FERC accepts New York ISO interconnect policy changes

The Federal Energy Regulatory Commission on Jan. 23 accepted some proposed changes from the New York ISO in the power plant interconnection procedures related to plant uprates.

On Dec. 16, 2013, 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. NYISO proposed to use a de minimus criteria for determining when any increase in the capability of existing generating facilities is required to undergo the NYISO interconnection study procedures.

NYISO proposed 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 any case where the increase is no more than 10 MW or 5% of a facility’s existing ERIS capability, whichever is greater. Similarly, an increase in a small generating facility’s ERIS capability 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.

“This acceptance for filing shall not be construed as constituting approval of the referenced filing or of any rate, charge, classification, or any rule, regulation, or practice affecting such rate or service contained in your filing; nor shall such acceptance be deemed as recognition of any claimed contractual right or obligation associated therewith; and such acceptance is without prejudice to any findings or orders which have been or may hereafter be made by the Commission in any proceeding now pending or hereafter instituted by or against NYISO,” said the Jan. 23 decision. “This order constitutes final agency action. Requests for rehearing by the Commission may be filed within 30 days of the date of issuance of this order.”
