Organizational Overview

Southwest Power Pool, Inc., a nonprofit organization founded in 1941, is one of nine Federal Energy Regulatory Commission (FERC)-approved Regional Transmission Organizations (RTO). As an RTO, SPP ensures reliable supplies of power, adequate transmission infrastructure and competitive wholesale prices of electricity. 

Regulatory Oversight

The Federal Energy Regulatory Commission (FERC) is an independent federal agency that regulates the transmission and wholesale sales of electricity in interstate commerce, governs the rates, terms and conditions of SPP through its Open Access Transmission Tariff (OATT or Tariff), in addition to the Membership Agreement and Bylaws. Changes made to any of those documents must be approved/accepted by FERC before SPP can operate under the requested changes.


FERC requires that all jurisdictional entities file their Tariffs and related documents in an electronic system. You can read, download and search SPP's OATT, Governing Documents Tariff (Membership Agreements and Bylaws), Service Agreements Tariff and Rate Schedules and Seams Agreements Tariff on SPP's Interactive Tariff page

When visiting the eTariff page, by expanding sections (tariff, filing, docket, order) under the document locator, select a title (Open Access Transmission Tariff, for example), then click document generation (located above the related items tab of the viewer). This will allow you to select different sections of a document to then generate in a downloadable Word or PDF file.

The North American Electric Reliability Corporation is the electric reliability organization for North America, subject to oversight by the Federal Energy Regulatory Commission and governmental authorities in Canada. NERC's jurisdiction includes users, owners and operators of the bulk power system, which serves more than 334 million people.

The SPP Regional State Committee is comprised of one designated commissioner from each state regulatory commission having jurisdiction over an SPP Member and was established to provide both direction and input on all matters pertinent to the participation of the Members in SPP.
