Posted 05/02/08: OASIS Development System Availability Only
Effective all day for May 2, 2008 and May 3, 2008, the BPA Transmission Services OASIS Development environment will be undergoing maintenance and testing. The testing process will cause periodic delays processing Transmission Service Request (TSR) submitted over the OASIS development system. During this timeframe, please do not submit more than one or two TSRs at a time over the OASIS Development system.

Posted 04/08/08: Curtailment Manager will be Enabled
At approximately 11:00 PPT on 04/09/2008, BPA Transmission Services Scheduling will resume the use of the Curtailment Manager to implement future hour e-Tag curtailments.

Additionally, the Curtailment Manager will now properly manage Multiple to Multiple (M-to-M) contracts. The change preserves the scheduling flexibility of M-to-M contracts by calculating the Reliability Limits at the Contract Level instead of against each of the M-to-M Transmission Service Requests (TSRs). If a TSR's capacity exceeds the reduced contract capacity, a Reliability Limit will not be placed on TSRs that are part of a M-to-M contract. During a Curtailment, the sum of e-Tag allocations that use part of a M-to-M contract will be curtailed to the reduced Contract Limit as opposed to the individual TSR Reliability Limits.

Until functionality is delivered to automatically e-mail the contract holder stating the reduced contract capacity per path, Transmission Services Real-Time Schedulers will call M-to-M contracts holders when a Reliability Limit is placed on those contracts.

Posted 04/04/08: ETS Tagging System Outage Planned for 4/8/2008
Effective 00:15 PPT on 4/8/2008, OATI will be taking their ETS tagging system down for up to 30 minutes as part of a hardware upgrade. During this outage, tag processing and all tag authority service distributions for OATI tagging customers will be disabled. Reservation request processing will not be affected by this outage.

Posted 03/26/08: 2008 Network Open Season Notice
In preparation for the upcoming 2008 Network Open Season (NOS), Transmission Services will, effective immediately, make offers of all long-term network segment transmission service in the form of Precedent Transmission Service Agreements (PTSA). This action is being taken in order for Transmission Services to effectively transition to NOS, including the preparation of a PTSA for every network Transmission Service Request (TSR) in the long-term transmission request queue. For additional key information concerning the upcoming 2008 Network Open Season, see 2008 Network Open Season Notice.

Posted 1/25/08: STF Competition Market Activated for Testing Purposes
Transmission Services has turned on the STF Competition Market today for Hourly Firm, Daily Firm, Weekly Firm and Monthly Firm in the Development environment for testing purposes only. Customers submitting requests for these products should expect to see competition notifications where applicable.

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.

OASIS ATC Notes
The ATC margin documented in the posted related ATC Methodology document as "ATC Methodology Margin" (AMM) will be posted in the OASIS field labeled "Transmission Reliability Margin" (TRM). Rounding is applied to the displayed path MW values posted in OASIS Sys Data. For additional details see, OASIS ATC Notes.

BPA Transmission Services determines Long-Term Firm (LTF) Available Transfer Capability (ATC) values assuming all lines are and will be in service. The firm ATC values currently posted on the BPA Transmission Services OASIS site include Total Transfer Capability (TTC) reductions for planned outages. These TTC reductions do not affect LTF ATC. As a result, the LTF ATC and TTC values posted on OASIS are lower than actual values used in LTF ATC evaluations. The Short-Term Firm ATC and TTC values posted on OASIS are accurate.
