NOTICE DATE:  November 24, 2010

NOTICE TYPE:  W-A112410-01 Settlements

SHORT DESCRIPTION:  Payment due on Private WAN Fees

INTENDED AUDIENCE:  Market Participants with an executed ERCOT WAN Agreement

DAY AFFECTED:  December 24, 2010

LONG DESCRIPTION:  The ERCOT Wide Area Network (WAN) provides an interface for data transfer between Market Participants (MPs) and ERCOT. Pursuant to the ERCOT WAN Agreement, MPs are required to reimburse ERCOT’s cost of performing or acquiring WAN services on a monthly basis. ERCOT has posted the WAN invoice for each entity who should receive one in that entity’s folder on the Texas Market Link (TML) in a folder marked MISCELLANEOUS.

This is the last time these files will be posted on TML. All future WAN invoices will be posted on the Market Information System (MIS). To provide the ability to test your access to the MIS, these invoices are also being posted on the MIS, which still requires a digital certificate. You can find the invoices under Services/ERO and WAN Invoices:

https://mis.ercot.com/pps/tibco/mis/Pages/Services/Home.

ACTION REQUIRED:  The WAN Invoice issued November 24, 2010, is due December 24, 2010. Please remit payment for any WAN Invoices due by December 24, 2010.

ADDITIONAL INFORMATION:  The MISCELLANEOUS folder is found in the TML list of folders. Access to this folder will require a Digital Certificate with the “Reports” role assigned. If you do not already have a Digital Certificate and require access, please contact your company’s User Security Administrator (USA). All files posted to the MISCELLANEOUS folder will remain visible for 30 days before rolling off.
