    Posted 5/7/14:   BPAT Systems Maintenance
    BPAT's e-Tag and OASIS software vendor will be performing system maintenance on 05/20/14, from 05:00 to 06:00 (PPT). It is expected that there will be a few minutes of interruption to all OATI services during that time frame. We apologize for any inconvenience this may cause.

    Posted 5/2/14:   Effective Immediately - OASIS Reservation Points Suspended
    Until further notice, BPA Transmission Services (BPAT) is suspending use of the following OASIS reservation points in the long-term market as a "source" for new long-term original transmission service requests on BPA's system:

    • RKYRCH230
    • RKYRCH230MIDCR
    • VALHALA115
    • VALHALA115DOPD
    • VALHALA115MIDC

    During this time, BPAT will invalidate original long-term requests submitted using these points as a source. BPAT will continue processing redirect, reassignment and rollover requests identifying one of these points as a source when the parent reservation uses the point as a source.

    BPA does not currently have the ability to provide additional long-term service from these points and needs to further consider the policies and agreements regarding service at these points before it can accept additional original long-term requests. BPAT is evaluating potential solutions. Once BPAT implements a solution, it will issue another notice that customers can again submit long-term requests using these points as a source.

    Other Mid-Columbia area points, including the points associated with the Columbia, Sickler, Vantage, and Midway substations, remain available for use as a source. If you have any questions, please contact the Reservation Desk at (360) 418-8499.

    Posted 4/30/14:   BPA Announces Completion of 2013 Cluster Study

    BPA Transmission Services will issue the Cluster Study Report to Customers with requests in the study in advance of this meeting.

    For immediate questions, please correspond with your transmission account executive or submit your query via email to techforum@bpa.gov with "2013 Cluster Study" in the subject line.

    Posted 4/23/14:   BPAT Systems Maintenance

    Posted 4/2/14:   Transmission Reassignment Reporting Requirement
    This notice serves as a reminder to transmission customers of the obligation to accurately report information associated with transmission capacity reassignments, including but not limited to pricing information, on BPA's Open Access Same-Time Information System (OASIS). Customers reassigning transmission scheduling rights (Resellers) are required to report all reassignments on BPA's OASIS as per section 23.3 of BPA's tariff and section A.2 of BPA's Resale of Transmission Service Business Practice, v.10. Failure to report this information accurately can potentially lead to criminal sanctions under 18 U.S.C. § 1001, which makes it a crime for any person knowingly and willingly to make to any Agency or Department of the United States any false, fictitious or fraudulent statements.

    Pursuant to section 220 of the Federal Power Act, 16 U.S.C. § 824t, and Federal Energy Regulatory Commission (Commission) Order No. 768, BPA will begin filing capacity reassignment information in Electric Quarterly Reports (EQR) with the Commission in April of 2014. BPA will not be responsible for the accuracy of the information. If the Commission has questions regarding the accuracy of the information reported by the Reseller on BPA's OASIS, BPA will refer the Commission to the Reseller.

    Posted 4/2/14:   BPAT Systems Maintenance
    BPAT's e-Tag and OASIS software vendor will be performing system maintenance on 04/15/14, from 17:00 to 18:00 (PPT). It is expected that there will be a few minutes of interruption to all OATI services during that time frame. We apologize for any inconvenience this may cause.

    Posted 06/17/10:   Transmission Service Requests Redirect Issues
