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

EFFECTIVE Business Practices Common to all Western Regions
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.
