M-B020221-01 Issue Identified for Futures Prices used in Forward Adjustment Factors


NOTICE DATE: February 2, 2021

NOTICE TYPE: M-B020221-01 Financial / Credit

SHORT DESCRIPTION: Issue Identified for Futures Prices used in Forward Adjustment Factors

INTENDED AUDIENCE: All Counter-Parties

DAYS AFFECTED: January 30 – 31, 2021

LONG DESCRIPTION: ERCOT has identified a misalignment between ERCOT and Intercontinental Exchange (ICE) systems that impacted the calculation of the Estimated Aggregate Liability (EAL) and Minimum Current Exposure (MCE) components of Total Potential Exposure (TPE) for January 30 – 31, 2021.

TPE determines the amount of Financial Security a Counter-Party (CP) must provide related to its Market activity. Per Protocol Section 16.11.4.3.3, Forward Adjustment Factors, EAL and MCE are adjusted by forward adjustment factors that are based on the ratios of electricity futures prices to historical average ERCOT Real-Time and Day-Ahead prices. The factors as reflected in the calculation are Real-Time Forward Adjustment Factor (RFAF) and Day-Ahead Forward Adjustment Factor (DFAF).

Due to the misalignment, ERCOT did not receive electricity futures prices from ICE for January 30 – 31, 2021. Therefore, in accordance with Section 16.11.4.3.3, ERCOT used the most recently available futures prices (i.e., prices for January 28, 2021) in RFAF and DFAF calculations for January 30 - 31, 2021. ERCOT has implemented a work-around to address the misalignment between ERCOT and ICE. An update will be provided once the issue is resolved. This issue did not trigger any requests for additional Financial Security or result in any breach or default scenarios.

ADDITIONAL INFORMATION: ERCOT will further discuss the issue at the Credit Work Group (CWG) and Market Credit Working Group (MCWG) meeting on February 17, 2021.
