RARF Addendum
Information / QnA Session
Dana Showalter
January 10, 2008
Addendum Summary
• Send dates:
– Addendum and Guide sent to Resource Entity Authorized
Representatives between January 4 and January 10
– If no addendum received, most likely a problem with the RARF
submitted on Nov 9
– Contact [email protected] with questions or to
request the addendum
• Due to ERCOT on January 31
– Send to [email protected] or submit via TML
• Column A
– Only “new fields” will be read into the database
– Any “existing” fields will continue to be read into the database off
of the RARF
2
Important Information (from Guide)
• The purpose is to gather additional planning data for EDS 4
RARF
• The Addendum has locked fields – these are typically
information gathered from the RARF and used as reference.
Corrections to these fields should be made on the RARF itself
• All data in this addendum is unit or site specific. No CC train or
CC configuration information is included nor requested
• For both the RARF and the Addendum, the unit and site codes
should not be changed, as these correlate to existing codes
used in ERCOT systems
• Pre-populated fields contain data from RARFs received prior to
December 18, 2007
3
Important Information (continued)
• Why do Resource Entities need to fill out this Addendum and
correct the RARF?
– In order to avoid manual data corrections in the database, each
field (row) of the RARF and addendum are only read into the
database from one form. If the field is on the RARF – it will
continue to be read from the RARF. Only new fields identified on
the Addendum will be read into the ERCOT database. This helps
with quality control and limits manual loading of information.

Additional Assets Addendum – Why?
5
Additional Assets Addendum
• ERCOT Branch Data can assist with filling this out
– Found in Operations Model Data folder on secure Operations
and System Planning Website
– http://oldercot.ercot.com/tmaps/login.cfm
• TSP will be familiar with naming conventions and may be able
to provide assistance
• Additional questions should be directed to
[email protected] who will redirect to ERCOT
planning

Private Use Network Addendum
• Should only be on Addendums for PUN Resources
• Site and unit information requested
• Site information includes:
– Totals of MWs, MVARs
– Totals of Gross Generation, Average Load, and Average Net to
grid
• Injection (positive) OR consumption (negative)
– Load characteristics (in %, should add to 100% for MW and
100% for MVAR)
• Unit information includes:
– Allocating the MWs and MVARs across the units (should sum up
to site totals)
– Unit trip information

Private Use Network Addendum – Site Information
•
•
•
Enter totals for site (all units represented on RARF)
Please note that these values should be gross generation and load and only net
values for specific rows.
A simple check would be: Net Interchange = Gross Capability – Self Serve Load

Gen and CC Addendum Error
• MW and MVAR values are swapped on Addendum only
– Values in database correspond to values on RARF
– No changes needed due to this mis-population as it was
provided for reference only
• To avoid in future
– Test load with column name, which can be verified against RARF
field
11
Gen and CC Addendum
•
•
Please ensure we get four ratings – the generator nameplate ratings in
MVA, MW, and MVAR and the turbine rating in MW.
Please note the nameplate ratings should correspond to a nameplate
power factor.
– New: Turbine Rating (MW)
– Renamed: Generator Name Plate Rating (MVA)
– Corrected: label error noted in previous WebEx conversations where
Rating (MVA) was used for reactive power. Please check this and
correct on RARF if needed.

Gen and CC Addendum

•
The two sections pictured below are omissions from the RARF.
The voltage connection is needed for the step up transformer and was
originally requested on the Generation Data Forms.
As noted in previous WebEx sessions, details about the total unit
auxiliary load were missing.
– The auxiliary load characteristics should be completed on the RARF for
each unit in percentage of total aux load.
– The percentages should add up to 100%, as it is allocating the total aux
load that will now associated with the generator with these new fields.

RARF Update
• To protect database integrity
– RARFs must be submitted by Resource Entity
– DUNs numbers of entities (submitting and owners) must align
with proper entity
– General Information tab must be complete
– Resource Entities are being asked to clarify this information if
conflicts exist
• Additional RARF corrections may be requested as more data is
applied to ERCOT Nodal Systems
– Every attempt will be made to clearly state what needs corrected
and why (i.e. if the field requires KV and 138000 is entered)
– RARF will need to be corrected on the RE end and submitted to
ERCOT to keep the database matching the currently submitted
RARF (the process will be after the certified RARF)
– Working together we can get the most complete, accurate RARF
• Internal effort by Registration Team to encourage data is being
validated by systems proactively.
17
RARF Update
• Scorecards will be updated with RARF data – Target Date
January 18, 2008
• TPTF Update during the January 21-23, 2008 meeting will
identify upcoming dates and events
• Combined Cycle units may have a forthcoming addendum
• Resource Entities that have not submitted RARFs will be
identified at the February, 2008 TAC meeting
