Re:    New York Independent System Operator, Inc., Refiling of Tariff Section
to Correct Ministerial Error; Docket No. ER13-102-___

Dear Secretary Bose:

On March 19, 2018, the New York Independent System Operator, Inc. (“NYISO”) filed
with the Federal Energy Regulatory Commission (“Commission”) in the above-referenced
docket revisions to Section 31.2 of the NYISO’s Open Access Transmission Tariff (“OATT”) to
fulfill the directives of the Commission in its February 15, 2018, Order Conditionally Accepting
Tariff Revisions and Requiring Further Compliance.1  That filing is pending before the
Commission.  In that filing, the NYISO inadvertently used an incorrect base document, which
included language in Section 31.2.11 of the OATT that the Commission rejected in its April 21,
2016, Order on Compliance and Rehearing,2 to create the clean and blacklined versions of
Section 31.2.8-31.2.13 of the OATT.  The NYISO respectfully submits this filing to resubmit
the proposed revisions to that section with the rejected language removed.

I.Description of Filing

The NYISO identified a ministerial error in its March 19 Filing where the NYISO used
an incorrect base document to create the clean and blacklined versions of the proposed revisions
to Section 31.2.8-31.2.13 of the OATT.3  Specifically, the base document included language in

1 New York Independent System Operator, Inc., Compliance Filing, Docket No. ER13-102-012 (March 19, 2018) (“March 19 Filing”).

2 New York Independent System Operator, Inc., Order on Compliance and Rehearing, 155 FERC ¶ 61,076 (2016) (“April 2016 Order”).  See generally, New York Independent System Operator, Inc., Notice of Extension of Time, Docket Nos. ER16-120-000, EL15-37-001 (May 21, 2016).

3 In the March 19 Filing, a second, clean version of OATT Section 31.2.8-31.2.13 was submitted with an
effective date of October 18, 2017.  This version brought the proposed revisions forward to complete the record for

Section 31.2.11 of the OATT that the Commission rejected in its April 2016 Order.  The

inadvertently included language does not interact with or affect the language proposed in the
March 19 Filing, and the NYISO is not proposing any changes to those revisions in this filing.
Attachments I and II to this filing letter contain a corrected clean and blackline version,
respectively, of the proposed revisions to Section 31.2.8-31.2.13 of the OATT.  The attachments
should replace the Tariff records on file with the Commission in this pending docket.

II.Effective Date

The NYISO respectfully requests that the Commission accept the tariff revisions

resubmitted in this errata filing with an effective date of April 1, 2016, which is consistent with the effective date requested in the March 19 Filing.

III.Documents Submitted

The NYISO respectfully submits the following documents with this filing letter:

1. A clean version of the proposed revisions to Section 31.2.8-31.2.13 of the OATT
(“Attachment I”); and

2. A blacklined version of the proposed revisions to Section 31.2.8-31.2.13 of the
OATT (“Attachment II”).

IV.Service

The NYISO will send an electronic link to this filing to the official representative of each
party to this proceeding, to the official representative of each of its customers, to each participant
on its stakeholder committees, to the New York Public Service Commission, and to the New
Jersey Board of Public Utilities.  In addition, the complete filing will be posted on the NYISO’s
website at www.nyiso.com.

that effective date in the Commission’s tariff records.  That second version was filed on the correct base and is not included in the instant filing.

revisions.
