Legal Notification
SHORT DESCRIPTION:
Disclosure of CSA of record DUNS Number in the Find ESI ID Summary Screen
Download
INTENDED AUDIENCE: Retail
Electric Providers
LONG DESCRIPTION: On
October 26, 2009, ERCOT received a MarkeTrak issue from a Market Participant
that indicated the possible disclosure of a Competitive Retailer’s (CR)
DUNS Number with Continuous Service Agreement (CSA) relationship. ERCOT
discovered that the “Find ESI ID” functionality used in Texas
Market Link (TML) provided the CR’s DUNS Number of the CSA on each of the
ESI IDs entered without regard to who is submitting the request when the file
was downloaded by the Market Participant. A DUNS Number may be used to
identify the specific Load Serving Entity assigned to the ESI ID and the CSA
relationship which is considered Protected Information under Section 1.3.1.1 of
the ERCOT Protocols.
The system would query the registration system for the
details of that ESI ID which included a check for the existence of a CR’s
DUNS Number for CSA relationship. The user interface displays
‘yes’ or ‘no’ for that data; however, if a Market
Participant selected the ‘Download Summaries’ button, the detail
file would include the CR’s DUNS Number for the CSA relationship.
At this time, ERCOT does not know how long this problem has existed nor how
many times a CR’s DUNS Number for the CSA relationship was revealed to
another Market Participant.
On October 27, 2009, ERCOT corrected the defect in the
production system with the implementation of an Emergency System Investigation
Request (SIR). Therefore, going forward, if a Market Participant selects
the ‘Download Summaries’ button, the detail file will only provide
a ‘true’ or ‘false’ value and not the CR’s DUNS
Number of the CSA relationship. ERCOT will file a Notice of Protocol
Violation with the Public Utility Commission of Texas (PUCT) in Docket No.
27706.
