UNITED STATES OF AMERICA
BEFORE THE

FEDERAL ENERGY REGULATORY COMMISSION

New York State Reliability CouncilDocket No. ER13-572-000

MOTION TO INTERVENE AND COMMENTS OF

THE NEW YORK INDEPENDENT SYSTEM OPERATOR, INC.

Pursuant to Rules 212 and 214 of the Commission’s Rules of Practice and Procedure, 18
C.F.R. §§ 385.212, 385.214 (2006), the New York Independent System Operator, Inc.
(“NYISO”) respectfully moves to intervene in this proceeding and offers its comments in support
of the filing made by the New York State Reliability Council (“NYSRC”). The NYISO believes
that an Installed Reserve Margin (“IRM”) of 17.0 percent for the New York Control Area
(“NYCA”) for the upcoming 2013/2014 Capability Year,1 which runs from May 1, 2013
through April 30, 2014, falls within a range of reasonable determinations for the level of
installed capacity required to maintain the reliability of the NYCA bulk power system.
Accordingly, the NYISO supports the NYSRC’s request that the Commission approve an IRM
of 17.0 percent.

The NYISO requests that the Commission grant any waivers that may be necessary to

accept and approve the NYSRC’s filing effective February 15, 2013. This date allows sufficient time for the NYISO to calculate and post the minimum capacity requirements and for market participants to prepare for the first Installed Capacity (“ICAP”) auction for the Summer 2013 Capability Period, scheduled for March 28-29, 2013. Without this basic information, the
efficiency of the NYISO’s installed capacity auction could be seriously impaired.

1 Capitalized terms have the meaning ascribed to them in the NYISO’s Market Administration and Control Area Services Tariff (“Services Tariff”).

Finally, as in prior years the NYISO respectfully suggests that the Commission

coordinate its decision in this proceeding with the actions that the New York Public Service
Commission (“NYPSC” or “State Commission”) may soon take in response to the NYSRC’s filing. Inconsistent determinations by the Commission and the NYPSC would create uncertainty about what IRM the NYSRC should provide to the NYISO to use, and, potentially, subject the NYISO to contradictory regulatory mandates. At the same time, the NYISO respectfully
requests that the Commission not allow jurisdictional considerations to delay timely
implementation of the auction process.

In support thereof, the NYISO states:

II.Background

Section 3.03 of the NYSRC Agreement, which was approved by the Commission as part

of the formation of the NYISO and the NYSRC, obligates the NYSRC to submit any proposed revisions to the NYCA IRM to the Commission for approval before the beginning of the

Capability Year to which the change would apply. The IRM was set at 18.0% between the

2000/2001 and the 2006/2007 Capability Years.2 The Commission accepted an IRM of 16.5% for the 2007/2008 Capability Year,3 15% for the 2008/2009 Capability Year,4 16.5% for the 2009/2010 Capability Year, 5 18.0% for the 2010/2011 Capability Year,6 15.5% for the
2011/2012 Capability Year7 and 16.0% for the current Capability Year.8

The current NYCA IRM of 16.0% means that Load Serving Entities (“LSEs”) in the

NYCA must procure ICAP equal to 116.0% of their forecast peak load.9 In addition, there are separate location-specific ICAP requirements for LSEs in New York City and on Long Island that reflect the existence of transmission constraints in those areas.

At the request of the NYSRC, the NYISO conducted a technical study to provide

parameters for establishing NYCA IRM requirements for the 2013/2014 Capability Year. The
NYISO employed General Electric’s Multi-Area Reliability Simulation (MARS) model to
determine the amount of installed capacity that is required NYCA-wide to meet the governing
resource adequacy criterion that the probability of an unplanned disconnection of firm load not
exceed one occurrence in ten years.10 The NYISO’s base case evaluation yielded a minimum
NYCA IRM of 17.1 percent for the 2013/2014 Capability Year. The NYISO reported its results
to the NYSRC’s Installed Capacity Subcommittee in the Technical Study Report.

