MISO Transmission Expansion Planning (MTEP) 

The system expansion plans produced through the MISO planning process must ensure the reliable operation of the transmission system, support achievement of state and federal energy policy requirements, and enable a competitive electricity market to benefit all customers. The planning process, in conjunction with an inclusive, transparent stakeholder process, must identify and support development of transmission infrastructure that is sufficiently robust 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 in the assignment of transmission projects.

  • Guiding Principle 1: Make the benefits of an economically efficient electricity market available to customers by identifying transmission projects which provide access to electricity at the lowest total electric system cost.
  • Guiding Principle 2: Develop a transmission plan that meets all applicable NERC and Transmission Owner planning criteria and safeguards local and regional reliability through identification of transmission projects to meet those needs.
  • Guiding Principle 3: Support state and federal energy policy requirements by planning for access to a changing resource mix.
  • Guiding Principle 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.
  • Guiding Principle 5: Analyze system scenarios and make the results available to state and federal energy policy makers and other stakeholders to provide context and to inform choices.
  • Guiding Principle 6: Coordinate planning processes with neighbors and work to eliminate barriers to reliable and efficient operations.

The projects listed in Appendix A of the MTEP Report constitute the essential transmission projects recommended to the MISO Board of Directors bi-annually basis for review and approval. In aggregate, these projects will:

  • Ensure the reliability of the transmission system
  • Provide economic benefits such as increased market efficiency
  • Facilitate public policy objectives such as integrating renewable energy
  • Address other issues or goals identified through the stakeholder process

Planning and Cost Allocation

Our transmission cost allocation approach seeks to match transmission projects with the cost allocation method which best corresponds to the spread of the project’s benefits.

Stakeholder Involvement

Planning study reviews and discussions occur in several stakeholder forums, including the Planning Advisory Committee and Planning Subcommittee.
