Re: New York Independent System Operator, Inc., No. ER11-2906-000;
Compliance Filing to Define Average Coincident Load Baseline
Methodology for Special Case Resources in Section 5.12.11.1 of the
Market Services Tariff
Dear Secretary Bose:
In compliance with the Commission’s April 11, 2011 Letter Order1 regarding
Tariff Revisions for the Special Case Resources Baseline Load Methodology, the New
York Independent System Operator, Inc. (“NYISO”) respectfully submits these proposed
amendments to its Market Administration and Control Area Services Tariff (“Services
Tariff”). These amendments incorporate the methodology and procedures currently
provided in the NYISO Installed Capacity Manual to calculate Average Coincident Load
(“ACL”) and Provisional Average Coincident Load into Sections 5.12.11.1.1 and
5.12.11.1.2 of the Services Tariff, respectively.
I.Documents Submitted
1.This filing letter;
2.A clean version of the proposed revisions to the NYISO’s Services Tariff
(“Attachment I”); and
3.A blacklined version of the proposed revisions to the NYISO’s Services
Tariff (“Attachment II”).
II.Description of Proposed Tariff Revisions
This compliance filing proposes to revise the NYISO Services Tariff by inserting
language currently found in the NYISO’s Installed Capacity Manual (“ICAP Manual”)
1 New York Independent System Operator, Inc., 135 FERC ¶ 61,020 (2011) (“April 11 Letter Order”).

that describes the calculation methodology and procedures associated with the Average
Coincident Load and Provisional Average Coincident Load requirements for Special
Case Resources (“SCR”). The original ICAP Manual language has been slightly
modified where necessary so that the inserted language is consistent with the Services
Tariff; however, no substantive changes have been made to these requirements.
Changes to Specific Provisions of the Services Tariff:
Section 5.12.11.1.1: The proposal modifies the heading of this section in the Services
Tariff from “Special Case Resource Average Coincident Load or Provisional Average
Coincident Load” to “Special Case Resource Average Coincident Load.” The proposed
amendments to this section insert the procedural language and methodology found in the
ICAP Manual that describes the methodology required to determine the Average
Coincident Load of a Special Case Resource. As proposed, the amended tariff language
provides that, for the Summer 2011 Capability Period only, the Average Coincident Load
is calculated using the SCR’s highest twenty (20) one-hour loads that coincide with the
top 50 (fifty) NYCA peak Load hours identified by the NYISO from Load hours during
the Prior Equivalent Capability Period occurring between the 1 P.M. to 7 P.M. No
adjustments are made to the Load for these hours to account for Load reductions achieved
through Transmission Owners’ demand response programs.
For the Winter 2011-2012 Capability Period, and all subsequent Capability Periods, the Average Coincident Load is calculated using the SCR’s highest twenty (20) one-hour loads that coincide with the SCR Load Zone Peak Hours as defined in the Services Tariff and adjusted to account for verified Load reductions that were achieved in response to a Transmission Owner’s demand response program.
Section 5.12.11.1.2: The proposal inserts a new section in the Services Tariff entitled
“Determining a Provisional Average Coincident Load.” This section sets forth the
current procedural requirements used to determine a Provisional Average Coincident
Load to be used for a Special Case Resource that has not previously been enrolled with
the ISO and has never had interval metered Load data for each month in the Prior
Equivalent Capability Period. This section also describes the requirement and
methodology used by the NYISO to perform a verification of the Provisional Average
Coincident Load.
Section 5.12.11.1.3: A new section entitled “Reporting an SCR Change of Status” is proposed using language in the Services Tariff that was relocated from Section
5.12.11.1.1 of the Services Tariff. This language provides that adjustments to an SCR’s ACL or Provisional ACL are required if a SCR Change of Status has occurred.
Section 5.12.11.1.4: This section entitled “Average Coincident Load of an SCR
Aggregation,” has been re-numbered as section 5.12.11.1.4 to accommodate the new section entitled “Determining a Provisional Average Coincident Load.”

Definitions: Two minor changes have been made to the definitions of “Provisional
Average Coincident Load” and “Average Coincident Load of an SCR Aggregation” to reflect the modifications to the section numbering that occur as a result of this
compliance filing.
III.Effective Date
The NYISO requests an effective date for these tariff amendments of April 11, 2011, which is consistent with the April 11 Letter Order and will allow these tariff provisions to be fully implemented for the Summer 2011 Capability Period.
IV.Service
The NYISO will send an electronic link to this filing 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 electric utility regulatory agency of New
Jersey. In addition, the complete filing will be posted on the NYISO’s website at
