GEORGIA POWER INSTALLS MAJOR COMMUNICATION SYSTEM FOR DISTRIBUTION AUTOMATION AND AUTOMATIC METER READING AT 1996 OLYMPIC SITE

 SAN CARLOS, Calif., May 13 /PRNewswire/ -- Domestic Automation Co. (DAC(R)) announced today that Georgia Power Co., a subsidiary of the Southern Co. (NYSE: SO), has begun installation of DAC's CellNet(TM) communications system to support distribution automation, automatic meter reading and demand-side management applications within the service territory being readied for the 1996 Summer Olympics in Atlanta.
 During 1993, the system will be integrated into Georgia Power Co.'s new SCADA and Automatic Mapping and Facilities Management (AM/FM) systems as part of their EPRI Utility Communications Architecture (UCA(TM)) demonstration.
 DAC's CellNet system adheres to open architecture principles. This allowed Georgia Power Co. to procure RTUs from their preferred vendors (Valmet and Energyline), interface to their new SCADA system (Valmet OASyS(TM)) over IEEE 802.3 ethernet and run their Southern Co. protocol (SES-92).
 During the first phase of this project, a distributed UNIX-based network management and application management system has been installed to provide utility departments with direct access to all of the devices attached to the CellNet system. RTUs will connect directly to the CellNet system's 9QPR digital radio network. This 900 MHz licensed radio network supports parallel cellular operations to create a scalable network and narrowband modulation techniques to optimize channel bandwidth efficiency.
 SCADA applications supported through the CellNet system include overhead switch control and line monitoring. The CellNet system's capacitor bank control application allows distribution operators to remotely monitor and control capacitor banks as well as program internal control strategies in field units. In addition, feeder performance data can be collected for trending analysis.
 Later in the year, CellNet-compatible Landis & Gyr residential meters will be installed to support automatic meter reading and remote connect/disconnect applications. Meters will connect to the PowerLAN(TM) network, the CellNet system's spread spectrum radio-based metering network. The goal of the metering project is to improve billing reliability, reduce meter reading costs and prove the economic viability of widespread automatic meter reading using the CellNet system.
 DAC is a leader in two-way, fixed-point, wireless data communications. DAC's initial focus is working with the utility industry to implement real-time monitoring and control of utility distribution networks encompassing customer metering sites, switches, transformers and other system elements. DAC equipment, including its metering products, is in use at over 100 utilities across the United States.
