DISCLAIMER: WAPA's Open Access Transmission Tariff (OATT) is filed
with the Federal Energy Regulatory Commission (FERC). WAPA's
filings and associated FERC orders establish the rates, terms
and conditions of service. These documents are prepared
for the convenience of WAPA's customers and any conflicts
between these documents and the version filed shall be resolved
in favor of the version filed. FERC
provides a tariff viewer to help the public review tariff
provisions electronically at the following URL: http://etariff.ferc.gov/TariffList.aspx.
Note 1. The Upper Great Plains (UGP)
Region of WAPA joined the Southwest Power Pool, Inc. (SPP)
as a transmission owner and transferred functional control
of all of its eligible transmission facilities to SPP on
October 1, 2015. Transmission service over those UGP
Regional transmission facilities is available solely under
the SPP Open Access Transmission Tariff (SPP
Tariff). Ancillary services offered by the UGP
Region as a Balancing Authority operator are also solely
available under the SPP Tariff. Therefore, certain
WAPA OATT provisions may not be currently applicable in
the UGP Region.
