Improving smart grid ROI with distributed energy resources. There are various definitions of distributed energy resources. Essentially, they include technologies on the customer side of the meter: Distributed generation, distributed energy storage, solar PV, electric vehicle charging infrastructure, and a focus on microgrid technology to enable renewables to be connected to the grid. Learn what technologies can help overcome the challenges without implementing distributed energy resources.
