Short description:

The MaKo-Service system is an in-house development at the customer. It performs the query of values from the MDM metering data system, enriches them and prepares the load profile data, energy quantities and meter reading data in the role of metering point operator for star-shaped dispatch in the market. The MaKo service is being further developed for process disconnections.


At the customer's site, the data required for sending market messages (MSCONS) is held in different systems. The MaKo service uses the data from the central master data application (information about the market partners, the metering points and the meter reading dates) and uses this data to determine the measured values from the connected MDM metering data system. The metered values are provided as load profile data or energy quantities for market locations and as meter reading data for metering locations in the Edifact format MSCONS for onward transmission in the market for the customer's own Biztalk server. In addition, the data is forwarded to the internal energy information system.

Technical description:

For the further development of the MaKo service, the following tasks are carried out in the course of the project. Cross-project control, separation of processing according to metering location/market location as well as subsequent requests and time changeover scenarios (delivery of four quarter-hourly values more or less, depending on the time changeover). Furthermore, the necessary supplementary technical processes with regard to complaint, cancellation and fault processes will be implemented, as well as the processes for supplying the internal energy information system with the market-relevant and internal metering data. Within the scope of the project, the productive implementation of the further developments in the MaKo service will be accompanied. Finally, workshops will be held with the customer's internal IT department and the affected specialist departments.
