Interconnection Standards and Worker Safety

MI Power Grid Integrating Emerging Technologies 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.

Interconnection standards are rules that spell out how projects owned by customers or developers connect to the utility system. These rules provide a standardized process and schedule so that interconnections can be accommodated in an orderly and timely manner. The rules also ensure that interconnections are done safely, in order to protect workers, utility and third-party owned equipment, and the public.

Written comments may be submitted until 5:00 p.m. on November 1, 2021. More details are provided in the order
