Midwest ISO Planning and Study Efforts

Midwest ISO has taken a proactive role in determining the potential impacts, risks, and methods to integrate renewable energy into the electric transmission system and energy market. Numerous planning studies and efforts are underway to determine and mitigate the long term impacts of renewable energy on the transmission system.
The Midwest ISO is the NERC Planning Authority for its member footprint and performs regional planning in accordance with FERC Planning Principles delineated in Order 890. The fundamental goal of the planning process at the Midwest ISO is to develop a comprehensive expansion plan that meets reliability needs, policy needs, and economic needs. This is achieved through recognizing the following principles defined by the Midwest ISO Board of Directors:
- Make the benefits of a competitive energy market available to customers by providing access to the lowest possible electric energy costs
- Provide a transmission infrastructure that safeguards local and regional reliability and supports interconnection-wide reliability
- Support state and federal renewable energy objectives by planning for access to all such resources (e.g. wind, biomass, demand side management)
- Provide an appropriate cost allocation mechanism
- Develop a transmission system scenario model and make it available to state and federal energy policy makers to provide context and inform the choices they face
Below you will find an overview of some of our key transmission planning initiatives and links that will provide detailed information on each study.

Regional Generation Outlet Study
RGOS I has been substantially influenced by the guidance of the Upper Midwest Transmission Development Initiative (UMTDI). More information on the UMTDI may be found on their website.
