PRR814

This Protocol Revision Request (PRR) establishes a definition for NOx Emissions Allowance Index Price (NOxEAIP) that relies on a published cost index for NOx emissions allowances.  The PRR provides Qualified Scheduling Entities (QSEs) with an option to either provide detailed documentation of the actual cost of NOx emissions allowances as part of the verifiable cost process or to rely on the NOxEAIP.  Specifically, this PRR allows QSEs to recover the cost of emissions allowances when providing Replacement Reserve, Out of Merit Capacity (OOMC) or Out of Merit Energy (OOME) Service as directed by ERCOT if the costs of those emissions allowances are less than one hundred ten percent (110%) of the NOxEAIP.  This is the same concept that is applied to the documentation requirements of natural gas prices and fuel oil prices for verifiable cost purposes.  This PRR also adds language to clarify how QSEs can recover any emissions-related costs for both startup and operations when providing Replacement Reserve, OOMC or OOME Service.

This PRR also proposes non-substantive administrative changes, such as correcting acronym and defined term usage and section references.  These are shown below with the author “ERCOT Market Rules.”
