahead Energy Market. Such a resource also would have the opportunity, via the re-offer and redeclaration processes, to make additional MW (above those included in its Day-Ahead Energy Market supply offer) available to the ISO for economic dispatch in real time.
Please note that the NCPC rules are currently undergoing an evaluation to assess whether conforming changes are required. The provisions described above and any identified changes to NCPC rules will be proposed via the stakeholder process.
