The Stadtwerk Hassfurt is a supplier of electricity and water to the city of Hassfurt, with more than 13,000 inhabitants. The public utility of Hassfurt awarded the contract to Echelon’s NES value-added reseller partner EVB Energie AG to provide all of its approximately 10,000 customers with an advanced metering infrastructure over the next three years. Germany recently proposed a new energy law requiring all new and remodeled homes to be equipped with smart meters by 2010 to promote energy conservation and efficiency.
The NES advanced metering infrastructure from Echelon consists of a family of highly integrated, advanced electronic electricity meters accessed via a web services based network operating system over an IP networking infrastructure. Unlike systems with a dedicated radio per metering point, multiple NES meters can share a single IP connection through the use of Echelon's proven standards-based power line networking technology. This drives down the per-point connection cost and enables the system to easily and cost-effectively incorporate new wide area networking technologies over the life of the system. The system’s open interfaces allow the system to be cost-effectively expanded, adapted, and customized in ways unlike any competing system .
