eMeter & SAP

SAP invited eMeter, as a strategic vendor of Smart Grid management solutions, to join the Lighthouse Council in 2007 as one of the original members to help shape and define their utility solution. The result — standard enterprise web services for Meter Data, Unification, and Synchronization (MDUS) that join eMeter EnergyIP, the leading Meter Data Management platform, and SAP for Utilities, the leading enterprise system for energy companies.

eMeter is aligned with the strategy of standard interfaces between MDUS and SAP IS-U. eMeter has many implementations today which integrate EnergyIP with SAP including CPS Energy, First Energy, Vattenfall, ODR, Umetriq and Bluebonnet.

eMeter and SAP

Key Functionality of the SAP MDUS Integration Pack

With eMeter EnergyIP, you can quickly turn your data into actionable information that can be leveraged across the utility. eMeter provides two SAP MDUS Integration Packs, one for SAP IS-U Enhancement Pack 4 and one for SAP IS-U Enhancement Pack 5. The Integration Packs support the MDUS integration and web services that are delivered with these SAP releases.

Key Functionality

Master Data Synchronization

Master Data Synchronization
As new meters enter the system, or data on existing meters is modified, SAP will trigger a web service to EnergyIP. EnergyIP receives this message and synchronizes this data. [see video]

Device Installation & Provisioning

Device Installation & Provisioning
After the installation of a meter, SAP will send EnergyIP the installation details. EnergyIP will create the relationship records tying the meter to a particular service point and location (note that SAP will also notify EnergyIP of a meter removal so that the relationships can be ended). Once the meter has been installed and EnergyIP has completed the provisioning process, a notification will be sent back to SAP with the information that provisioning has been completed. [see video]

Meter Read Data Delivery

Meter Read Data Delivery
A variety of transactions in SAP will trigger a meter read request from EnergyIP such as move-in / move-out [see video], cycle billing, off-cycle reads, control reads, etc. EnergyIP will receive this information and create a request in the Billing Services application. Once the Billing Services application fulfills the request, the adapter will send the appropriate value back to SAP to complete the process. Requests can also be cancelled in the event that the read is no longer needed.

On-Demand Meter Reads

On-Demand Meter Reads
In addition to requesting a meter read for a specific date, SAP can also trigger a request for an on-demand read. When EnergyIP receives such as request, a message is sent to the meter via the Activity Gateway for a meter read. Once the request is fulfilled, the result is returned to SAP. [see video]

Interval Data Delivery

Interval Data Delivery
Interval data can be pushed on a regular basis to the SAP. Interval data goes through the Validation, Estimation, and Editing process in EnergyIP. Valid or Estimated interval values will be sent according to how the schedule is set up (e.g. daily). SAP receives this data and stores the values in the Energy Data Management component of SAP at which point the interval data is available for further processing in SAP. [see video]

What’s New for Enhancement Pack 5

The eMeter SAP MDUS Integration Pack for Enhancement Pack 5 is built on the AMI Integration functionality delivered with SAP IS-U Enhancement Pack 5 (EhP5). In addition to the functionality in the Integration Pack for EhP4, thirty-one new services have been added in EhP5 to support the expanded capabilities of the MDUS integration. These new services enhance the existing data synchronization and meter data consumption capabilities as well as adding new functionality.

Key functionality with EhP5 includes

Synchronization Capabilities

Enhanced Synchronization Capabilities
Additional services have been added to support synchronization of new objects. Key among these is services
that support sending Premise data and Device Location data. The ability to link devices is also possible. This will be useful for linking a communication module to a device or CTPTs. A tighter link with the Energy Data Management (EDM) module is also established in this release.

Data Consumption Capabilities

Enhanced Meter Data Consumption Capabilities
With EhP5, utilities will no longer be required to pass interval data to SAP Energy Data Management (EDM). An option exists to request framed usage data according to the TOU bins or critical peak times. Agents will have the ability to view interval data from the MDUS if required, for example, to analyze a rate or view the details behind a TOU bin. Interval data can continue to be replicated in SAP if desired.

Meter Commands

Meter Commands
Additional web services are available that support connection status change and operational state check. If a meter has these remote capabilities, a connection status change request or an operational state check initiated in SAP will be sent to the MDUS. The MDUS will route this request to the appropriate AMI head-end and upon execution of this request, the MDUS will send back the information to SAP to complete the process.

Event Handling and Text Messaging

Event Handling and Text Messaging
New functionality will be available to handle events coming from the meter. Certain event data will be sent to SAP for further action. Additionally, the ability to send a text for display in an in-home device will be available.
