We began the 2017 MISO Transmission Expansion Planning report - MTEP17 - in 2016 when stakeholders first submitted proposed transmission projects. MISO engineers and stakeholders continue to evaluate each proposed project to determine whether the project is appropriate for inclusion in MTEP17.
MISO’s Board of Directors considers approval of the MTEP report during its final meeting in December of each year. Each MTEP report also includes the status of previously-approved MTEP projects and chapters about recent and current transmission planning studies and findings.

Expedited Project Review
Some circumstances require project approval prior to the next annual MTEP cycle. Transmission Owners may justify an Expedited Project Review study if it will help drive a timely response to significant load additions or other new system needs that require budgeting, regulatory milestones, construction and other project development support prior to approval of the next MTEP.

We work with our stakeholders to develop MTEP Futures to “book-end” uncertainty by defining a wide range of potential outcomes. While MTEP Futures consider scenarios that could come to fruition within the next five years, we use Futures to help us plan for uncertainty that could affect our industry 15 years from now. For the MTEP17 cycle, we worked with stakeholders to create three Future scenarios: Existing Fleet, Policy Regulation, and Accelerated Alternative Technologies.
MTEP17 Futures Summary
Generation Retirement Sensitivity Analysis
The Retirement Sensitivity Analysis will allow MISO and stakeholders to identify indicative transmission system needs based on forecasted generator retirements (age based retirements) within MISO and will allow use of that information in long term planning.

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