The growth in distributed energy resources presents huge opportunities both in front-of-meter and behind-the-meter but the process of interconnection to the grid could still be a lot smoother, Jason Allnutt, Conformity Assessment Program Specialist for the IEEE Standards Association says. Adoption of distributed energy resources (DERs) is surging around the world. DERs are bringing unique benefits to the global energy landscape that central-station power plants and long-distance transmission and distribution alone could not. DERs allow for power to be generated when and where it is most needed, and decentralising power production can contribute to a dramatically more secure and resilient facility for electricity delivery. DERs interconnected with the grid position a utility to better manage peak demand, avoid transmission overloads and keep electricity flowing to its customers. But interconnection of battery, combined heat and power (CHP), solar, wind, and other DERs is not without its challenges. For example, utilities, DER developers, and DER owners are not always on the same page in terms of precisely how to undertake an installation and who is responsible for which part in the interconnection process.
