40.19 Expedited Deliverability Study Procedures
40.19.1 Study Start Date
After the completion of the initial Expedited Deliverability Study, each Expedited Deliverability Study will begin the first Business Day after thirty (30) Calendar Days following the completion of the prior Expedited Deliverability Study; provided, however, that an Expedited Deliverability Study may not commence during the period between the posting of, as applicable, the draft Class Year Study or Phase 2 Cluster Study report for Operating Committee approval and commencement of the next Phase 1 Study. If the first Business Day after thirty (30) Calendar Days following the completion of the prior Expedited Deliverability Study falls on a date within the above-described Class Year or Cluster Study decision and settlement period, the Expedited Deliverability Study will begin on the first Business Day after ten (10) Calendar Days following the Cluster Study Process Start Date that immediately follows the above-described Class Year or Cluster Study decision and settlement period. The ISO will provide notice of the Expedited Deliverability Study start date by (1) sending notice of the start date to those registered through the ISO to be on the distribution lists for the NYISO Operating Committee and its subcommittees; and (2) posting notice of the Expedited Deliverability Study start date.
40.19.2 Study Entry Requirements and Schedule
In order to become eligible to enter an Expedited Deliverability Study, an Interconnection Customer must (1) elect to enter the Expedited Deliverability Study by providing notice to the ISO by the Expedited Deliverability Study start date; (2) must have satisfied the data submission requirements set forth in Section 23.4.5.7.3.6 of the ISO Services Tariff required for Cluster Study Projects requesting CRIS in a Mitigated Capacity Zone and have such data submission deemed complete by the ISO by the Expedited Deliverability Study start date; and (3) must be in service or have completed one of the following, as applicable: a Class Year Study or Cluster Study for ERIS, a completed facilities study for Small Generating Facilities processed under the Small Generator Interconnection Procedures pursuant to Section 40.3.1, or a utility interconnection study if the facility is not subject to the ISO interconnection procedures under Attachment HH. As set forth in Section 40.13.1, a Project may not be evaluated in both the Cluster Study Process and an Expedited Deliverability Study simultaneously (i.e., an Interconnection Customer with CRIS being evaluated in a Cluster Study Process may not enter an Expedited Deliverability Study for evaluation of the same CRIS request until the Cluster Study has completed. An Interconnection Customer with CRIS being evaluated in an Expedited Deliverability Study may not enter a Cluster Study Process for evaluation of the same CRIS request until the Expedited Deliverability Study has completed).
A Project that satisfies the eligibility requirements for an Expedited Deliverability Study will become a member of the Expedited Deliverability Study if it satisfies the requirements of Section 40.19.3 of this Attachment HH as it relates to completion of an Expedited Deliverability Study Agreement, submission of the required deposit, and submission of required technical data.
All parties engaged in performing study work as part of the Expedited Deliverability Study are required to use Reasonable Efforts to complete the basic required evaluations in order for the Expedited Deliverability Study to be presented to the NYISO Operating Committee for approval within four (4) months from the date that the ISO confirms receipt of all of the following for all members of the Expedited Deliverability Study: (1) the executed Expedited Deliverability Study Agreement; (2) the $30,000 Expedited Deliverability Study deposit required by Section 40.19.3 of this Attachment HH; and (3) the technical data required by Section 40.19.3 of this Attachment HH.
40.19.3 Expedited Deliverability Study Agreement and Invoicing of Study Costs
40.19.3.1 As soon as practicable after an Interconnection Customer has notified the ISO of its request to enter the next Expedited Deliverability Study, the ISO shall tender an Expedited Deliverability Study Agreement in the form of Appendix 8 to this Attachment HH. When the ISO tenders an Expedited Deliverability Study Agreement to an Interconnection Customer, the ISO shall, at the same time, also provide one to the applicable Connecting Transmission Owner. The Expedited Deliverability Study Agreement shall provide that the Interconnection Customer shall compensate the ISO for the actual cost of the Expedited Deliverability Study. When the ISO tenders the Expedited Deliverability Study Agreement to the requesting Interconnection Customer, the ISO shall provide to the Interconnection Customer a non-binding good faith estimate of the cost and timeframe for completing the Expedited Deliverability Study.
40.19.3.2 Within ten (10) Business Days after the ISO tenders the Expedited Deliverability Study Agreement, the Interconnection Customer shall complete the Expedited Deliverability Study Agreement and deliver the completed agreement to the ISO. Interconnection Customer shall indicate, in the data form attached to the Expedited Deliverability Study Agreement, the MW level of requested CRIS up to the levels permitted by Section 40.5.6.5 of this Attachment HH. Interconnection Customer shall, with the completed Expedited Deliverability Study Agreement, deliver to the ISO (1) the required technical data and (2) a study deposit of $30,000 in accordance with the requirements in Section 40.2.4.
40.19.3.3 The Interconnection Customer, ISO and Connecting Transmission Owner shall execute the Expedited Deliverability Study Agreement no later than ten (10) Calendar Days after the ISO confirms receipt of the completed Expedited Deliverability Study Agreement, the required technical data, and the required deposit from the Interconnection Customer. The ISO shall provide a copy of the fully executed Expedited Deliverability Study Agreement to the Interconnection Customer and Connecting Transmission Owner.
