Southeastern Utility Adopts GridSense TransformerIQ for a Major Distribution Optimization Project - One of the Largest Deployments in the U.S. To-Date

SACRAMENTO, Calif., June 2, 2011 /PRNewswire/ -- GridSense, a subsidiary of Acorn Energy (Nasdaq:ACFN), and a leader in advanced monitoring systems that support electric utilities worldwide, today announced that a leading Southeastern electric utility, known to be on the forefront of adopting new technology, has selected the company's TransformerIQ to monitor over 2000 transformers in one metropolitan county in its service territory.  This project is expected to be a showcase for Smart Grid distribution optimization demonstrating the scalability and impact of affordable monitoring solutions on electric reliability.  The American Recovery and Reinvestment Act provided half the funding for the project.

There are over 20 million transformers in the United States.  According to Hartford Steam Boiler Inspection and Insurance Company, which insures most transformers in the U.S., the average age of transformers in the U.S. is 37 years old.  Transformers are designed for a maximum 40 year life.  It would cost utilities tens of billions of dollars to replace old and aging transformers, with resulting rate increases to consumers.  

The TransformerIQ is designed to cost less than 2% of the transformers replacement cost, and can help extend their useful lives.  This monitoring platform is easy to install and can monitor up to 28 different parameters including operating temperatures, predicted asset life, system capacity, vault load switching, faults and interruptions and operating current voltage and power factor.  In addition to the compelling savings involved, the use of the TransformerIQ will help utilities avoid prolonged service interruptions.

Lindon Shiao, CEO of GridSense stated, "GridSense is very excited to be selected to play a key role in this important project.  Its successful completion will serve as a model. Other utilities and Public Service Commissions will see how high value, cost-effective investments at a fraction of the replacement cost of grid assets can improve network intelligence and reliability, extend asset lives and prevent unplanned outages."

Kevin Andersen, inventor of the TransformerIQ said, "I have spent my entire career in transformer monitoring and I knew that if we could provide real-time monitoring of all the key parameters of transformer failure, at the right price point, utilities would adopt the product en masse.  All transformers from large generation step-up down to the distribution pole top can now be monitored affordably with the TransformerIQ."

John Moore, CEO of Acorn Energy said, "Electricity is more than just another commodity.  It is our economy's life-blood and the key to our quality of life.  As the world moves into the digital age, power quality will need to grow accordingly.  We believe that the industry will soon appreciate that distribution optimization will have a bigger impact than demand response.  By transforming our existing infrastructure into a smarter grid, we will help ensure our ability to meet growing electricity demands."
