(openPR) - Cuculus and ckc have integrated the ZONOS smart meter solution to work with an unbundled SAP IS-U system. The proof of concept covers all process steps required to upgrade customers from traditional tariffs to smart metering tariff plans. This includes all installation and set-up steps including making the information available so customers can view their consumptions data in a secure environment on their personal web portal.

Many smart metering projects are currently in the transition from pilots to real larger scale implementation. This frequently requires integration to SAP IS-U or other core systems. Such integration is critical to reach acceptable operational costs levels and assure data consistency for smart metering implementation. The integration starts by providing data sets for metering points to a MDM like ZONOS as well as the monthly read meter levels from the MDM to SAP IS-U.

The integration was done by using SAP EHPs 3 and 4 (AMI 1.0) which requires the implementation of some of the processes which are expected to be part of the MDUS concept in SAP AMI 2.0. Netweaver PI/XI and enterprise services were used to enable SAP to trigger meter inventory synchronization, meter installation jobs, on demand meter reading jobs and update of user data to grant access to the Smart Metering web portal. In the other direction ZONOS is sending meter level data, alarms and other useful messages to provide management information to the customer operations team. Data, jobs and responsibilities within SAP were distributed according to the market role rules required to guarantee strictly unbundled operations between a grid operator and an energy supplier.

Within this cooperation, Cuculus is responsible for providing and adapting the ZONOS-MDM platform, while ckc is responsible for data integration and process integration of ZONOS and SAP IS-U. With the resulting set-up SAP works with the ZONOS platform with the different head-end systems, older meter reading solutions or meters directly are connected to the ZONOS. ZONOS streamlines all data structures, protocols and processes on a common interface.

Cuculus and ckc are well prepared for integration projects based on the MDUS concept, but can also work with older EHPs of SAP. The proof of concept can be demonstrated with live meters and metering data.

A second integration project will take place during the second quarter of 2011. In this project Cuculus and ckc have been asked by an utility client to fully integrate ZONOS Smart Home solution with the client’s SAP system.

Cuculus GmbH offers software solutions for Smart Metering, Smart Home and Smart Grid.
