Attachment A to Appendix 5 –Facility MODIFICATION REQUEST

Terms and Conditions of a Facility Modification Request

These terms and conditions for the review and/or study of a request to modify a proposed Generating Facility, Cluster Study Transmission Project, or Class Year Transmission Project or a material modification to an existing Generating Facility, Cluster Study Transmission Project, or Class Year Transmission Project consistent with the Interconnection Request dated ___________ (“Studies”), including any project modifications reviewed and approved by the NYISO, (“the Project”) and submitted by ______________________________

_______________, a __________________ organized and existing under the laws of the State of ____________________ (“Interconnection Customer”), set forth the respective obligations between Interconnection Customer and the New York Independent System Operator, Inc., a not-for-profit corporation organized and existing under the laws of the State of New York (“NYISO”) (hereinafter the “Terms and Conditions”).  By signing below, Interconnection Customer confirms its understanding and acceptance of the Terms and Conditions.

RECITALS

WHEREAS, Interconnection Customer is proposing to develop the Project; and

WHEREAS, Interconnection Customer requests NYISO to evaluate whether the proposed modification to its [Generating Facility, Cluster Study Transmission Project, or Class Year Transmission Project/proposing a capacity addition to an existing Generating Facility, Cluster Study Transmission Project, or Class Year Transmission Project] set forth in the Facility Modification Request would constitute a Material Modification and/or a Permissible Technological Advancement, as applicable, under Attachment HH to the NYISO’s Open Access Transmission Tariff (“OATT”).

NOW, THEREFORE, in consideration of and subject to the terms and conditions contained herein, Interconnection Customer and NYISO agree as follows:

1.0When used in these Terms and Conditions, with initial capitalization, the terms specified shall have the meanings indicated in Section 40.1 of Attachment HH to the ISO OATT.

2.0Interconnection Customer requests NYISO to evaluate whether the proposed modification would constitute a Material Modification and/or a Permissible Technical Advancement, as applicable, and if an additional study(ies) is required pursuant to Section 40.6.3.2 and/or Section 40.6.3.7 of Attachment HH to the OATT, NYISO shall perform, or cause to be performed, a study(ies) consistent with Attachment HH to the OATT.
