Sponsor: J. Aron
Urgent: No
Sections:, Determination of the Counter-Party Future Credit Exposure
Description: Revises the margin adder for Point-to-Point (PTP) Obligations to a value "X" to be determined by the subcommittee process.
Reason: Current margin adder is excessive given the level of risk provided by the market and is well in excess of margin requirements of other markets. For instance, a Congestion Revenue Right (CRR) that is purchased for $0.10/MW will be margined $10.00 in ERCOT ($87,600 annually). That comparable CRR would be margined approximately $0.23 in the New York Independent System Operator (NYISO) market and even less in the Midwest Independent System Operator (MISO) market.
