Clarification of EAL

ERCOT Public

ERCOT staff have drafted an NPRR to correct language in the definition of Estimated Aggregate Liability (EAL). Under the existing language, the maximum Initial Estimated Liability (IEL) during the first 40 days of market activity is incorporated in the calculation of EAL indefinitely. The NPRR corrects this to clarify that IEL is utilized only during the first 40-day trading period.
