Invoicing and tariffs
Use of the Elia grid and the available ancillary services is subject to a set of tariff conditions, which are regulated by CREG and reflected in the invoicing.
For injection and offtake of electricity, access holders are subject to the regulated tariffs applying to the volumes measured at the access points to the Elia grid.
Elia offers a range of additional metering services (commercial services) for market players, and issues quarterly invoices for these services.
Elia issues quarterly invoices covering the tariffs regulated and approved by CREG for the construction, substantial modification, provision and management of connections to the Elia grid.
Elia relies on BRPs (Balance Responsible Party) to maintain the balance in their respective control areas. Each BRP is responsible for maintaining, on a quarter-hourly basis, the balance between all offtakes and all injections in its balancing perimeter. If an imbalance is detected, an imbalance tariff is applied.
