GridSense(TM), An Acorn Energy Company, Provides Affordable Monitoring of Electric Vehicle's Impact on Power Grid

SACRAMENTO, Calif., Jan. 9, 2013 /PRNewswire via COMTEX/ -- GridSense(TM), an Acorn Energy (NASDAQ: ACFN) company that develops and markets advanced monitoring solutions for the electric power industry, has been working with utilities to monitor the effects of electrical vehicle (EV) loads on the residential grid. Using its TransformerIQ(TM) monitoring solution and Grid Insite(TM) proprietary software, GridSense(TM) is able to monitor the load on residential transformers without costly infrastructure prerequisites.

Although initial data indicates slower than anticipated adoption rates nationally for EVs, they are gaining popularity in West Coast US metropolitan areas whose populations are early adopters. Clustered in urban environments, EVs can place a major strain on our aging electrical grid.

According to a study led by Dr. Ghinam Putrus at Northumbria University, "EVs may be considered as active loads, increasing the demand on the network during charging, and as generators when operating in regeneration mode. Therefore, the impact of EVs when operating in both modes, charging and regeneration, need to be analyzed." Unfortunately, many utilities don't have intelligence on normal residential transformer load. Therefore, they can't predict how these transformers will react to the addition of disruptive EV loads. With TransformerIQ(TM), utilities can begin with a small pilot to develop a baseline for residential transformer load. The Grid InSite(TM) hosted platform lets them access the data via cellular connection quickly, with minimal IT involvement, and no long-term commitment.

"In TransformerIQ(TM) and Grid InSite(TM) we have developed a versatile tool that is solution for a variety of pain points on the electric grid. Across the world we are seeing utilities deploy this technology for data collection in urban, suburban and rural environments to aid in the resolution of their varied issues. Our customers are finding the combination of a cost-effective device that installs simply and non-invasively with immediate and almost effortless data access through Grid InSite(TM) to be extremely attractive," says GridSense Sales Manager, Brandy Henson. "It removes a lot of the pain of testing and piloting for new technologies like EVs and PhotoVoltaics. Utilities may have thousands of poletops, but monitoring even one can garner instructive intelligence. This system makes such monitoring very practical." About GridSense Inc.
