Class Year Study definition

Class Year Study means a Class Year Interconnection Facilities Study as that term is defined in OATT Section 25 (OATT Attachment S).

Class Year Study means a study conducted by the ISO or a third party consultant for the Developer to determine a list of facilities (including Connecting Transmission Owner’s Attachment Facilities, Distribution Upgrades, System Upgrade Facilities and System Deliverability Upgrades as identified in the Interconnection System Reliability Impact Study), the cost of those facilities, and the time required to interconnect the Large Generating Facility or Class Year Transmission Project with the New York State Transmission System or with the Distribution System. The scope of the study is defined in Section 30.8 of the Large Facility Interconnection Procedures in Attachment X to the ISO OATT.

Class Year Study means a study conducted by the NYISO or a third party consultant for the Interconnection Customer to determine a list of facilities (including Connecting Transmission Owner’s Attachment Facilities, Distribution Upgrades, System Upgrade Facilities and System Deliverability Upgrades as identified in the Interconnection System Reliability Impact Study), the cost of those facilities, and the time required to interconnect the Large Generating Facility or Class Year Transmission Project with the New York State Transmission System or with the Distribution System. The scope of the study is defined in Section 30.8 of the Large Facility Interconnection Procedures in Attachment X to the ISO OATT.

Examples of Class Year Study in a sentence

• If a Developer in Additional SDU Study accepted its SUF Project Cost Allocation pursuant to Section 25.8.2 of this Attachment S prior to the completion of the Annual Transmission Baseline Assessment study cases for the subsequent Class Year Study, the Project and its SUF will be included in the Existing System Representation for the subsequent Class Year Study.

• A Class Year Study deliverability evaluation first evaluates whether a Project satisfies the NYISO Deliverability Interconnection Standard at its full amount of requested CRIS.

• In a subsequent Class Year Study to evaluate the Developer’s requested CRIS, the Additional SDU Studies will continue; provided, however, the base case used in the Additional SDU Studies will be updated based on the base case inclusion rules for that Class Year Study determined in accordance with Section 25.5.5.1 of this Attachment S.

• For purposes of determining the Class Year Start Date for the next Class Year Study, a Class Year Study is complete on the date upon which the Final Decision Round completes for the Class Year Study decision period commenced in accordance with Section 25.8 of this Attachment S; the date an Additional SDU Study is completed does not impact the Class Year Start Date for the next Class Year Study.

• A Developer requesting CRIS for a Project larger than 2 MW may elect to enter either a Class Year Study or an Expedited Deliverability Study; provided however, a Developer may not be evaluated in both studies simultaneously (i.e., a Developer with CRIS being evaluated in a Class Year Study may not enter an Expedited Deliverability Study for evaluation of the same CRIS request until the Class Year Study has completed.

• This is accomplished, in the Class Year Study, through ensuring the deliverability of each Class Year CRIS Project, in the Capacity Region(s) where the Project interconnects.

• A Developer evaluated in an Expedited Deliverability Study and deemed undeliverable at its full amount of requested CRIS may (1) enter the next Open Class Year Study to obtain a Project Cost Allocation for required System Deliverability Upgrades; or (2) enter into a subsequent Expedited Deliverability Study or Class Year Study with the same or different CRIS request.

• The next Class Year Study may commence prior to completion of an Additional SDU Study if the Additional SDU Study has not completed before the Initial Decision Period commences for the Class Year Study in accordance with Section 25.8.2(1) of this Attachment S.

• A Developer with CRIS being evaluated in an Expedited Deliverability Study may not enter a Class Year Study for evaluation of the same CRIS request until the Expedited Deliverability Study has completed).

• If a Project is not deliverable for its full amount of requested CRIS, the Class Year Study proceeds to identify and cost allocate System Deliverability Upgrades required to make the Project fully deliverable for the full amount of requested CRIS.

More Definitions of Class Year Study

Class Year Study for Class Year 2017 identified the transmission system of Niagara Mohawk Power Corporation d/b/a National Grid (“National Grid”) as an Affected System in connection with the interconnection of the Large Generating Facility. The Class Year Study indicated that National Grid would need to coordinate the protection of its system based on the interconnection of the Large Generating Facility. The Class Year Study estimated the cost of work related to National Grid’s system at $20,000, which costs were included in the Project Cost Allocation. The Developer accepted its Project Cost Allocation and posted the related Security. The Developer and Connecting Transmission Owner shall coordinate with National Grid, and enter into any required study agreement with National Grid, concerning National Grid’s evaluation of the impacts of the interconnection on its system. If National Grid determines that physical upgrades are required on its system to coordinate system protection, the Developer, National Grid, the Connecting Transmission Owner, and the NYISO will enter into an Engineering, Procurement, and Construction Agreement to address this work. The Developer shall be responsible for the costs associated with National Grid’s work; provided, however, that any costs that are above the Project Cost Allocation identified in the Class Year Study and accepted by the Developer shall be allocated in accordance with Section 25.8.6 of Attachment S of the NYISO OATT.