The subcommittee reviewed the results of the study, with verification of the data inputs

9 For the 2006/2007 Capability Year, for example, the forecast peak load for the NYCA was 33,295 MW. The

18.0% IRM means the minimum ICAP requirement was 39,288 MW (i.e., 18% more than 33,295 MW).

and modeling by General Electric. The NYSRC’s filing provides highlights of the Technical

Study Report at pages 8, 9, 10, and 11 and includes the study itself as an attachment. As described
in its filing, the NYSRC Executive Committee relied on this base case result as well as its
evaluation of modeling and assumption changes and numerous sensitivity studies, which
resulted in IRMs higher and lower than the base case IRM. Based upon its experience and
expertise, the NYSRC adopted an IRM for the 2013/2014 Capability Year of 17.0 percent.

On December 17, 2012, the NYSRC filed its proposed 2013/2014 NYCA IRM with the Commission. The NYSRC requested that the Commission accept its filing and issue an order no later than February 15, 2013.

The NYSRC has informed the NYISO that, consistent with past practice, it intends to
provide a copy of its filing to the NYPSC. The NYISO expects that the NYPSC will initiate a
proceeding to review the proposed IRM and will accept comments from interested parties. The
NYISO plans to file comments with the State Commission in support of the NYSRC’s proposal.

III.Motion to Intervene

The NYISO is the independent body responsible for providing open access transmission service, maintaining reliability, and administering competitive wholesale markets for electricity, capacity, and ancillary services in New York State. Pursuant to its Commission-approved
tariffs, the NYISO is also responsible for administering the ICAP auctions, including the
Capability Period Auction scheduled for March 28-29, 2013.11 The NYISO’s Services Tariff also requires LSEs within the NYCA to procure sufficient levels of ICAP, including locational ICAP requirements for New York City and Long Island.

Together with the ICAP Demand Curves, the NYCA IRM is a critical input into the

11 The ICAP auction processes are described in Sections 5.13 and 5.14 of the Services Tariff.
4

NYISO’s ICAP auctions because it is used to calculate the LSEs’ minimum NYCA-wide

capacity requirements, and its methodology and data inputs are used to calculate the Locational
Capacity Requirements (“LCRs”). Specifically, after the NYSRC provides the IRM to the
NYISO, the NYISO uses the NYSRC’s IRM to determine the capacity requirements for New
York State as a whole. It then uses the methodology and data underlying the determination of
the base case for the IRM, and the IRM determined by the NYSRC, to calculate the LCRs for
LSEs. Those LCRs, together with the demand curve, determine the minimum amount of
capacity that must be procured by LSEs. The NYISO informs the LSEs of their minimum
capacity requirements and conducts auctions for each Capability Period (summer and winter six-
month capability periods) as well as monthly and spot market auctions.12 Because the NYISO
cannot fulfill its tariff obligations without the IRM, the NYISO has a unique interest in this
proceeding that cannot be adequately represented by any other entity and should therefore be
permitted to intervene with all rights of a party.

IV.Comments

A.The NYSRC’s Proposal to Establish a NYCA IRM of 17.0% is

Reasonable.

As explained above, the NYSRC has requested Commission approval to increase the

NYCA IRM from 16.0 percent to 17.0 percent. The NYISO believes that the proposed IRM
falls within a range of potentially reasonable IRM levels. As was noted above, the NYSRC’s
technical study yielded a base case that resulted in a minimum NYCA IRM of 17.1 percent.
The NYSRC Executive Committee determined, based upon the base case result, modeling and
assumption changes and numerous sensitivities, that a 17.0 percent IRM satisfies the resource
adequacy criterion and should be adopted. The NYISO will adjust the LCRs to meet the LOLE

12 See Services Tariff §§5.12-5.14

resource adequacy criterion. The NYISO believes that it was reasonable for the NYSRC to

have adopted the 17.0 percent level because it correctly applied the LOLE criterion and the

Technical Study Report to select an IRM level within a range of reasonable IRM levels that will maintain reliability in New York for the upcoming 2013/2014 Capability Year.

