NOTICE DATE: April 15, 2009
NOTICE TYPE: M-A041509-01 Notice of System Change
(PRR)
SHORT DESCRIPTION: 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, was
approved by the ERCOT Board of Directors on March 17, 2009. PRR776
enables a floor
price for Market Clearing Price for Energy (MCPE) in Real Time when Non-Spinning
Reserve Service (NSRS) is deployed.
This PRR creates two types of
NSRS: (1) 30MNSRS (30 minute Non-Spinning Reserve Service); and (2) BESCNSRS
(Balancing Energy Service Capable NSRS). 30MNSRS must be provided by Off-line
Resources. BESCNSRS
may
be provided by a registered, separate virtual Resource (in accordance with
Section 10.3.2.1, Generation Meter Splitting) that is “On-line” and capable of
being ramped to a specific output level within 15 minutes for NSRS and through
Balancing Energy Services.
The
first Operating Day for PRR776 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 by May 1, 2009, in order to be included in the database load. 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 create
a new Resource Entity with a QSE Acknowledgement and submit a PRR776 Resource
Asset Registration Addendum. To
request the PRR776 Addendum, please send an email to [log in to unmask].
