SHORT DESCRIPTION:
ERCOT’s Disclosure of LSE POSTEDAML Data Cuts
INTENDED AUDIENCE: QSEs
and LSEs
DAY AFFECTED: See Below
LONG DESCRIPTION: ERCOT
inadvertently included a data record labeled “POSTEDAML” in Client
Data Reports (CDRs) posted for Operating Days November 21, 2009, through
January 8, 2010, in some Qualified Scheduling Entity (QSE) files that included
Adjusted Metered Load (AML) data for a Load Serving Entity (LSE) not
represented by that QSE. This is a Nodal data record, which was not intended to
be released to any Market Participant at this. Protocol Sections
1.3.1.1(7) and (9) classify such AML data identifiable to a specific QSE and
LSE as “Protected Information” for 180 days and 365 days
respectively after the applicable Operating Day unless posted on the MIS
pursuant to Section 12. As such, the data was still considered Protected
Information under the ERCOT Protocols when disclosed to other QSEs. ERCOT
has removed all affected files and reposted corrected CDRs for Operating Days
December 27, 2009, through January 8, 2010. Other than the removal of one
erroneous data record, no other data contained in the CDRs was changed.
ADDITIONAL INFORMATION:
CDRs are produced through a manual process. These files are posted for QSEs in
their Miscellaneous folders on Texas Market Link (TML). All data
contained in the CDRs is available in private and public extracts produced by
ERCOT.
With the implementation of the Nodal Market, all data
necessary will be included in extracts and the CDRs will phase out with the
Zonal Market Settlements.
ERCOT will file a Notice of Protocol Violation in PUC Docket
No. 27706, Reports of the Electric Reliability Council of Texas, to
apprise the Commission of this issue.
