The nation’s power grid needs the flexibility to accommodate internally or externally driven changes, either expected or unexpected. One example is the integration of distributed energy resources such as solar or wind power. Our energy system is also being revolutionized by the deployment of intelligent devices and systems that offer more flexibility to coordinate operation of grid infrastructure with end-use systems.

The key to delivering greater flexibility and reliability in the face of these changes is interoperability—the ability of different devices and systems to communicate and operate seamlessly. For efficient grid operation, the broader electricity industry must have access to general interoperability requirements, methodologies, and tools that simplify the integration and secure interaction among the many devices and systems that make up the grid.
