The Minnesota Public Utilities Commission (MPUC) adopted updated interconnection standards in June 2019. The standards are modeled after the Federal Energy Regulatory Commission’s Small Generator Interconnection Process and apply to systems up to 10 MW in capacity.
The MPUC standards, like the FERC standards, use a three-tiered approach to simplify the interconnection process:
- Inverter Process: Systems up to 20 kilowatts (kW)
- Fast Track Process: Systems larger than 20 kW that meet the eligibility criteria in the table below
- Study Process: Systems that fail to qualify for the Fast Track Process
