PRR/SCR
CLASSIFICATION: Public
SHORT DESCRIPTION: Clarified Implementation of PRR763,
Use
of WGRPP as Planned Operating Level in Day-Ahead Resource Plan for
WGRs.
INTENDED AUDIENCE: QSE Operations and Wind Resource
Entity Personnel
DAY AFFECTED: Operating Day July 1,
2008
LONG DESCRIPTION: In accordance
with Protocol Revision Request (PRR) 763, ERCOT will begin using Wind-powered
Generation Production Potential (WGRPP) as the planned operating level in
Resource Plans for Wind-powered Generation Resources (WGRs) starting with
Operating Day July 1, 2008. ERCOT
will use a forecasting service to provide the WGRPP
forecast to each QSE representing WGRs via email on an hourly basis. Each forecast covers a rolling 48-hour
period.
ACTION REQUIRED:
Starting with
the June 30, 2008 Day-Ahead activities for Operating Day July 1, 2008, QSEs
representing WGRs must use the most current WGRPP forecast in Resource Plan
submittals prior to the Day-Ahead Replacement Reserve Service (RPRS) market for
Operating Day July 1, 2008.
After the close of the
Day-Ahead RPRS Market, QSEs representing WGRs shall update their Resource Plans
and schedules to reflect the expected wind-powered generation production. Beginning September 1, 2008, QSEs shall
update Resource Plans using WGRPP forecasts upon receiving notice from ERCOT for
an Adjustment Period RPRS Market.
DAY-AHEAD: QSEs representing WGRs must use the
WGRPP forecast as the planned operating level in the Day-Ahead Resource Plan
submitted for input into the Day-Ahead RPRS procurement study. QSEs must use the WGRPP forecast closest to
the time the QSE submits the Resource Plan before 1600 hours.
HOUR-AHEAD: Beginning September 1, 2008, if ERCOT
must procure additional RPRS during the Adjustment Period (pursuant to ERCOT
Protocol Section 6.6.3.2.1, Specific Procurement Process Requirements for
Replacement Reserve Service in the Adjustment Period), QSEs representing WGRs must update (with
the latest emailed forecast) the forecasted WGRPP for the Operating Hour that
energy from the RPRS Resources is required. QSEs must use, the most current WGRPP
forecast to update their WGR
Resource Plans for the Adjustment Period RPRS Market. (Note: this Hour-Ahead
portion will not be implemented until September 1, 2008 in order to allow QSEs
to change their automated intra-day processes)
QSEs
representing WGRs must confirm with ERCOT the email address they wish to use to
receive the hourly WGRPP
forecast. QSEs must send the
preferred email address to their ERCOT Account Manager or to [log in to unmask]
by Noon on June 26, 2008. The forecasting service provider will
begin sending WGRPP forecast emails upon installation of email address into an
automated email system.
ADDITIONAL INFORMATION: An Operations
Bulletin will be distributed with a Notice and posted on ERCOT.com. The bulletin will provide more detail
including transitioning new WGRs into this
procedure.
ERCOT will implement posting of aggregate WGRPP forecasts to its web
site as soon as possible. A Notice
will be issued to affected Market Participants when this posting
begins.
A teleconference is scheduled for 10:00 CPT on June 30, 2008 for QSEs
and Resource Entities to ask questions prior to the first RPRS procurement study
at 1600 for Operating Day July 1, 2008.
