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:
| Line Voltage | Fast Track Eligible Regardless of Location | Fast Track Eligibility on a Mainline and less than 2.5 Electrical Circuit Miles from Substation |
| Less than 5 kV | Less than or equal to 500 kW | Less than or equal to 500 kW |
| Greater than or equal to 5 kV and less than 15 kV | Less than or equal to 1 MW | Less than or equal to 2 MW |
| Greater than or equal to 15 kV and less than 30 kV | Less than or equal to 3 MW | Less than or equal to 4 MW |
| Greater than or equal to 30 kV, up to 69 kV | Less than or equal to 4 MW | Less than or equal to 5 MW |