40.19.3.4 The ISO shall invoice the Interconnection Customer in accordance with the requirements in Section 40.24.3.
40.19.4 No Prioritization of Projects in an Expedited Deliverability Study
There will be no prioritization of the Projects grouped and studied together in an Expedited Deliverability Study. Each Project in an Expedited Deliverability Study will, with other Projects in the same Expedited Deliverability Study, share in the then currently available functional or electrical capability of the transmission system in accordance with the rules set forth herein. For purposes of this Section 40.19.4, the “then currently available functional or electrical capability of the transmission system” is the functional or electrical capability of the transmission system currently available in the applicable base case.
40.19.5 Expedited Deliverability Study Procedures
The ISO shall perform the Expedited Deliverability Study in accordance with the requirements for an Expedited Deliverability Study in Section 40.13 of this Attachment HH. The ISO shall coordinate the Expedited Deliverability Study and shall utilize existing studies to the extent practicable in performing the Expedited Deliverability Study. The ISO may request additional information from the Interconnection Customer and Connecting Transmission Owner as may reasonably become necessary consistent with Good Utility Practice during the course of the Expedited Deliverability Study. Upon request from the ISO for additional information required for or related to the Expedited Deliverability Study, the Interconnection Customer and Connecting Transmission Owner shall provide such additional information in a prompt manner.
Within ten (10) Business Days of providing a draft Expedited Deliverability Study report to an Interconnection Customer, the ISO, Connecting Transmission Owner, and Affected System Operator(s) shall meet with the Interconnection Customer to discuss the results of the Expedited Deliverability Study.
The ISO shall use Reasonable Efforts to complete the study and present the Expedited Deliverability Study report to the Operating Committee within the timeframe set forth in Section 40.19.2 of this Attachment HH; provided, however, an Expedited Deliverability Study report shall not proceed to the Operating Committee between Operating Committee approval of a Class Year Study or Phase 2 Study and commencement of the next Phase 1 Study. An Expedited Deliverability Study may not proceed to the Operating Committee until after ten (10) Calendar Days following the completion of the Class Year Study or Phase 2 Study. After Operating Committee approval of the Expedited Deliverability Study report, the Interconnection Customer will be subject to the decision process set forth in Section 25.5.9.2.4.
Before Operating Committee approval of the Expedited Deliverability Study, if the pending Class Year Study or Cluster Study proceeds to the final decision and settlement period and a Class Year Project or Cluster Study Project accepts or rejects a Project Cost Allocation that the ISO determines may impact the deliverability of a Project in the Expedited Deliverability Study, the assumptions used in the Expedited Deliverability Study will be updated before the commencement of the next Phase 1 Study.
At the request of an Interconnection Customer subject to an Expedited Deliverability Study, or at any time the ISO determines that it will not meet the required timeframe for completing the Expedited Deliverability Study, the ISO shall notify the Interconnection Customer as to the schedule status of the Expedited Deliverability Study. If the ISO is unable to complete the Expedited Deliverability Study within the initial schedule, it shall notify the Interconnection Customer and provide an estimated completion date and an explanation of the reasons why additional time is required.
Upon request, the ISO shall provide the Interconnection Customer supporting documentation, workpapers, and databases or data developed in the preparation of the Expedited Deliverability Study, subject to non-disclosure arrangements consistent with Section 40.24.1.
40.19.6 Expedited Deliverability Study Decision Process
Within 5 Business Days following approval of the Expedited Deliverability Study by the Operating Committee (such 5 Business Day period to be referred to as the “Expedited Deliverability Study Initial Decision Period”), each Interconnection Customer in the Expedited Deliverability Study shall provide notice to the ISO, in writing via electronic mail, stating whether it shall accept (an “Expedited Deliverability Study Acceptance Notice”) or not accept (an “Expedited Deliverability Study Non-Acceptance Notice”) the Deliverable MW, if any, reported to it by the ISO in the Expedited Deliverability Study report. Failure to notify the ISO by the prescribed deadline as to whether an Interconnection Customer accepts or rejects its Deliverable MW, if any, will be deemed an Expedited Deliverability Study Non-Acceptance Notice. As soon as practicable following the end of the Expedited Deliverability Study Initial Decision Period, the ISO shall report to all Cluster Study Projects, in writing via electronic mail, all of the decisions submitted by Interconnection Customers in the Expedited Deliverability Study.
At the end of the Expedited Deliverability Study Initial Decision Period, if one or more of the Interconnection Customers provides an Expedited Deliverability Study Non-Acceptance Notice (such event an “Expedited Deliverability Study Non-Acceptance Event”), the Interconnection Customer that provided the Expedited Deliverability Study Non-Acceptance Notice will be removed from the then current Expedited Deliverability Study and the ISO shall update the Expedited Deliverability Study results for those remaining Interconnection Customers in the Expedited Deliverability Study to reflect the impact of the Projects withdrawn from the Expedited Deliverability Study. The revised Expedited Deliverability Study report shall include updated Deliverable MW, if any, and shall be issued within 10 Business Days following the occurrence of an Expedited Deliverability Study Non-Acceptance Event. Each remaining Interconnection Customer shall be deemed to have accepted its respective Deliverable MW identified in the revised Expedited Deliverability Study report.
