Pilots and Demos Database

This database compiles and presents a variety of energy storage pilot and demonstrations projects around the world. The entries can be organized and filtered in various ways, including by vendor and product name, technology type, size and capacity, installation location and date, project description and partners. The database is a work in progress and always expanding, so please feel free to provide information about other projects to include and feedback for improvements to the team.
