Re: Supplemental Filing to

Motion of New York Independent System Operator, Inc. to Defer Effective Date of Compliance Tariff Revisions;
Docket No. ER13-102-003

Dear Ms. Bose:

On July 2, 2014, the New York Independent System Operator, Inc. (“NYISO”) filed a
motion requesting that the Federal Energy Regulatory Commission (“Commission”) defer the
proposed effective date for the revisions to the NYISO’s Open Access Transmission Tariff
(“OATT”) and Market Administration and Control Area Services Tariff (“Services Tariff”) to
bring its Comprehensive System Planning Process into compliance with the Order No. 1000
regional transmission planning requirements.1 The NYISO submitted with its motion clean
versions of the OATT and Services Tariff sections that contain the tariff revisions filed in

response to the Order No. 1000 regional requirements, replacing the previously proposed effective date for these tariff sections with an open effective date.2

Following discussions with Commission staff on July 3, 2014, the NYISO submits

herewith a supplemental ministerial filing to provide redline versions of the OATT and Services
Tariff sections for which the NYISO is requesting a revised effective date. The NYISO also re-
submits the related clean versions. The redline versions of the tariff sections are set against the

1 New York Independent System Operator, Inc., Motion of New York Independent System Operator, Inc. to Defer Effective Date of Compliance Tariff Revisions; and Request for Shortened Comment Period, Docket No. ER13-102-003 (July 2, 2014) (“July 2 Motion”). On July 3, 2014, the Commission issued its notice of the NYISO’s motion. New York Independent System Operator, Inc., Notice of Compliance Filing, Docket No. ER13-102-003 (July 3, 2014)

2 The NYISO requested that the Commission direct it to submit a compliance filing that reflects
the revised effective dates requested in the motion for the affected tariff provisions. July 2 Motion at p

The redlines are identical to the clean versions, as the NYISO is not proposing any changes to these tariff sections, except to modify the effective date. The revisions to the effective date are provided in the metadata of the Commission’s eTariff system.

I.LIST OF DOCUMENTS SUBMITTED

With this transmittal letter, the NYISO submits:

1. A clean version of the revisions to the OATT (“Attachment I”);

5 The revisions to Section 30.4 of the Services Tariff submitted in the November 25, 2013, filing in Docket No. ER14-461-000 were unrelated to Order No. 1000. Consistent with the NYISO’s longstanding practice, the NYISO’s tariff revisions to Section 30.4 were submitted on top of the latest clean version of that section, which included revisions proposed by the NYISO in the Order No. 1000
proceeding in its October 11, 2012, and October 15, 2013, compliance filings.
