Microgrids provide a tiny fraction of U.S. electricity. At the start of 2023, the United States had 692 microgrids installed, with a total capacity of nearly 4.4 gigawatts. More than 212 of those with a capacity of more than 419 MW has come online in the last four years. Most microgrid projects are in Alaska, California, Georgia, Maryland, New ...
