While most states in the U.S. are connected in regional grids, Alaska has two standalone grids (the Railbelt and Southeast Alaska) that serve most of the state's population. It also has more than 150 small, isolated power systems serving remote communities. According to the U.S. Energy Information Administration, fossil fuels generated 68% of the state's electricity in 2022.

Argonne worked with DOE's National Renewable Energy Laboratory (NREL) to evaluate the potential for PSH deployment to enable integration of solar and wind energy in Alaska. Using geographic information systems, the team identified more than 1,800 sites with geography suitable for PSH. This demonstrates the great potential for PSH to help make Alaska's power systems cleaner and more resilient.
