The New York Independent System Operator, Inc. (“NYISO”) and its external Market
Monitoring Unit (“MMU”), Potomac Economics, Ltd., jointly submit this response to the Federal Energy Regulatory Commission’s (the “Commission’s”) deficiency letter issued in this
proceeding on December 28, 2015 (“Deficiency Letter”). The Deficiency Letter directs the
NYISO to respond to five enumerated questions. Responses to each of the Commission’s
questions are provided in Attachment I to this letter.
In addition to the attached responses to the Commission’s questions, the NYISO
resubmits its proposed Tariff revisions as Attachment II to this letter, and proposes to change the

requests that the Tariff revisions proposed in its October 29, 2015 filing be permitted to become
effective on the date of the Commission’s issuance of an order ruling on the NYISO’s proposed
Tariff revisions. The NYISO respectfully requests that the Commission issue an order ruling on
the NYISO’s proposed Tariff revisions within 60 days of the date of this response.
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
