Distributed Energy Resources

Distributed energy resources (DER) are smaller power sources that can be aggregated to provide power necessary to meet regular demand. As the electricity grid continues to modernize, DER such as storage and advanced renewable technologies can help facilitate the transition to a smarter grid.

Deploying DER in a widespread, efficient and cost-effective manner requires complex integration with the existing electricity grid. Research can identify and resolve the challenges of integration, facilitating a smoother transition for the electricity industry and their customers into the next age of electricity infrastructure.

Energy storage technologies can be utilized as an effective resource to add stability, control and reliability to the electric grid. Historically, use of storage technologies has been limited by a lack of cost-effective options when compared to cheaper sources of power, like fossil fuels. However, the recent availability of lower-cost, longer-lived storage technologies as well as evolving economies for traditional transportation and grid technologies has once again made storage an attractive option.

Since wind and solar energy resources are intermittent by nature, energy storage technologies can provide necessary power during low generation periods to help keep the system stable. EPRI’s research analyzes how storage technologies’ costs can be decreased through manufacturing-scale experiences and lead to increased storage deployment and newer technologies that maximize opportunities for the industry and society.


Integrating distributed renewable generation resources such as solar and wind into the electric grid poses a number of challenges for the electricity industry. Utilities face various generator sizes, connection points and electronic interfaces that add complexity to keeping the system stable. This includes cases of relatively high penetration of power from these resources on existing distribution systems.

EPRI research addresses these challenges by assessing feeder impacts, inverter interface devices, analytics, studies, monitoring, special applications, and developing strategies related to future business impacts. A primary objective is to expand utility hands-on knowledge to monetize the cost and value of distributed renewable generation without reducing distribution safety, reliability, or asset utilization effectiveness.


Demand response is a term that describes how distributed electricity can be managed during critical times through the use of signals. EPRI is assessing, testing, and demonstrating the application of technologies in integrated energy management control systems, linking smart thermostats, lighting controls, and other load-control technology with smart end-use devices to enable more sophisticated and effective demand response approaches in homes and buildings. Our research also offers our members an opportunity to work collaboratively with other utilities, government agencies, and manufacturers to define the requirements of end-use devices that are designed to be “out of the box-ready,” creating the potential for dramatic operational and cost benefits.
