NPRR345 EILS Availability Calculation Post-Depletion
ReasonThe current Protocols do not contemplate the exclusion of hours following depletion of the 8-hour EILS performance obligation for purposes of calculating the availability performance metric, and the "EMERGENCY INTERRUPTIBLE LOAD SERVICE Technical Requirements & Scope of Work" document currently specifies a method of calculating availability that is inconsistent with the Protocols and can produce a highly inequitable result. This NPRR resolves this dilemma by providing that after successfully meeting either the two deployment or 8 hour interruption event performance requirements, a Load’s availability factor will be set at the higher of 100% or the availability factor calculated by ERCOT, allowing for the EILS Load to be measured on its event performance factor only.
