Re: ISO New England Inc. and New England Power Pool; Docket ER12-1155-000;
Errata to Intervention
Dear Ms. Bose:
On March 16, 2012, the New York Independent System Operator, Inc. (“NYISO”)
moved to intervene and comment in support of the February 24, 2012 tariff filing made by ISO New England, Inc. and the New England Power Pool in the above-captioned proceeding.
The NYISO respectfully resubmits its Motion to Intervene and Comment to correct a
ministerial error in the original caption. The NYISO inadvertently identified the matter in ER12-
1155-000 as a NYISO matter whereas it is an ISO New England, Inc. and New England Power Pool matter. The NYISO respectfully requests that the Commission accept this resubmitted
Motion to Intervene and Comment as an erratum to the NYISO’s March 16th motion.
Please do not hesitate to contact the undersigned should you have any questions.
Respectfully submitted,
/s/Mollie Lampi

BEFORE THE
FEDERAL ENERGY REGULATORY COMMISSION
ISO New England Inc. and)Docket No. ER12-1155-000
New England Power Pool)
MOTION TO INTERVENE AND COMMENTS IN SUPPORT BY
THE NEW YORK INDEPENDENT SYSTEM OPERATOR, INC.
Pursuant to Rules 212 and 214 of the Federal Energy Regulatory Commission’s
(“Commission”) Rules of Practice and Procedure, 18 C.F.R. §§ 385.212, 385.214 (2011), the
New York Independent System Operator, Inc. (“NYISO”) moves to intervene and comment in
support of the February 24, 2012 tariff filing by ISO New England (“ISO-NE”) and the New
England Power Pool (“NEPOOL”) (together the “Filing Parties”) in the above-captioned
proceeding.1 As discussed below, the Filing Parties have proposed to amend the ISO-NE
Transmission, Markets and Services Tariff by adding a set of market rules known as Coordinated
Transaction Scheduling (“CTS”). CTS is designed to enhance the efficiency of energy trading
over ISO-NE’s external border with New York and, once in place, is expected to significantly
lower the cost of energy for market participants in both the ISO-NE and the NYISO regions.
The NYISO supports this filing and urges the Commission to approve it.

II.COMMENTS
The Filing Parties propose to implement CTS to improve the efficiency of external
energy transactions with the NYISO.2 The NYISO filed companion amendments to its tariffs on December 28, 2011.3
The NYISO agrees with the Filing Parties that CTS can be expected to reduce customers’
energy expenditures in both regions by $100 million or more annually.4 These savings originate
in two results expected from CTS implementation - an increase in the utilization of existing
transmission capacity to move energy more often from the lower price region to the higher price
region and a reduction in the utilization of transmission capacity for counter-intuitive flows or

As the Filing Parties explain, CTS is proposed to be implemented initially at two interconnection points
with New York - the New York Northern AC interface and the Northport-Norwalk interconnection. NE Filing at
p. 3. See also: NYISO Filing at p. 1

Transaction Scheduling Market Rules and Request for Waiver Docket ER12-701-000 (filed Dec. 28, 2011)
(“NYISO Filing”). Once CTS is approved, the NYISO expects to expand the use of CTS to transactions at several interconnection points with its other neighbors, such as PJM, through further tariff filings over the next several years. NYISO Filing at fn 25.

See the estimate in savings of between $387 million and $417 million over a three-year period. NE Filing
at p. 9. This estimate, also referenced in the NYISO Filing at p. 4 and Attachment VI, was developed by the ISO-
NE External Market Monitor, Potomac Economics, which also serves as the NYISO Market Monitoring Unit.

trades from the higher cost region to the lower cost region.5 Increased transmission capacity
utilization will lower the combined cost of generation in the two regions by further displacing
higher cost generation in one region with lower-cost generation from the other. Reducing
counter-intuitive flows will avoid schedules between the regions that require the exporting region to increase production from higher-cost resources while simultaneously causing the importing region to displace lower cost generation.6
These CTS-based improvements in external transactions are vital as the existing
inefficiencies on the system are fairly prevalent. As the Filing Parties explain, data suggests that ISO-NE and the NYISO (“the ISOs”) are currently scheduling power from the high-cost region to the low cost region 44 percent of the time.7 To support these counter-intuitive trades, as
mentioned, the exporting region must increase production from higher-cost resources while,
simultaneously, the importing region must displace lower cost generation. Even when power is moving efficiently from the low-cost to the high-cost region, the data also suggest that
significant transmission capacity is left unused. Until remedied, these inefficiencies leave the production cost savings that can be reasonably expected from efficient external transactions
unrealized and unavailable to the ISOs’ market participants.
The ISOs still have work to do but both expect to be ready to implement this new market
design sometime towards the end of 2013 or the first half of 2014.8 The NYISO encourages the
Commission to consider the Filing Parties’ submission in this docket and the NYISO’s CTS

filing in ER12-701-000 concurrently and to issue Orders accepting the tariff revisions for both regions within sixty days of this filing - April 24, 2012.
III.MOTION TO INTERVENE
The NYISO, the balancing authority and transmission grid operator for the New York
Control Area, administers market rules for exporting and importing energy from ISO-NE. It has
filed substantially similar tariff amendments with the Commission in order to allow it and ISO-
NE to implement CTS in their Control Areas simultaneously.9 However, it cannot implement its
market rule enhancements without concurrent implementation by ISO-NE. The NYISO,
therefore, has a direct and substantial interest in the Commission’s decision in this proceeding,
which no other party can adequately represent. Accordingly, it is in the public interest to permit
this intervention.
IV.CONCLUSION
For the reasons stated herein, the NYISO asks the Commission to grant its motion to intervene and to grant the relief described herein.
