Phase II - Integration of Resource/Distribution/Transmission Planning

MI Power Grid Optimizing Grid Investments & Performance Stamp

Notice: MI Power Grid meetings and all other MPSC workgroup meetings will be conducted via teleconference only until further notice. Please find remote access information for upcoming meetings on our calendar of events.


Utility companies and stakeholders engage in separate processes to determine what upgrades to make to the electric resource mix, transmission system, and distribution system. Decisions made in each of these processes impact customer costs. Doing a better job of integrating these processes, with the goal of evaluating alternatives that provide the best value, will result in a more efficient system and lower costs for customers.
