Dominion Invests $3 Million In Smart Grid Technology Firm

Jan 20, 2010 (FinancialWire via COMTEX) -- (Comment on this article at January 20, 2010 (FinancialWire) -- Energy company Dominion (NYSE: D) said that it has invested $3 million n Power Tagging Technologies Inc., a company that develops smart grid technology.

Colorado-based Power Tagging uses proprietary technology for digitally "tagging" electric power and attached devices. The company said its technology is used for grid mapping, fault isolation, electric vehicle integration, demand side management and grid cyber security, among other things.

Dominion said that, with Power Tagging's technology, utilities would know immediately about changes in electrical flow on the circuit between a customer's home or business and the neighborhood substation, pinpoint problems and needed repairs, and manage specific consumer electricity demand.

Mary C. Doswell, who serves as senior vice president for alternative energy solutions at Dominion, said "We anticipate that for the first time, utilities will be able to measure, trace and audit the flow of electricity on the smart grid in effect, to 'tag' it and follow it with a technology that is embedded in the power grid itself rather than on a parallel communications network." She added that the technology should improve the flow of information and help provide cost and environmental benefits.

Virginia-based Dominion operates a portfolio of more than 27,500 megawatts of generation, 1.2 trillion cubic feet equivalent of proved natural gas and oil reserves, 14,000 miles of natural gas transmission, gathering and storage pipeline and 6,000 miles of electric transmission lines.

Dominion operates the nation's largest natural gas storage systems with 975 billion cubic feet of storage capacity and serves retail energy customers in 12 states.
