Pulaski, TN, U.S.A. --- (METERING.COM) --- August 27, 2008 – Pulaski Electric System (PES) has selected TUNet® – the Tantalus Utility Network – for its advanced metering infrastructure (AMI) communications system, which is at the heart of its smart grid program. PES is an electric utility located in southern Tennessee that serves 15,000 electric customers and 5,000 Fiber-to-the-Home (FTTH) customers of PES Energize.  

The Tantalus communications system gives Pulaski the option to use either its existing high-speed FTTH network or 220 MHz RF for two-way, real-time data transport. This allows PES to drive additional value from its FTTH, as well as extend smart grid functionality to outlying areas of the community via the wireless TUNet wide area network.

TUNet is an end-to-end WAN / LAN / HAN data communications system that operates with both RF and IP-based networks including FTTH, Fiber, WiFi, WiMAX and GPRS/cellular. WAN options can be used individually or be combined to meet a utility's economic, coverage and redundancy needs.

The 900 MHz LAN enables a utility to precisely monitor consumption and power quality, automatically pinpoint outages and energy losses in real time, and remotely manage meters and other apparatus, even in challenging urban, rural and industrial environments. It is smart grid technology that provides the data needed for timely billing, optimal system performance and progressive conservation initiatives, including load shedding and customer signaling via the Web or an in-home display so that consumers can make informed decisions on when they purchase energy.

"We're a service driven utility," said Ron Holcomb, CEO of PES. "Before we made our decision, we needed to be convinced that this technology would enable us to bring value to our customers by allowing us improve our operational efficiency and prepare for effective demand response with time-of-use pricing.

"We chose TUNet because it's a communications network and application suite built for the future...one that addresses much more than metering. It will enable us to implement demand response and energy efficiency programs and in-home displays as needed and to whatever degree desired without starting over or retooling the entire network. This clears the path for adopting a full range of smart grid services and creating a distribution system in which consumers and utilities play an active role in reducing both consumption and costs."
