Landis+Gyr releases Gridstream MDUS 1.0 to enable end-to-end business processes with SAP

July 8, 2010 – The latest release comes after Landis+Gyr and SAP last year announced their cooperation on the development of a state-of-the-art meter data unification and synchronisation (MDUS) system that integrates Landis+Gyr’s smart metering system with SAP’s comprehensive business software for utilities.

Gridstream MDUS from Landis+Gyr performs two-way communication with SAP for Utilities®. It enables end-to-end business processes by providing two-way access to smart metering data directly from the SAP ERP. Up-to-date consumption data is available in the business system and on-demand readings and connect/disconnect services can be managed without logging in to a separate smart metering system.

Gridstream MDUS covers functions and interfaces required for meter validation and estimation, network management, billing, and customer relationship management. It provides one central short- and long-term data repository for all energy measurement data. Gridstream MDUS is interoperable with third-party Head End Systems that use an IEC standard-based interface.

Gridstream MDUS 1.0 includes the following interface functionalities via SAP AMI 1.0 webservices:

  • Meter Reading at scheduled times, or on demand
  • Master Data Synchronization at meter installation and register changes
  • Basic Interval Data services for transferring metering time series information
  • Configuration Data
  • Disconnection / Re-connection of meter’s status by operating the meter connect-relay

The range of services is continuously evolving, as Landis+Gyr and SAP share a joint development path in R&D to help utilities manage energy better.

Gridstream MDUS is based on open software architecture. This enables easy integration to the utility’s smart grid applications and ensures a future proof solution. The software can be expanded to support any Head End System following industry standards, and the utility can build also the meter park on several suppliers’ products.

Landis+Gyr’s smart metering solution, Gridstream, offers a complete portfolio of meters, standardised communication technologies and software for multi energy smart metering. The complete end-to-end solution ensures seamless flow of information and provides tools for personal energy management and network management support; forming the foundation for the smart grids.
