Simply put, we need a reliable and secure energy grid. Two ways to ensure continuous electricity regardless of the weather or an unforeseen event are by using distributed energy resources (DER) and microgrids. DER produce and supply electricity on a small scale and are spread out over a wide area. .
Solar DER can be built at different scales—even one small solar panel can provide energy. In fact, about one-third(link is external)of solar energy in the United States is produced. .
Another way DER and microgrids can contribute to grid stability is by aiding “black start” processes, which turn power on after it has gone down. During a widespread electrical failure, electrical generators can be put offline. To come back online, many. .
Distribution grids are vulnerable to outages that can affect large regions and millions of people and businesses, particularly as a consequence of extreme, destructive weather. [pdf]
