The telegestore project in ENEL's metering system

Abstract
This paper presents telegestore, an innovative system by ENEL Distribuzione to manage residential and commercial meters remotely via low voltage grid. Telegestore exploits low voltage distribution network between concentrators and meters; public GSM and network between acquisition centers and concentrators. Key factor of this architectural choice is the availability of data transmission link (DLC) at each customer point without requiring any additional physical infrastructure. Solutions for gas and water have been implemented and tested because ENEL is committed to offer integrated multi metering solution in the next future. In addition to Lontalk enhanced protocol, ENEL has recently reintroduced its proprietary HDLC protocol for data transmission. (4 pages)
