Implementation of the new market rules for accounting grid settlement
Project duration: 10 months
Brief description
The new BNetzA market rules for carrying out the electricity accounting grid settlement have a major impact on EEG (German Renewable Energy Act) processing by the transmission providers. The project includes designing and implementing the necessary changes to the most important software system used in this context.
Supplement
The transmission provider currently processes the EEG using a Java-based distributed application with the SAP WAS as the application server and Oracle as the database. In the context of new market rules, mechanisms have to be implemented there to import all the EEG feed-in time series according to type and class, delivered by the distribution network operators, to check the plausibility of these and to create crossover time series according to type and class in the transmission provider’s EEG accounting grid. The EEG feed-in from the distribution network operator is to be settled in future on the basis of these crossover time series.
Subject description
According to the Renewable Energy Sources Act (EEG), a transmission provider has the following responsibilities: (a) Discharge and reimbursement of the energy received by the distribution system operators within the transmission provider’s control area, as defined by EEG. (b) Recording the energy received (quantity and chronological sequence) and the reimbursement payments made. (c) Horizontal adjustment: Adjusting the received energy and the reimbursements made between the 4 transmission providers in Germany. (d) Marketing the energy remaining with the transmission provider after horizontal clearing. (e) Proportionate allocation of the accrued costs to all electricity supply companies supplying end consumers within its control area.
