    Welcome to BPA Transmission Services

    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.
