Energy Storage Technologies Primer | POWER Magazine

Though often lumped together under the term “energy storage,” the field is in fact a wide range of technologies ranging from well established to speculative, each with different functions, advantages, and drawbacks. The discussion below focuses on existing grid-scale (greater than 1 MW rated power) projects and is generally ordered by level of deployment.

Distributed Generation-Integrated Value

Distributed generation (DG) is the name given for generating power at the point of consumption. With DG, electricity is produced at many small, dispersed generating sites, rather than at large, centralized, traditional power plants. Some of the most recognizable distributed resources include solar, wind, and small gas turbines.
