Transmission Business Relations (TBR) provides transmission contract negotiation and customer relations for the four Xcel Energy operating companies, Northern States Power Minnesota (NSPM), Northern States Power Wisconsin (NSPW), Public Service Company of Colorado (PSCo) and Southwestern Public Service Company (SPS). TBR is responsible for all transmission related interconnections (load, transmission, and generation), maintenance and or operating agreements, asset sales or exchanges and the management of all small and large Xcel Energy transmission customer agreements.
NSPM and NSPW are members of the Midcontinent Independent System Operator, Inc. (MISO). New generation and transmission interconnections are subject to the MISO Tariff on file with the Federal Energy Regulatory Commission (FERC). New load and transmission interconnections are subject to the Xcel Energy Operating Companies Tariff also on file with the FERC.
PSCo new interconnections are subject to the Xcel Energy Open Access Transmission Tariff.
SPS is a member of the Southwest Power Pool (SPP). New generation and transmission interconnections are subject to the SPP Tariff on file with the Federal Energy Regulatory Commission (FERC). New load and transmission interconnections are subject to the Xcel Energy Operating Companies Tariff also on file with the FERC.
The applicable Tariff (see MISO, Xcel Energy and SPP) should be reviewed in addition to the applicable transmission interconnection guidelines.
Xcel Energy's transmission interconnection guidelines are available for download at the bottom of this page. These guidelines represent the most current information consistent with rules and regulations as of the date of the document.
