The utility here in Montana requires any small-generator facility to have an interconnection agreement with them. A standard net-metered agreement is called a Level 1 Agreement and a non-export system falls into their Level 3 Agreement. The relevant text from that agreement is as follows:
*The... requirements are designed to ensure that the Small Generator Facility... are designed to prevent back-feeding of power from the generating facility to the utility grid during power outages, and to match... power characteristics with respect to voltage and frequency.* Cheers, Sam [image: OnSite Energy] <https://www.google.com/url?q=https://onsiteenergyinc.com/&source=gmail-html&ust=1677085494759000&usg=AOvVaw2NN36GoM1sjnS4RdC8Svt-> SAM HARALDSON Operations Specialist (406) 551-6135 1515 N.
