Posted 06/25/09:  Conversion to Sys Data V 1.5 in OASIS Release 3.4.10
Effective June 30, 2009 at approximately 08:10 AM PD, the production environment of wesTTrans OASIS will be upgraded to version 3.4.10. The OASIS Sys Data display where TTC and ATC values are posted in OASIS will be unavailable for a short period of time during the conversion. After this brief outage, the Sys Data GUI will be in the version 1.5 format. OASIS will continue to support the systemdata template requirements of S&CP V1.4. Customers' internal systems may be impacted.

See further details on the Transmission Services site. Submit questions or concerns to etag@bpa.gov.

Posted 06/18/09:  Removal of incorrect OASIS Source/Sink: Garrison500
Effective immediately, the GARRISON500 OASIS Source/Sink related to BPAT.NWMT is unreservable. To submit TSRs for Long--Term service or exercise renewal rights to NWMT, use GARRISON230 Source/Sink. To submit TSR's for Long-Term service or exercise renewal rights to BPAT's Montana Intertie, use GARRISON500CLS Source/Sink. This change reflects the fact that BPAT has no 500 kV connection to NWMT at Garrison Substation. Existing Confirmed TSRs with this Source/Sink are still valid. Customers with pending TSRs will be contacted to conform the TSR if an offer is made to either GARRISON230 or GARRISON500CLS.

Posted 06/12/09:  Dynamic e-Schedules assigning to incorrect TSRs
Dynamic e-Schedule's demand may be inappropriately assigned to unrelated TSRs resulting in incorrect blanket demand failures. Transmission Services is working with the vendor to resolve this issue. Transmission Services will post an update when the issue is resolved.

Posted 06/05/09:  Problems with e-Tag blanket functionality
Transmission Services is experiencing issues with its e-Tag blanket functionality used during the scheduling process. The e-Tag Blanket Demand/Capacity check may allow customers to over schedule their transmission rights. We advise customers to monitor their rights during the scheduling process. If you suspect that the blanket functionality is not working, reference a specific TSR rather than the contract number in the e-Tag's OASIS field. We are working with the vendor to resolve the issue.

Posted 05/27/09:  Tagging Protocol for Transactions through Hot Springs
Effective June 1, 2009, Avista, BPA, Idaho Power, NorthWestern and Pacificorp have agreed to implement new capacity management procedures associated with the Hot Springs POR/POD, the Amps Line, and the Montana-to-Northwest Path. For more information refer to the related posting on the Transmission Services web site.

Posted 05/19/09:  OASIS Source Change: USCNDNBDRW500
Effective immediately, USCNDNBDRW500 is the OASIS Source/Sink for BC.US.BORDER POR/POD, replacing USCNDNBDRW230 when submitting TSRs for long-term service or exercising renewal rights. This change corrects the voltage designation for the existing Source/Sink. Existing Confirmed TSRs with this Source/Sink are still valid. Customers with pending TSRs will be contacted to conform the TSR if an offer is made.

Posted 05/08/09:  Curtailment Manager
Effective immediately, Transmission Services is discontinuing the use of Curtailment Manager for next-hour e-Tag Curtailments for all Interties and External Interconnections due to a system issue. Curtailment Manager will continue to be used to send Reliability Limit notifications on TSRs. OATI’s Curtailment Wizard will be used to curtail in-hour and next-hour e-Tags. Next hour Non-Firm e-Tags will be curtailed Last-In-First-Out (LIFO) based on the e-Tag submittal time. All Firm e-Tags will be curtailed Pro-Rata. Transmission Services is working with the vendor to resolve this system issue.

Posted 04/24/2009  Curtailments on SOA and NOH S>N
At times, BPAT experiences high flows that affect the reliability of the South of Allston (SOA) and North of Hanford (NOH) flowgates in the South-to-North direction. Currently, BPAT manages sales on SOA and NOH in a North-to-South direction only. BPAT is developing modifications to ATC Methodologies and tools to add the South-to-North direction Flowgates. In the interim, BPAT will publish associated planned outages to OASIS Messages and real-time events to the Transmission System Events page. Also, BPAT will follow flowgate-based procedures on the SOA and NOH paths in the South-to-North direction to relieve congestion as necessary. For more information see the Network Congestion Validation bulletin and the Redispatch and Curtailment Procedures posted at http://www.transmission.bpa.gov/Business/Business_Practices/default.cfm

Posted 04/08/2009  Problem with Resales
Due to the OASIS 3.4.09 software upgrade this morning it appears there are some cases where profiled Resales are not successfully processing. A temporary workaround is to create multiple Resale TSR's that contain contiguous hours of each part of the profile where necessary. BPAT is working with our OASIS vendor to fix the issue as soon as possible.

Posted 02/19/09:  OASIS Source Change: BIGEDDYCNTGS
Effective immediately, BIGEDDYCNTGS is the OASIS Source/Sink for BIGEDDY POR/POD when submitting TSRs for long-term service or exercising renewal rights. This change incorporates BIGEDDY230CELO and BIGEDDY500CELO into one Source/Sink. Existing Confirmed TSRs with these points are valid. Customers with pending TSRs will be contacted to conform the TSR if an offer is made.
