Development of an EEG settlement system

The EEG application helps to record and calculate infeed and output to and from a transmission provider's transmission network, in the context of the EEG. The resulting energy flows are mapped in schedules. Furthermore, all the data required to settle the monthly advance payments and create the end-of-year invoices is identified.  An integrated letter action tool controls correspondence and electronic notification. The Java application is designed and implemented as a "fat client" solution (2-tier) but it fulfills the requirements for a simple migration to a "rich client" solution (n-tier). This migration shall take place subsequently, with SAP WebAS 6.40 to be used in the framework of NetWeaver 04.
