The Alaska Interconnection refers to the electric power systems within the state of Alaska, which are not physically connected to the three major North American power grids: the Eastern Interconnection, the Western Interconnection, and ERCOT (Texas). Instead, Alaska’s electricity infrastructure consists of several isolated regional grids, including microgrids that operate independently across remote and rural communities.
Because these isolated grids cannot rely on energy imports from neighboring states or regions, Alaska depends heavily on local energy resources, including diesel generators, renewables (wind, hydro, solar), and increasingly, battery energy storage systems (BESS).
In the battery industry, the Alaska Interconnection is a key reference point for:
Energy resilience in remote/off-grid environments
Deployment of batteries to stabilize isolated grids
Enabling higher renewable energy penetration
Reducing dependency on imported fossil fuels
