Alaska Interconnection

American AC power transmission grid

The Alaska Interconnection (ASCC) is an AC power transmission grid in North America that serves Central and Southeast Alaska. While the Alaska Interconnection is often referred to as one interconnected grid, its two parts are not connected to each other through interconnectors, nor are the two grids connected to any other interconnection, making the grids in Alaska isolated circuits.2 Wikipedia text CC BY-SA 4.0
