The Consumer Electronics Association (CEA) is an American National Standards Institute (ANSI) standards-development organization. Within the CEA R07 Home Networks Committee, Subcommittee 8 (R7.8) is titled “Modular Communication Interface for Energy Management.” This subcommittee was created in 2012, following a period in which the National Institute of Standards and Technology (NIST) Home-to-Grid Domain Expert Working Group (H2G DEWG) had developed a concept design of a modular communication interface. The NIST design incorporated elements from prior EPRI research, the USNAP Alliance, and other modular interfaces from around the world.

In February 2013, the CEA released the ANSI/CEA-2045 standard. This standard defines a “port” or “plug” interface that could be incorporated into off-the-shelf appliances during manufacture in order to make appliances ready to receive and respond to utility demand-response signals. ANSI/CEA-2045 standard includes the mechanical, electrical, and logical features that are required to enable communication modules of any type to be plugged into the appliance.

This report provides a general overview of this standard. It explains the background of its development, the technical characteristics of the interface, and the capabilities that it supports. The present status is described, including continued developments of the standard, vendor engagement, field testing, and applications beyond load management.
