    Posted 6/10/2015:   SE Idaho Load Update
    BPA has an update on the option that was identified as its top priority for service to customer loads in Southeast Idaho. Please see the update for additional information.

    Posted 04/06/2015:   Suspension of Partial Offers of Less Than 12 Months to Long-Term Service Requests
    Effective immediately, BPAT is suspending making partial service offers of less than 12 months in duration to long-term firm requests as set forth in its current Partial Long-Term Firm Service Business Practice. BPAT is taking this action to reconsider its policy regarding these offers. BPAT expects the suspension to last approximately two months.

    BPAT is rescinding current offers of partial service less than 1 year in duration unless customer(s) who received those offers want to accept them and take the service. Offers that have already been confirmed by the customer on BPA's OASIS will not be rescinded.

    The suspension does NOT apply to partial offers that are 1 year or longer in duration. Customers receiving these offers must confirm the counteroffer on OASIS or BPAT will remove them from the queue.

    In the coming weeks, BPAT will solicit customer comment on its policy regarding partial offers that are less than 12 months in duration. Questions should be directed to the appropriate Transmission Account Executive or the BPAT Reservation Desk.

    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 4/2/14:   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 2/13/14:   Update: Invalid Reservation Points for Transmission Service Requests on BPA Network
    BPAT deactivated the USCNDNBDRE230, NELWAY230, and WANETA230 points in OASIS on 02/12/2014. BPAT may reactivate these points, as needed, to modify how it models and reserves capacity for the Canadian Entitlement Return obligation required under the Columbia River Treaty. 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.

    Originally Posted 5/16/13:   Reminder: Invalid Reservation Points for Transmission Service Requests on BPA Network
    BPA Transmission Services (BPAT) would like to remind its customers that on August 10, 2010, BPAT posted a notice on its OASIS that the following points are not valid reservation points for transmission service on its OASIS:

    • NELWAY230
    • WANETA230

    BPAT reminds customers that any new requests for service using these points will be deemed INVALID by BPAT.
