NOTICE DATE:  April 30, 2009
NOTICE TYPE:  M-A041509-02 Notice of System Change (PRR)
SHORT DESCRIPTION:  Update on Implementation Details of PRR776
INTENDED AUDIENCE:  Resource Entities and QSEs
DAY AFFECTED:  May 22, 2009
LONG DESCRIPTION:  Protocol Revision Request (PRR) 776, Automatic MCPE Adjustment During Intervals of Non-Spinning Reserve Service Deployment, as approved by the ERCOT Board of Directors, is planned to become effective for the Operating Day of May 22, 2009.  PRR 776 enables a floor price for Market Clearing Price for Energy (MCPE) in Real Time when Non-Spinning Reserve Service (NSRS) is deployed.
ERCOT staff offers a revision to implementation that removes the need to register an additional Resource Entity for the separated virtual Resource that will supply On-line BESCNSRS.  By setting up only a virtual Resource to support On-line BESCNSRS instead of creating two (physical portion as V1 and BESCNSRS qualified portion as V2) the virtual Resource may remain in the existing Resource Entity.  Splitting the telemetry from the associated physical Resource when the virtual Resource is deployed remains the same.  This change will better accommodate all Resource types including Combined Cycle within ERCOT's EMS.
The first Operating Day for PRR 776 is May 22, 2009.  Day Ahead NSRS scheduling with BESCNSRS will commence May 21, 2009.  Entities wishing to supply BESCNSRS with an On-line separate virtual Resource on the first Operating Day must complete registration of the required elements.  ERCOT has extended the date to May 8, 2009, for the PRR776 Resource Asset Registration to be submitted for the database load planned for May 20, 2009.
Once the minimum requirements are completed and verified by ERCOT, the QSE may request from ERCOT a 120 day provisional approval to supply BESCNSRS. The QSE will then be required to pass a quick start test within those 120 days in order to continue to provide this service.
ACTION REQUIRED:  Any Resource Entity (RE) wishing to register a BESCNSRS virtual Resource must submit a PRR 776 Resource Asset Registration Addendum.  The PRR 776 Addendum is attached or may be requested by emailing [log in to unmask]<mailto:[log in to unmask]>.
