Planning for the future

MISO Transmission Expansion Plan (MTEP) is MISO’s process for determining the new transmission projects needed to cost effectively deliver low cost electricity, to meet future policies and comply with existing regulatory and reliability standards. CGA’s technical and policy expertise is valuable in providing MISO guidance regarding future modeling scenarios and methodologies.  

MTEP is the process MISO uses to determine what transmission lines are needed to ensure reliability, to support state and federal energy policies, and deliver low-cost energy to customers within MISO’s region.  The planning process is conducted annually by MISO and forecasts system conditions for the next 15 years.  The process involves consideration of factors such as areas of congestion, anticipated electric generating plant closures or retirements, mapping and ranking of the best wind and solar development zones in the region, projecting how much energy will be needed to meet demand, projecting how much wind and solar generating capacity will be built, and considers the impact of state, regional, and federal policies, such as renewable energy standards or the U.S. EPA's Clean Power Plan.

Clean Grid Alliance participates in the MTEP process on behalf of its members, presenting oral and written comments through the stakeholder process, to ensure the modeling reasonably accounts for wind and solar development over the next 15 years.  Our comments provide recommendations on the modeling of future scenarios, evaluating variables and prices used in the modeling, as well as ensuring state and federal policies are factored.
