NOTICE TYPE:  W-A101609-01   Operations

SHORT DESCRIPTION:  Annual Request for Information (RFI) of Summary Disturbance Monitoring Equipment Installations and Summary List of All Available 345 kV Fault Recordings

INTENDED AUDIENCE:  TDSPs and Resource Entities

DAY AFFECTED:  October 31, 2009

LONG DESCRIPTION:  Per Operating Guide 7.1.4, ‘Equipment Reporting Requirements’ and 7.1.2.4 ‘Data Retention and Reporting Requirements’ ERCOT has issued this Market Notice as a RFI of annual summary data to be reported to ERCOT by the owners / operators of Resources and Transmission Services at voltages of 100 kV or greater.

The Texas Regional Entity has in the past initiated this RFI. However, this reporting is now being handed over to ERCOT. ERCOT is sending this standing RFI to ensure Market Participants make their annual report to ERCOT before the deadline of October 31, 2009.

This Notice is being issued shortly before the Operating Guide due date, and some Market Participants have already submitted their 2009 information based on earlier communications through the Reliability and Operations Subcommittee (ROS) working group. ERCOT requests that Transmission / Distribution Service Providers (TDSPs) and Resource Entities who have not already submitted both the Summary Disturbance Monitoring Equipment Installation information and the Summary List of All Available 345 kV Fault Recordings use the attached spreadsheet for submitting the required summary information.

ACTION REQUIRED:  Please submit responses in the attached spreadsheet format and submit to [log in to unmask] by the end of the business day, October 31, 2009. Questions regarding this RFI may be addressed to [log in to unmask].

CONTACT:  If you have any questions, please contact your ERCOT Account Manager. You may also call the general ERCOT Client Services phone number at (512) 248-3900 or contact ERCOT Client Services via e-mail at [log in to unmask].
