Xcel Energy and Teradata Partner to Meet Changing Market Demands

Leading the Utility Industry with Sophisticated Enterprise
Analytics
MIAMISBURG, Ohio--(Business Wire)--
To meet the rapidly changing demands of the utility industry, Xcel
Energy (NYSE: XEL) is collaborating with Teradata Corporation (NYSE:
TDC), the global leader in enterprise data warehousing to further
develop its advanced analytics and user self-service capabilities. The
initial scope of effort will combine the utility's data on meters,
billing, and collections, and enable detailed segmentation and
powerful analytics.

"Xcel Energy is an industry leader when it comes to moving the
energy grid into the modern age, and we need to be prepared to manage
the massive amount of real-time data being generated," said Michael
Carlson, chief information officer, Xcel Energy. "We believe there
will be a tremendous opportunity to leverage that information towards
automating the management of the grid. This collaboration is expected
to provide the scalability and performance we need for making smarter
business decisions."

The new Teradata system, which includes Teradata's market-leading
analytical software running on the recently introduced Teradata 5550
server, an active data warehouse-class platform, will be in production
by late summer. In addition, Xcel Energy will employ a Teradata
Logical Data Model being developed for the utility industry to
represent enterprise data, data relationships, topic areas, and
business rules.

"We are integrating data into a single environment to allow
end-to-end views of our business and help us understand cause-effect
relationships across our value chain," said Brian Jore, director of
business analytics, Xcel Energy. "This centralized environment will
allow our analysts and business users to identify ways to maximize
revenue recovery, reduce costs and improve customer satisfaction."

In the past Xcel Energy required information to be pulled from
different sources and pieced together to give a static picture of the
business. With this new solution, the company will be able to quickly
and easily answer inter and intra department and business unit
questions.

"Utilities around the world are prioritizing analytics and
innovation. Teradata can assist by providing the ability to load all
the new data being generated in near real time, integrating it, and
driving powerful analysis and reporting against the resulting
information for a utility's employees and customers. We are excited to
be assisting Xcel Energy as they continue to lead the industry," said
Teradata Industry Vice President Tony Samuels.
