The deadlines of the market rules for balancing group billing for electricity (MaBiS) published by the German Federal Network Agency apply exclusively to the processing of balancing group billing:
TenneT calculates the balance deviations of all balancing groups beginning on the 30th business day after the delivery month based on the available, billing-relevant data available by the end of the 29th day after the delivery month. The calculated balancing group deviations are multiplied by the balancing energy price for each ¼ hour, and the balancing group manager is billed accordingly each month.
TenneT issues invoices for balancing energy each month within the framework of the balancing group billing process no later than on the 42nd business day after the end of the delivery month. At the end of the 8th month after the delivery month, TenneT creates and sends a corrected balancing group invoice based on the billing-relevant data available after the end of the 7th month.
You will receive the billing data in accordance with the MaBiS deadlines in MSCONS format in an EDIFACT mailbox which you will name on completion of the balancing group contract.
