Short description:

Updates on the German market rules for carrying out the accounting grid billing in the electricity sector (MaBiS) require the processing of further data, initially for (but not limited to) direct marketing. In the project, additional data structures for the associated supply and transfer time series as well as metering points including the associated interfaces will be created and the integration of this data into the implemented billing processes will be implemented.


The transmission provider processes the EEG using a Java-based distributed application with the Apache TomEE application server and Oracle as the database, and on their customers' side within their EEG-Internet web portal based on the Apache Tomcat web server as well as another Oracle database.
