Approves Repricing Fixed Price TCC Credit Requirement

NYISO’s Business Issues Committee on Wednesday approved using the market clearing price to value and calculate the credit requirement for fixed-price transmission congestion contracts (TCCs).

Sheri Prevratil, NYISO corporate credit manager, told the BIC that the ISO will use $0 as the payment obligation portion of the requirement if the price calculated for the TCC is less than $0, but it will otherwise continue to use the greater of the payment obligation or the credit holding requirement until receiving payment for the contract.

The ISO’s overall TCC credit policy values such contracts for collateral purposes based on the most recent auction price, but the price paid for a fixed-price TCC does not determine the potential credit risk of that contract, she said.

The credit requirement is currently calculated based on the price paid for the TCC, not the market clearing price, and remains the same throughout the duration of the TCC.

If the change is approved by the Management Committee this month and the Board of Directors in March, the ISO will file with FERC in April for deployment in June 2019.
