OASIS

Open access same-time information system, ​(OASIS), is an Internet-based tool for sharing information on transmission prices and product availability. FERC Order No. 889 restricts communication between power marketing and transmission operation employees within any one organization. Utilities can obtain information about their own transmission system for their own wholesale power transactions only through OASIS. Customers can view Available Transmission Capability; submit transmission service requests, etc. on the applicable region’s OASIS site(s) below:

DESERT SOUTHWEST REGION TRANSMISSION (TSP = WALC)

Upper Great Plains transmission (TSP = WAPA)

The Upper Great Plains region (UGP), based in Billings, Montana, manages transmission facilities in Montana, North Dakota, South Dakota, Nebraska, Minnesota and Iowa. These transmission facilities were constructed to market and deliver power from the Pick-Sloan Missouri Basin Program—Eastern Division. UGP joined the Southwest Power Pool, Inc. (SPP) as a transmission owner and transferred functional control of all of its eligible transmission facilities (in both the Eastern and Western Interconnections) to SPP on Oct. 1, 2015. Transmission service over those UGP Regional transmission facilities is now available solely under the SPP Open Access Transmission Tariff (SPP Tariff) via the SPP OASIS. UGP manages a Balancing Authority Area in the Western Electricity Coordinating Council region called Western Area Power Administration—Upper Great Plains West, or WAUW from its Control Center in Watertown, SD. UGP merged its Balancing Authority Area in the Midwest Reliability Organization region called Western Area Power Administration—Upper Great Plains East, or WAUE into SPP's Balancing Authority Area when it joined SPP on Oct. 1, 2015. Ancillary services offered by UGP as the WAUW Balancing Authority operator are also solely available under the SPP Tariff.
