Con Edison deploys data visualization technology

Waltham, Mass

Con Edison, a subsidiary of Consolidated Edison Inc., has deployed a Web-based data management system using OpenViz data visualization technology from Advanced Visual Systems Inc. (AVS). The new system integrates data from five legacy Con Edison applications into an interactive visual display of real-time power usage of Manhattan and Westchester County and has reduced costs and enhanced reliability for power distribution systems at one of the nation’s largest investor-owned energy companies.

“Because real-time information is now integrated into one visual image on a single monitor, we are able-for the first time-to watch the use of power as it evolves,” said Arthur Kressner, Con Edison’s director of research and development. “We can discover and understand many facets of our operation that were invisible to us in the past,” continued Kressner. “This new capability is changing the way that Con Edison is managing power usage and planning for the future.”

Kressner added, “Our next step is to adapt it so that a number of different audiences can use the application.” Plans include building more links to different data sets so engineers can create contingency models and instantly see the results of their changes. Other plans include a version for Con Edison senior management to use in strategic planning and a version for public and government use.

OpenViz enables data from non-Web-enabled business and financial applications to be integrated and viewed using 2-D and 3-D graphics within a standard Web browser or custom application. For more information, visit
