MISO Transmission Expansion Plan

The MISO Transmission Expansion Plan (MTEP) is developed annually through an inclusive and transparent stakeholder process. MISO evaluates various types of projects through the MTEP process that, when taken together, build an electric infrastructure to meet local and regional reliability standards, enable competition among wholesale capacity and energy suppliers in the MISO markets, and allow for competition among transmission developers. 

NEW ... Planning Portal!

The MISO Project Portal is moving to a new platform which you may know as the MISO Help Center. This new portal will provide a robust user-friendly experience that will support the submission and management of MTEP projects throughout their lifecycle while enabling the integration capabilities for future MISO technologies.

Guiding Principles

  1. Develop transmission plans that will ensure a reliable and resilient transmission system that can respond to the operational needs of the MISO region.
  2. Make the benefits of an economically efficient electricity market available to customers by identifying solutions to transmission issues that are informed by near-term and long-range needs and provide reliable access to electricity at the lowest total electric system cost.
  3. Support federal, state, and local energy policy and member goals by planning for access to a changing resource mix.
  4. Provide an appropriate cost allocation mechanism that ensures that costs of transmission projects are allocated in a manner roughly commensurate with the projected benefits of those projects.
  5. Analyze system scenarios and make the results available to federal, state, and local energy policy makers and other stakeholders to provide context and to inform choices.
  6. Coordinate planning processes with neighbors and work to eliminate barriers to reliable and efficient operations.
