RALEIGH, N.C., Aug. 27 /PRNewswire/ -- Continuing efforts to provide safe, reliable and cost-efficient services to its electric and natural gas customers, Alliant Energy has selected the Sensus Metering Systems FlexNet AMI system to implement advanced metering infrastructure across its entire service territory, in the states of Wisconsin, Iowa, and Minnesota. Subject to regulatory approvals, the deployment is set to begin in Wisconsin starting in the 4th quarter of 2007 and includes more than one million iCon smart electricity meters and 400,000 FlexNet AMI endpoints installed on existing natural gas meters. "We performed a thorough evaluation of available technology and believe that FlexNet offers a core set of advantages that will enable us to cost effectively meet our aggressive near-term objectives, while positioning us to be able to offer beneficial advanced services and rate offerings to our customers in the future," said Barb Siehr, Alliant Energy's Vice President of Customer Service and Operations Support. The FlexNet system will allow Alliant Energy to leverage its prior investment in an extensive array of communications towers already in place for voice communications. In addition, the primary licensed frequency in which the FlexNet system operates provides the most protection over the long term, and enables Alliant Energy to transmit at up to 2 watts of power, thus reducing the infrastructure needed to support its three state (54,000 sq. miles) service territory. Alliant Energy will benefit from the system's flexibility and utilization of a single fixed base technology for areas within their service territory where they provide electric and/or natural gas services. In addition, because FlexNet is a tower-based AMI network, Alliant Energy will be prepared to accommodate future growth as it expands meter deployments. "We are pleased that Alliant Energy selected the FlexNet technology and look forward to a successful partnership," said Dan Harness, president of Sensus Metering Systems. "Central to the design of the FlexNet system is advanced functionality and ability to perform in a variety of rural, urban and suburban environments, both aspects that make FlexNet the perfect fit for Alliant Energy."
