I. NYISO OverviewNew York Electric Industry Restructuring

New York Transmission Owners entered into settlement agreements with New York Public Service Commission in mid 1990s which required divesture of generating units

Established phased schedule for retail access

Wholesale markets launched and NYISO began operation on December 1, 1999

III. Real-Time MarketUnique Characteristics

Ex-ante pricing based upon “scheduled” generator basepoint vs. ex-post pricing based upon generator actual output

NYISO uses unit-specific MW signal instead of dollar zonal price signal

Minimum energy bid is -$1000 vs. $0 in PJM. NYISO practice allows market to resolve min-gen scenarios instead of dumping energy

Page 20: Building the Energy Markets of Tomorrow... Today New York State Electricity Markets Federal Energy Regulatory Commission Market Design Technical Conference

Building the Energy Markets of Tomorrow . . . Today

20

III. Real-Time MarketUnique Characteristics (continued)

Variations on criteria used to determine which units are eligible to set Locational Marginal Pricing (LMP)

PJM only allows units that respond to $ zonal price signal to set LMP

NYISO used hybrid pricing method to allow inflexible units to set LMP. PJM does not allow inflexible units to set price

Page 24: Building the Energy Markets of Tomorrow... Today New York State Electricity Markets Federal Energy Regulatory Commission Market Design Technical Conference

Building the Energy Markets of Tomorrow . . . Today

24

IV. Transmission Service MarketsUnique Characteristics

Auction results posted

TCCs settled in Day-Ahead market

May be specified between generators, zones, external proxy buses, NYISO reference bus

Page 27: Building the Energy Markets of Tomorrow... Today New York State Electricity Markets Federal Energy Regulatory Commission Market Design Technical Conference

Building the Energy Markets of Tomorrow . . . Today

27

V. Financial Transmission RightsBenefits

All Transmission Congestion Contracts (TCCs) auctioned except those associated with Grandfathered Transmission Wheeling Agreements

Fully funded TCCs provide hedging certainty

Multiple round auction enhances price discovery

Page 28: Building the Energy Markets of Tomorrow... Today New York State Electricity Markets Federal Energy Regulatory Commission Market Design Technical Conference

Building the Energy Markets of Tomorrow . . . Today

28

V. Financial Transmission RightsBenefits (continued)

“Alternating Current (AC) Power flow” solution provides for improved accuracy

Simultaneous feasibility is assured to avoid “over selling” of Transmission Congestion Contracts (TCCs)

TCCs are “unbundled” - for more liquid market

Moving towards a simultaneous, multi-period TCC auction process by Summer 2003

Reference prices reflect historical accepted competitive offers whenever possible

Process provides for consultation with market participants prior to mitigation

Procedures automated to prevent “lost day”

Mitigation parameters can be reviewed and adjusted over time, allows Market Participants to “build out “ of a congested pocket

Page 41: Building the Energy Markets of Tomorrow... Today New York State Electricity Markets Federal Energy Regulatory Commission Market Design Technical Conference

Building the Energy Markets of Tomorrow . . . Today

41

VIII. Market Monitoring & MitigationUnique Characteristics

NYISO relies on a conduct / impact standard to determine exercise of market power (except for New York City pocket mitigation; plan under development to add conduct / impact plus structural component)

PJM assumes market is un-competitive when transmission congestion exists (except for East/Central/West voltage constraints)

NYISO mitigates to a competitively set reference bid

PJM mitigates via cost-capping (cost + 10 percent)

V. Financial Transmission RightsPerformance Statistics

Net Revenues to Transmission Owners- Year 2000: ~ $260 million

- Year 2001: ~ $65 million

Outstanding Transmission Congestion Contracts (TCCs)- Grandfathered: ~ 40 percent (~ 11,800 MW)

- NYISO Auction: ~ 60 percent (~ 18,800 MW)

V. Financial Transmission RightsPerformance Statistics

Alleviating Contract Path Confusion Parties do not need to optimally pair their

supply and load up as bilateral transactions to minimize transmission charges

TUC paid by aggregator does not depend on how it bids its supply and load

TUC is point-to-point Does not depend on contract path

NYISO exports and wheels to PJM PJM experienced severe voltage problems in the East NYISO experienced depressed SENY voltages Some transactions cut by NYISO to increase voltages PJM requested NYISO voltage reduction to avoid

system voltage collapse NYISO implemented 5 percent voltage reduction to

assist PJM
