IEEE SCC 36 (Utility Communications Architecture, UCA) has unanimously decided to publish the UCA Version 2 specification as IEEE Technical Report (IEEE TR 1550) in July 1999. (05/99)

The Utility Communications Architecture (UCA) is a standards-based approach to utility communications which provides for wide scale integration at reduced costs, and which solves many of the most pressing communications problems for today's utilities. The UCA is designed to apply across all of the functional areas within the electric, gas, and water utilities. These functional areas include customer interface, distribution, transmission power plant, control center, and corporate information systems.

It is important to note that UCA is an architecture, rather than a simple, protocol. The UCA Version 2.0 incorporates a family of basic communications protocols to meet the requirements of a wide range of utility environments. The selection and organization of these protocols has been designed to provide great flexibility in choosing the appropriate technology to meet a utility's price/performance criteria, while maintaining consistency at the device and data level to reduce integration and vendor product costs. In addition, the UCA includes detailed object models, which defines the format, representation, and the meaning of utility data. This modeling effort goes far beyond the scope of any other utility communications approach, and provides for an unprecedented level of multi-vendor interoperability.

The combination of broad scope and detailed object modeling makes the UCA specifications more complex than a typical protocol document.
