GridSense Launches Newest Transmission and Distribution Line Monitoring System for Electric Power Industry

SACRAMENTO, Calif., Feb 1, 2011 /PRNewswire/ -- GridSense, a subsidiary of Acorn Energy, Inc. (Nasdaq: ACFN), and a leader in advanced monitoring systems that support distribution automation and grid operations of electric utilities worldwide, today announced the commercial launch of its latest transmission and distribution line monitoring system, the LineIQ™.

"The LineIQ™ assists utilities in improving their reliability even in the face of aging infrastructures," said Lindon Shiao, CEO of GridSense. "Today, when a fault is detected on the grid, a utility will typically be forced to shut down large surrounding areas to prevent its spreading. LineIQ™ is a sophisticated tool with more advanced and efficient real-time reporting capabilities that enable utilities to pinpoint line faults, and to restore service to all but the affected area."

With the introduction of new functionality like accurate voltage measurement, and additional monitoring parameter capabilities, the LineIQ™ addresses essential smart grid and distribution automation applications such as outage management, line balancing and capacity optimization.

John Moore, CEO of Acorn Energy noted, "Newton Evans, a leading research company with a focus on the worldwide electric power industry, recently reported that current North American spending for substation automation and integration programs is over $500 million, with an overall market potential of nearly $10 billion. The LineIQ™ will be an important solution for this fast growing market, and along with the GridSense TransformerIQ™ system, provide key building blocks to help the industry realize its vision of a 'self healing' grid."

GridSense will exhibit the LineIQ™ system at the upcoming Distributech conference (Booth 2627) to be held in San Diego from February 1-3, 2011. GridSense will also be displaying its full range of product offerings which span the transmission and distribution grid, including the TransformerIQ™ product family. As the company's comprehensive and intelligent transformer monitoring platform, the TransformerIQ™ has a number of newly added features. In addition to being able to capture every failure mode in a package that is retrofitable to the largest and most complex transformers, the TransformerIQ™ system can also be configured affordably for the smallest distribution applications.
