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
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].
