These conditions are: • • • • • • • •
The tariff for an orientation study; The tariff for a detail study ; The tariff for the use of a connection bay ; The tariff for the use of lines or cables and its requisites ; The tariff for the use of equipments for transformation, compensation of reactive power and filtering of the voltage wave ; The tariff for the use of supplementary protection-equipments, supplementary equipments for alarm signalisation, metering, supplementary equipments for centralised teleactions and/or telecontrol ; Reduction coefficients on the connection tariffs for production units based on renewable energy sources with limited predictability ; Reduction coefficients on the connection tariffs for auto-production units insofar as an offtake is located on the same access point.
The tariff for an orientation study The tariff for an orientation study for either a new connection or for the adaptation of an existing connection is a one-shot whose amount depends on the nominal power to connect. The amounts of the tariff are published in the table below: Nominal power to connect (P) P< 25 MW 25 MW <= P < 50 MW 50 MW <= P < 100 MW 100 MW <= P
One-shot tariff € 2250,00 € 4500,00 € 9000,00 According to specifications
The tariff for a detail study The tariff for a detail study for either a new connection or for the adaptation of an existing connection is a one-shot tariff depending on the level of the estimated cost of the connection considered in the study. The tariff for the detail study of an investment, of which the estimated cost is smaller than € 100.000,00, is individually determined according to specifications. The tariffs for the detail study of investments, of which the estimated cost is situated between € 100.000,00 and € 2.500.000,00, are fixed following the table mentioned underneath:

For investments of which the estimated cost is higher than € 2.500.000,00 the tariff for the detail study is € 7.500,00 + (0,006 x the estimated cost of the investment). The charged tariffs for the detail study are reduced of the connection cost in case the realization of this connection is ordered in its totality. For grid users producing increased levels of disturbance and wishing for a connection in conformance with stadium 3 of the technical reports IEC 61000-3-6/7, additional studies, named “power quality studies”, need to be executed. In this case the following tariff, depending on the nominal power of the installations to be connected, is being charged: - Pnom < 20 MVA : € 4.000,00 - 20 MVA <=Pnom<=80 MVA : € 8.000,00 - Pnom > 80 MVA : € 12.000,00 The charged tariff for “power quality studies” cannot be reclaimed when the connection is ordered. The tariff for the use of the connection bay The tariff for the use of the connection bay consists of • •
a yearly charge to put the connection bay at disposal of the grid user a yearly charge to operate and maintain the connection bay.
These yearly charges, whose amounts are mentioned in the summary table further in the text, give the grid user a right to use the total functionality of the connection bay including preservation and replacement.

Charges to put an existing connection bay at disposal of the grid user is adapted, on a proportional way, in order to reflect the financial interventions taht the grid user has done in the past, relating to this connection bay. This adaptation is valid until the date of replacement of the connection bay and not longer than 33 years after the date the connection has been put into service.
The tariff for the use of other connection equipments: lines or cables and their requisites, equipments for transformation, compensation of reactive power and filtering of the voltage wave 1. Charges to put a new connection (or the adaptation of an existing connection) at disposal of the grid user The amount B, representing the total amount of investment, is determined according to specification. The first part of the amount B (this is the amount B1) is covered by a one-shot payment, depending on the agreements Elia has made with its suppliers. This compensation must be paid not later than the moment the connection will be put into service. The requester of the connection is free to chose the amount B1 insofar the proportion B1/B does not exceed 20%. The grid operator proposes the payment schedule for this tariff, following the chronological evolution of its expenses for this connection. The difference (this is B2 = B – B1), if there is one, is paid on the basis of yearly constant payments: •
•
A first part of this amount (this is the amount B2g) is object of constant periodical payments (annuities) and of a bank guarantee on first demand, which has to cover the outstanding balance of the total amount B. The annuities are calculated on the basis of the duration of the industrial project and with an interest rate equal to the WACC (the weighted average cost of capital) of ELIA; The difference (this is the amount B2r = B2 - B2g) is covered by constant periodical payments (annuities). This part doesn’t need to be covered by a bank guarantee. The annuities are calculated on the basis of the duration of the project and with an interest rate (i) equal to the WACC of ELIA, increased with a risk premium (S) for the concerned grid user or his ‘portefort’ following the formula: i =WACC + S*B2r/B2.
The grid user is free to chose the amounts B2g and B2r insofar the proportion B2r/B2 does not exceed 50 % and insofar B2g+B2r+B1 equals B.
