Win in the flat world
Case Study
Integration of the CIS system of a large
western utility with multiple AMI
systems and an MDM system
Oct 2008
Abstract
Infosys is working with a leading North American Utility to integrate its CIS
system with multiple AMI and MDM systems. As a trusted integration
partner, Infosys helped the utility define the integration architecture and the
business processes required to achieve business benefits. The solution
leverages Infosys' AMI-MDM integration experience and service offerings
for implementing large scale integration programs.
Client Overview
The client is a leading investor-owned electric utility in
western US that distributes power to more than 1 million
customers in 11 counties. It operates over 5,500 miles of
transmission lines and more than 28,500 miles of

vision of the organization
• Automate the business operations related to meter
reading and field services
• Manage interval meter data effectively and utilize the
data for decision making
• Establish processes and systems to support demandside management
• Implement robust and intelligent processes for early
outage detection making outage management more
efficient
• Reduce power theft
• Create customer-centric processes for higher customer
satisfaction
To cater to these needs, the client planned to deploy smart
meters in the field and an MDM system to manage the
increased volume of meter data. To meet these needs,
the customer information system had to be integrated with
these systems.

Integration Solution
The figure below shows the integration blue print designed
for the client. There are various heterogeneous
applications in CIS integrated with two AMI systems and
an MDM system over the Enterprise Service Bus. The
above solution is designed based on SOA (Service
Oriented Architecture).
The AMI and MDM systems have web service interfaces.
There are interfaces built on ESB (Enterprise Service Bus)
to transform the web service interfaces to standard
interfaces built on CIM (Common Interface Model). There
is a Business Orchestration component to orchestrate the
requests from CIS applications based on the business
rules.
The orchestrated functions are deployed as services on
these services in the future. It also provides flexibility to
the ESB for heterogeneous applications. This approach
change orchestration rules as needed.
