25.3 Deliverability Interconnection Standard
25.3.1 Scope and Purpose of Standard
Each proposed or existing facility larger than 2 MW, and each facility with CRIS that requests an increase to its CRIS, must meet the NYISO Deliverability Interconnection Standard before it can receive CRIS or Unforced Capacity Deliverability Rights, unless otherwise provided for in this Attachment S. For purposes of this Section 25.3.1, a facility comprised of multiple Generators is a single “facility.”
Pursuant to Section 32.1.1.7 of Attachment Z to the OATT, a Small Generating Facility 2 MW or smaller may obtain CRIS without being evaluated for deliverability under the NYISO Deliverability Interconnection Standard. The requirement that a facility not subject to the ISO’s Large Facility Interconnection Procedures or Small Generator Interconnection Procedures must meet the NYISO Deliverability Interconnection Standard to become a qualified Installed Capacity Supplier first applies on May 19, 2016, subject to the transition rule specified in Section 25.9.3.4.1 of this Attachment S.
Any facility with an established CRIS value may, at a later date, without submitting a new Interconnection Request, ask the ISO to reevaluate the facility for a higher level of MW of Installed Capacity, not to exceed the permissible levels of CRIS that may be requested pursuant to Section 25.8.1 of this Attachment S, by entering a Class Year Study or Expedited Deliverability Study to identify requested increase in CRIS MW is deliverable. Any facility with an established CRIS value may, without such evaluation and without submitting a new Interconnection Request, increase its existing CRIS value by a total of no more than 2 MW of Installed Capacity during the operating life of the facility; provided however, for Projects comprised of multiple Generators, this CRIS increase up to 2 MW is permitted only at the facility (i.e., Project) level, not at the individual Generator level. A facility that receives this up to 2 MW CRIS increase, to the extent it later combines with another facility or Project to become a multi-Generator co-located resource (e.g., a Co-located Storage Resource, Hybrid Storage Resource or Distributed Energy Resource), is not eligible for any additional CRIS increase above 2 MW, including the MW of CRIS increase already received pursuant to this Section 25.3.1, without proceeding through a deliverability evaluation in a Class Year Study or Expedited Deliverability Study.
Pursuant to Section 30.3.2.6 of Attachment X to the ISO OATT, an “established CRIS value” for facilities subject to a CRIS set and reset period pursuant to Sections 25.9.3.3, 25.9.3.1.4.1, 25.9.3.1.4.2, or 25.9.3.5 of this Attachment S is the final CRIS value established after the termination of the CRIS set and reset period.
As defined in Section 25.1 of this Attachment S, the term “Large Facility” includes a Class Year Transmission Project. A Class Year Transmission Project, as such term is defined in Section 25.1 of this Attachment S, includes any proposed new transmission facility that will interconnect to the New York State Transmission System or a proposed upgrade—an improvement to, addition to, or replacement of a part of an existing transmission facility—to the New York State Transmission System, for which (1) the Developer is eligible to request and does request CRIS—in the form of Unforced Capacity Deliverability Rights or External-to-ROS Deliverability Rights, as applicable, subject to the eligibility requirements set forth in the ISO Procedures; or (2) the Developer requests only ERIS and the transmission facility for which it requests ERIS is a transmission facility over which power flow can be directly controlled by power flow control devices directly connected to the Class Year Transmission Project without having to re-dispatch generation. Class Year Transmission Projects shall not include Attachment Facilities, Network Upgrade Facilities, System Upgrade Facilities or System Deliverability Upgrades.
25.3.1.1 The NYISO Deliverability Interconnection Standard is designed to ensure that the Project is deliverable throughout the New York Capacity Region(s) where the Project will interconnect or is interconnected. The NYISO Deliverability Interconnection Standard is also designed to ensure that the Developer of the Project restores the transfer capability of any Other Interfaces degraded by its interconnection.
25.3.1.2. Each Project electing CRIS will be allowed to become an Installed Capacity Supplier, or will be allowed to receive Unforced Capacity Deliverability Rights or External-to-ROS Deliverability Rights, in accordance with the rules of the New York Installed Capacity market, up to the amount of its deliverable capacity, as that amount is determined in accordance with the rules in this Attachment S, once the Developer of the Project has funded or committed to fund any required System Deliverability Upgrades in accordance with the rules in this Attachment S.
