Tantalus is partnering with Marietta Power and Water, Georgia’s largest municipal utility serving more than 45,000 electric and 17,000 water and wastewater customers, for the implementation of a fully automated, two-way smart grid solution. TUNet is increasing the return on investment of Marietta Power’s existing Itron, Inc. ERT® (encoder receiver transmitter) AMR technology by remotely collecting and processing electric, water and gas readings in near-real time with a hybrid IP and wireless-based AMI network.
Within months since deployment began, Marietta Power is now remotely collecting meter readings from more than 36,000 electric and water ERT devices through TUNet, translating into significant economic benefit from streaming consumption data across the organization, reducing field visits and reducing operational costs associated with manual metering.
“We reached a point in our smart grid strategy where we were ready to take the next step from basic meter reading to advanced applications that drive measurable ROI,” said Ron Mull, General Manager for Marietta Power and Water. “For Marietta Power and Water, the most favorable path forward was to utilize as much of our existing investments in ERT technology as possible, while moving to a more real-time network that could support applications such as voltage monitoring, remote disconnect and outage management. We set a goal to implement AMI to improve our operating performance and reliability through integrated advanced applications, and we’ve been pleased to see that Tantalus has proven capable of matching our pace in both technology implementation and support.”
Marietta Power will be able to fully automate the remote collection of daily and interval electric and water meter readings by overlaying its service territory with a low-maintenance and cost-effective TUNet system while upgrading less than ten percent of its installed meters. The utility also plans to leverage a number of advanced data-driven features delivered through TUNet, such as improved water leak detection. Additionally, TUNet is integrated with existing billing interfaces, allowing the utility to leave current billing processes and meter reading routes unchanged.
Marietta joins more than 20 municipal and cooperative utilities, including Garland Power & Light (TX), Coldwater Board of Public Utilities (MI) and Piedmont Municipal Power Agency (SC), who are now implementing this unique, low capital cost ERT-reading technology which enables a migration from existing AMR to AMI and advanced applications. These utilities represent just a fraction of the significant installed base of ERT technology deployed throughout the United States.