B. The Commission Should Act Expeditiously.

The NYISO requests that the Commission act in time to provide a decision by February
15, 2013. Pursuant to its tariff, the NYISO has scheduled the first ICAP auction for the six-
month Summer 2013 Capability Period to occur on March 28 and 29, 2013.13 The outcome of
this auction will affect the monthly and spot capacity auctions the NYISO will conduct in April
for May 2013.

The NYISO must know the NYCA IRM sufficiently ahead of the scheduled auction so
that it can calculate the minimum NYCA-wide and locational capacity requirements and
transmit this information to auction participants. If the Commission acts by February 15, 2013 -
the 60th day after the NYSRC filing - the NYISO is confident that it could complete this work
on time.

Moreover, in accordance with its manuals and past practice, the NYISO has informed
Market Participants that the new minimum requirements will be available by March 18, 2013.
This information is conveyed in advance of the capacity auction for the six-month Summer
Capability Period in order to provide Market Participants with sufficient notice of their capacity
requirements so that they may develop or adjust their bidding strategies. The NYISO would
prefer to start making the necessary calculations as early as possible in advance of this deadline.

13 The NYISO intends to ask the NYPSC to act promptly in considering the proposed IRM level, for the same reasons discussed herein.

Further, without timely information, it will be much harder for ICAP Suppliers and LSEs to make economically-efficient capacity procurement decisions.

C.The Commission Should Coordinate with the NYPSC to Avoid Imposing

Inconsistent Requirements on the NYSRC.

As in previous years, the NYISO respectfully suggests that the Commission coordinate

its review of the NYSRC’s proposed NYCA IRM revision with the NYPSC’s inquiry into the

subject. To the extent that both the Commission and the NYPSC address common questions, the
NYISO also asks that the Commission take measures to ensure that its determinations are
compatible with the NYPSC’s. If the two agencies were to issue conflicting or contradictory
orders to the NYSRC concerning the IRM level, confusion may ensue as to what IRM level the
NYSRC should provide to the NYISO to use in the locational capacity calculations. If the
NYSRC receives conflicting regulatory directives, it will be forced to choose between them,
leaving its choice susceptible to almost certain litigation. The probability of such litigation and
the uncertainty as to its outcome will engender uncertainty about the LSEs’ minimum
requirements for the auction for the six-month Summer Capability Period (and possibly even the
subsequent monthly and spot auctions). The resulting disruption and confusion would negatively
affect the NYISO-administered markets, and, potentially, threaten the reliability of the New
York State transmission system.

Conflicting Commission and NYPSC rulings could also put the NYISO in the difficult position of being subject to inconsistent federal and state requirements. This would greatly
complicate the NYISO’s ability to fulfill its ICAP-related responsibilities under its tariffs. The NYISO could also be exposed to demands for refunds, and other legal claims, from either LSEs claiming that the NYISO unlawfully required them to over-procure, or from generators alleging an unlawful under-procurement and lost revenues.

The NYISO recognizes that the parallel Commission and NYPSC reviews of the

NYSRC’s proposed NYCA IRM revisions may give rise to disagreement between the agencies
as to whether the Commission or the NYPSC, or both, have jurisdiction over the NYCA IRM. If a
jurisdictional dispute arises, the NYISO respectfully submits that the Commission should not
allow the possibility of such a dispute to interfere with the timely administration of the ICAP
auctions.

V.Conclusion

WHEREFORE, for the foregoing reasons, the New York Independent System Operator,
Inc. respectfully requests that the Commission: (i) accept its motion to intervene; (ii) accept the
NYSRC’s proposed revision to the NYCA IRM with an effective date of February 15, 2013;
and (iii) coordinate with the NYPSC in order to avoid the possibility of inconsistent federal and
state rulings.

Respectfully submitted,
