1 Energy and Bilateral Transactions Tariff Review Robert Pike Director, Market Design New York Independent System Operator Market Issues Working Group February 25, 2010

2 Overview The NYISO is identifying inconsistencies, ambiguities, and outdated material in the NYISO s Tariffs and proposing amended tariff language to resolve them. This presentation proposes changes to the energy and bilateral transaction provisions of the OATT and Services Tariffs, covering the market rules associated with bidding, scheduling and settlement of energy and bilateral transactions. These proposed changes are primarily ministerial; exceptions requiring software revisions are noted in this presentation. 2

5 Schedule To MIWG on February 25, 2010 for overview of scope and content of revisions. Utilize March MIWG meetings for more detailed review of sections with significant revisions: Energy Market MST: Article 4 Bilateral Transaction MST: Attachment B, OATT: Part II Request feedback/comments on remaining changes and/or desire for additional detailed reviews of changes. 5

6 Definitions Clarifications: Compensable Overgeneration, Minimum Generation Bid, Normal Upper Operating Limit (UOL N ), Out-of-Merit Generation, Point(s) of Withdrawal, Real-Time Bid New: Real-Time Scheduling Window Defines the timing of the market close for the real-time market. Established to simplify tariff reference to the time period. Removed: Scheduling Differential Defined the threshold economic difference applied to prescheduled transactions to differentiate schedule types 6

7 Pre-Scheduled Transaction Recommending the removal of the capability to schedule transaction in advance of the Day-Ahead Market ( Pre-Schedule ). Pre-Schedule Transaction allows participate to request transmission service in advance of the day-ahead market. Schedule evaluated against available ATC and ramp. Bids assigned the highest economic priority (±$1000) when evaluated in SCUC or RTC. Pre-Scheduled transactions have been utilized on only five occasions since inception (2 rejected, 3 accepted) Last usage in April 2007 (only time since SMD2) Market Participant has indicated they are not likely to use the feature again. 7

8 Pre-Scheduled Transaction Eliminate the ongoing maintenance and support costs of the product. Enhanced Interregional Transaction Coordination will involve a significant overhaul of transaction processing software. Eliminating pre-scheduled transaction will reduce implementation costs and efforts. Does not realistically impede the ability to place the highest economic priority on a transaction bid to ensure schedules are achieved. No incremental functionality available through the use of the product. These tariff amendments comprehensively remove references to the product. 8
