Success Story—Using Renewable Microgrids to Keep the Lights On
Microgrids are localized electric grids that can disconnect from the main grid to operate autonomously, even with the larger grid is down. While microgrids are still rare—as of 2022, about 10 gigawatts of microgrid capacity was installed in the U.S.—interest in renewable energy microgrids is growing rapidly. Now, thanks to a research project with Siemens
