Americans for Prosperity this year has led a nationwide "Hot Air Tour," featuring a 70-foot-tall hot-air balloon that has helped expose the hot air of global warming alarmists, whose proposed legislation would lead to "higher taxes, lost jobs and less freedom." The group last week also held a news conference in Denver with U.S. Sen. Jim DeMint and the Coalition for a Conservative Majority to call on Congress to let the ban on offshore drilling and oil shale development expire as scheduled on Oct. 1.

On the issue of wasteful spending, the group two years ago also conducted a national 10,000-mile "Ending Earmarks Express" bus tour that exposed questionable federal spending at 50 locations in 38 states. The tour brought Phillips to Alaska's infamous "Bridge to Nowhere," where he recorded a video (http://www.youtube.com/watch?v=f6q__0-krUo) that has been featured on numerous national television broadcasts.

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.
