Invoice legend

  • Contract reference number

    This is the reference number of the connection contract signed with Elia. Elia sends the connection invoice to the grid user. If the grid user has not yet concluded a connection contract with Elia, the access holder is responsible for making connection payments on the grid user's behalf. In such cases, Elia sends the connection invoice to the access holder, quoting the reference number of the access contract that includes the access point(s) associated with the connection(s) in question.

  • Your reference number

  • Elia’s internal reference number

    This is the internal reference number used by Elia. It is different from the contract reference number.

  • Invoicing period

    Connection payments are settled on an annual basis, in line with the connection tariffs. These tariffs are approved by CREG for a four-year tariff period. The exact amounts of the connection tariffs are adjusted on a yearly basis, with the amounts for the four coming years being set at the beginning of each four-year tariff period.
    Connection payments are invoiced on a quarterly basis – namely during the first month of the relevant quarter – once the connection has been commissioned.

  • Payment for investment

    Annual payments are made to Elia to cover investment (or CAPEX) relating to the construction, provision and, if applicable, substantial modification of the connection facilities. These payments are detailed in Appendix 6 to the connection contract.
