By definition, interoperability is the ability of two or more systems or components to exchange information and to use the information that has been exchanged. Interoperability ultimately means that devices (and systems and people) work well together. In the “What is Interoperability?” video, David Forfia explains the Gridwise Architecture Council’s Interoperability Framework, which outlines three categories of interoperability: organizational, informational and technical. Different levels of interoperability require a trade-off between short-term effort and long-term cost. Higher levels of interoperability require more effort but are lower cost in the long run. Interoperability, by ensuring that components (e.g., distributed energy resources, metering infrastructure, software systems) work well together, increases system-wide benefit and helps achieve policy objectives, including safety, reliability, resilience and affordability.

“NARUC’s interoperability learning modules are an easy way to select bite-sized topics to explore, depending on what topics are most relevant to us at any given moment,” said Wally Nixon, managing attorney at the Arkansas Public Service Commission. “Complicated information is presented in a simplified way by well-versed industry experts.”

"Interoperability is a way to manage risk and costs. Utility regulators can get some great training to understand what they need to know about interoperability through the NARUC interoperability learning modules,” added Commissioner Sarah Freeman of the Indiana Utility Regulatory Commission.
