Benefits of Distributed Energy Resources: Shifting the Energy

When an energy consumer owns and operates distributed energy resources, they can fully participate in the energy economy. This means that the consumer can sell their excess energy back to the grid. As a result, the consumer becomes a prosumer, meaning that they use and produce energy at the same time.
