Reference:Tariff Revisions to Improve Interconnection Study Processes

Dear Ms. Keegan:

On December 16, 2013, the New York Independent System Operator, Inc. (NYISO) filed tariff revisions to its interconnection procedures set forth in Attachment X and Attachment Z to the NYISO Open Access Transmission Tariff (OATT) to modify the procedures pertaining to the evaluation of increases in the energy capability of existing generating facilities.[1] NYISO proposes to use a de minimus criteria for determining when increase in the capability of existing generating facilities are required to undergo the NYISO interconnection study procedures.

Specifically, NYISO proposes that an increase in an existing large generating facility’s Energy Resource Interconnection Service (ERIS) capability that is associated with non-material equipment changes will not require a new interconnection study in circumstances where the increase is no more than 10 MW or five percent of a facility’s existing ERIS capability, whichever is greater. Similarly, an increase in a small generating facility’s ERIS capability that is associated with non-material equipment changes will not require a new interconnection study in circumstances where the increase is no more than 2 MW and which provides for a total ERIS capability of no more than 20 MW.
