Home Planning


Wholesale market participants and, ultimately, energy consumers, benefit from MISO’s coordination of short and long-term planning. Using advanced modeling and thorough research, we help ensure reliable and efficient electricity transmission in our footprint and beyond. 

Generator Interconnection

MISO provides safe, reliable, equal and non-discriminatory access to the electric transmission system for generator interconnection projects. We are committed to helping current and future interconnection customers navigate the interconnection study process. 

Interregional Coordination

MISO works with PJM, SERTP and SPP, its neighboring transmission planning regions, to develop a mutually agreeable method for allocating the costs of transmission facilities that benefit more than one region.

Competitive Transmission Administration

MISO facilitates competition in the electric transmission industry. We utilize a competitive procurement process (developer selection) to select qualified entities to construct, own, operate, maintain, repair, and restore eligible new transmission facilities located within all or parts of the 15 U.S. states in the MISO footprint.

Planning Models

Transmission system models provide the foundation for our planning process. We build reliability (Powerflow and Dynamics) and economic models to support the core planning functions necessary to ensure compliance with our Tariff and North American Electric Reliability Corporation (NERC) standards.

Transmission Planning Studies and Reports

Effective planning for transmission and generation needs must balance system reliability, market efficiency, and state and federal energy policies. We work collaboratively with our stakeholders to develop regional planning studies and regulatory analyses to ensure the continued delivery of reliable, least-cost energy.

Resource Adequacy

In the MISO region, customer-facing utilities are responsible for making sure they can meet customer needs

Long-Term Transmission Service

Transmission customers through out our footprint rely on MISO for transparent and neutral transmission service planning. This results in fair and open access to the region’s transmission system.
