A new Shared Architecture for integrating electric utility control centers

Shared Architecture provides the infrastructure for an electric utility to integrate control center systems with other utility operations systems using the principles of a Service Oriented Architecture. In the electric utility environment, software systems may have been purchased from different vendors or built in-house, resulting in a diverse computing environment with point to point interfaces between these systems. The Shared Architecture includes an Enterprise Service Bus (ESB), and an expanded set of Shared Architecture services which may be used to upgrade the utility computing environment. Existing legacy systems may be converted to Business Service Components (BSCs) which provide data and services to other systems using the ESB for communications, and the Shared Architecture for base services.
