The Maine Public Utility Commission (PUC) adopted interconnection procedures in January 2010; the rules were last updated in 2020. These rules apply to all transmission and distribution utilities operating in the state and apply to all distribution generation (not just renewables).

These are:

• Level 1: Small certified generating, inverter-based facilities 25 kilowatts (kW) or less;
• Level 2: Certified facilities 2 megawatts (MW) or less;
• Level 3: Non-exporting, certified facilities 10 MW or less;

Carteret County passed an ordinance to specify the permitting process and establish siting requirements for wind energy systems. There are different rules and a different permitting process depending on the size and location of a system. Small systems up to 25 kilowatts (kW) are considered to be an accessory use and do not require the approval of a Wind Energy Permit Application. Small systems attached to a house can have a maximum height of 60 feet and are not subject to minimum setbacks. Small systems not attached to a house can have a maximum height of 75 feet, but must

The Public Service Board (PSB), now the Public Utilities Commission of Vermont, developed rules regarding utility line extension requests. While the majority of the regulations focus on the procedure followed (and associated fees) for the actual line extensions, the PSB also included a provision that requires electric utilities to provide written information to customers upon request about off-grid electricity generators as an alternative to line extensions. The PSB recognized that in many cases, off-grid electricity generators are less expensive than extending the electricity distribution lines, and therefore customers should be made aware of this option.
