MISO is committed to providing value and reliability for our stakeholders and our region, which spans parts of 15 states and the Canadian province of Manitoba. Our primary mission is ensuring the reliable and cost-effective operation of the electric grid. We also conduct regional transmission planning and administer one of the largest wholesale electric markets in the world. Executing those functions on a regional basis allows for the creation of an estimated $3.5 billion in annual benefits.
The energy industry has become very dynamic due to a number of factors, including energy policy, regulation, fuel economics and customer preferences. The changing landscape requires that the region must evolve to ensure continued reliability and value creation going forward. A diversity of voices is critical to identify and develop the needed changes and enhancements for the continued success of the region. The MISO community enjoys such a diversity of viewpoints and we always welcome additional voices.
There are a number of ways to become involved in the MISO Region, from becoming a MISO Member (for eligible entities) to simply attending and participating in public meetings where much of the work occurs to continually evolve rules, tools, processes, etc., to ensure preparedness for the future. Public meetings are organized around certain functions or aspects of MISO, through a structure of subcommittees, or entities that make up our stakeholder process. In certain entities input and voting takes place by Stakeholder Sectors, which are related to different segments of the industry. There are currently 11 Sectors in the MISO stakeholder process to allow similarly focused companies to align their participation.

Officially called “The Agreement of Transmission Facilities Owners to Organize the Midwest Independent Transmission System Operator, Inc., A Delaware Non-Stock Corporation ("MISO Agreement").”
This multi-party contract between the MISO, International Transmission Company (“ITC”) and each of the MISO Transmission Owners amends the Appendix I Agreement between ITC and the MISO.
By signing Appendix G of the MISO Agreement, Transmission Owning Members will authorize MISO to act as the agent in the performance of Tariff administrative duties related to "Non-transferred Transmission Facilities."
This agreement, between the MISO and the MISO Local Balancing Authorities, resulted from negotiations regarding the establishment and implementation of the MISO Ancillary Services Markets.
