Posted 09/02/10:   Moving TS webSchedular and webTrans to new servers
On September 28, 2010 from 6:50 AM - 7:10 AM PDT, Transmission Service will be moving their internal system, webSchedular and webTrans, to new servers. TSR's and E-tag's may experience a delay in being processed during this time and customers may not be able to access CDE. TSR's and E-tag's will queue up and resume processing after the conversion. We apologize for the inconvenience this may cause.

Posted 09/02/10:   CDE for Ancillary Services Notification
On September 28, 2010 at 1:00 PM PDT, CWI will no longer be supported. Customers must then submit/review data using CDE.

Originally Posted 03/31/10: CDE for Ancillary Services Notification Over the past month Transmission Services has been working to address the issues identified with CDE for Ancillary Services. We have made the decision to delay the full implementation of this application until the issues have been resolved. In the interim the Ancillary Services function of CDE will continue to run in parallel with CWI. Customers are encouraged to continue to work with the CDE environment and identify any outstanding issues.

Posted 09/02/10:   Network Maintenance Planned

Posted 08/16/10:   2010 NOS Opt Out Studies
BPA is offering system impact study agreements for specific transmission service requests which opted out of the 2010 Network Open Season (NOS). More Information

Posted 08/10/10:   OASIS Points Deactivation
Effective immediately, BPA Transmission Services would like to inform its customers that the following may not be used as OASIS points when requesting transmission service on BPA Transmission Service's OASIS:

• USCNDNBDRE230
• NELWAY230
• WANETA230

Transmission Services is in the process of deactivating these points in its OASIS because customers cannot currently schedule to or from these points. Until these points are deactivated in OASIS, any TSR using them will be deemed INVALID by Transmission Services. BPA is continuing to develop its long-term approach regarding the potential creation of an eastside scheduling point for the BC-US border.

Customers may continue to use "USCNDNBDRW500" and "USCNDNBDRCNTGS" for requesting transmission service on the west side of the Northern Intertie. If you have any questions, please contact the Reservation Desk at (360) 418-8499.

Posted 06/30/10:   COI Emergency Outage
At 1146 BPA took an emergency outage on the Sycan 500kV Series Capacitors Group 3 on the Summer Lake - Malin 1 500kV line, the emergency outage is due to a loss of a power supply impacting relay and protection. The estimated time for returning the facilities to service is 1900 today but subject to change. Please see OASIS under the Notices button, and then click Message or WECCNET for the most up-to-date information.

The COI N-S SOL is dynamic and currently at 4225MW due to the outage and additional reductions from Hemingway - Summer Lake flows. Actual flows on the COI are currently below the SOL, and curtailments have not been required. If the COI N-S SOL is exceeded before the facilities are returned to service, the mitigation process could require curtailments.

Posted 06/17/10:   Transmission Service Requests Redirect Issues
Multiple redirect Transmission Service Requests (TSRs) submitted with the same related ref # (parent) and at approximately the same queue time may result in one of two situations that can be problematic. More Information

Posted 05/21/10:   Outages on West of Cascades North Path
Since May 18, BPA has experienced outages that affect the West of Cascades North Path and significantly reduced the path System Operating Limit (SOL), E>W, below seasonal levels. The reduction is primarily due to an outage on the Olympia-Grand Coulee 1 287kV Line, which was extended after a planned outage to repair a safety problem. An additional planned outage on the Echo Lake-Monroe 1 500 kV line for spacer damper work and danger tree maintenance also contributes to the reduction.

Curtailments were implemented on May 18 in multiple hours and for one hour on May 19 to reduce power flows below the SOL level in those hours. In addition, BPA redispatched the FCRPS. Because BPA expected power flows would continue exceeding the path SOL levels, BPA implemented measures to limit new hourly sales affecting the path. Due to new studied conditions, BPA is able to increase the path SOL and lift the sales limit, effective immediately. Please contact your Transmission AE for more information.

Posted 05/13/10:  TSR Processing Slowdown Follow-Up
Over the past few weeks, large numbers of redundant TSRs submitted prior to and shortly after the 10:00 market opening have significantly slowed TSR processing. Please note that the clock at the upper right corner of the OASIS window determines the queue time of TSRs as they are submitted. TSRs for the next WECC pre-schedule day(s), with a queue time prior to the market opening, will be given the status of INVALID.

In addition, there is no advantage to submitting multiple identical requests after the market opening. If ATC is not available for the first TSR submitted, all subsequent TSRs for the same POR/POD and for the same MWs will yield the same result. To avoid next hour requests being caught up in busy market opening periods, we encourage transmission service requests for the next hour to be submitted as early as possible and ahead of the market opening period when possible.

Posted 04/23/10:  Accessing CDE
Over the past month, a number of problems have been reported with CDE that are particular to the 4.1 User Interface. Transmission Service strongly recommends that you access CDE using the 3.8 User Interface. By doing so, problems with CDE will be greatly reduced. To access the 3.8 User Interface, click the link below the login section of the screen that says, Switch to webTrans 3.8 UI.

Posted 04/14/10:  In Hour Curtailment Postings
Effective May 1, 2010, Transmission Services will post all in-hour curtailments in OASIS Notices using the Messages category "Curtailments". These postings will include the time and date of curtailment and the path/flowgate.

Posted 03/03/10:  Curtailment Manager Update
Effective March 9, 2010 at 0900 (HE 10) Transmission Services will resume using Curtailment Manager (CM) for next-hour e-Tag Curtailments for all Interties and External Interconnections. Curtailment Wizard will continue to be used on Interties and External Interconnections for in-hour except for West of Hatwai and West of Garrison. Curtailment Manager will continue to be used to curtail West of Hatwai and West of Garrison for in-hour. This is due to a limitation in Curtailment Wizard in handling the complexities of POR and POD combinations across these paths. More Information

Posted 05/23/08:  OASIS Displaying Pending Non-Firm ATC Values
On May 23, 2008 14:18 PPT, it was determined that the Non-Firm ATC values posted in the Non-Firm ATC column of the System Data Summary in OASIS is displaying Pending ATC values instead of Confirmed ATC values as specified in the FERC S&CP. OATI is currently working to correct this issue.

Posted 7/13/07:  OASIS Temporary Suspension of Short-Term Firm Competition Market
Transmission Services discovered an issue with how the wesTTrans OASIS system (OASIS) implemented the competition rules for initiating competitions for the Short-Term Firm (STF) Market (see discretionary log #43708 posted on OASIS). As a result, Transmission Services has temporarily suspended STF competition and is currently working diligently with OATI to provide a solution that would allow OASIS to correctly perform STF competitions. STF requests will continue to be processed over OASIS. The suspension applies only to the competition aspect of STF ATC evaluations.
