These systems store excess energy produced by solar panels and wind turbines, ensuring a reliable supply even when the sun isn't shining or the wind isn't blowing. This capability not only enhances grid stability but also supports the integration of renewable energy into the broader. Energy storage, such as batteries, can also be distributed, helping to ensure power when solar or other DER don't generate power. Below are three sources to explore the State's installed storage. Unlike traditional centralized power plants, which supply electricity from a single large source, DERs are small-scale units that generate or store energy close to the point of. Distributed Energy Resources (DER) encompass small-scale units, including solar panels, battery storage, and electric vehicles.
