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.

Examples of Class Year Study in a sentence

• An existing Large Generating Facility requesting only CRIS must request CRIS in an Open Class Year Study or an Expedited Deliverability Study unless it is requesting CRIS pursuant to Section 30.3.2.6 of this Attachment X.

• If no Class Year Project Developer to which the Notice of SDUs Requiring Additional Study is issued elects to proceed with such additional studies, the Class Year Study will proceed to the decision and settlement phase set forth in Section 25.8.2 of this Attachment S.

• 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.

• 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).

• Consistent with the analyses performed in the Class Year Study under Section 25.6 of Attachment S, the ISO shall evaluate the impact on short circuit, thermal, voltage, or stability of unbuilt Attachment Facilities and System Upgrade Facilities and/or System Deliverability Upgrades associated with Class Year Projects.

• If the Developer does not elect to pursue an Additional SDU Study for required System Deliverability Upgrades, it may only accept or reject its Deliverable MW, if any, in the Class Year Study.

• If the ISO does not receive the Developer’s election by the deadline, the Developer will be deemed to have (1) notified the ISO that it elects to not proceed with an Additional SDU Study for the identified System Deliverability Upgrades; and (2) will only be permitted to accept or reject its Deliverable MW, if any, in the Class Year Study.

• The preliminary deliverability evaluation will be performed in accordance with the Class Year Study deliverability procedures set forth in Sections 25.7.3, 25.7.5, 25.7.8 and 25.7.9 of Attachment S to the OATT; provided, however, that the Large Facility will be evaluated individually and not on an aggregate basis with other projects.

• Class Year Start Date shall mean the deadline for Eligible Class Year Projects to enter a Class Year Study, determined in accordance with Section 25.5.9 of Attachment S.

• During the Optional Interconnection Feasibility Study, System Reliability Impact Study, or Class Year Study, as applicable, the Connecting Transmission Owner and Affected Transmission Owner(s), identified pursuant to Section 30.3.5 of this Attachment X, shall provide input regarding proposed Point(s) of Interconnection and configurations.

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.
