Remarks:

For off-take covered by local generation, the price for the subscribed power is reduced with 30%. This reduction is applied to a maximum power of 75 MW. This contractual formula is only applicable for yearly subscriptions and is limited to 1000 hours per year. For the mobile charges of the railway company, the price for subscribed power is reduced with 7%.

b) Tariff for additional power 1) On annual basis Table 2 : Tariff for additional power on annual basis according to the “standard formula”

Clients directly connected to the Elia grid Tariff (€/kW.year) 1,9883000 2,9765000 5,2861000

Grid Operators Tariff (€/kW.year)

The additional power on annual basis is monthly ex-post determined as the maximal peak for a running year (month of performance M up to month M-11). 2) On monthly basis The additional monthly power is ex-post registered by Elia as the difference between the maximal peak of the past month for the considered tariff period and the total subscribed power for that month of that period. The price equals 115% of the price for power subscription according to the monthly scheme, during the corresponding period. Remark:

For the mobile charges of the railway company, the price for additional power is reduced with 7%.

3° Tariff for power subscription and additional power, according to the “Day / Night and weekend formula” For the application of the tariffs for subscribed power and complementary power, according to the « Day / Night and weekend » formula, the tariff periods « Day » and « Night and weekend » have been defined as follows: • •

Day : from 8h to 20h, Monday to Friday (60 hours per week) Night and week-end : from 20h to 8h (Monday to Friday) + Saturday and Sunday, whole day (108 hours per week)

This formula will be applied under following conditions : • •

For each access point, the Access holder chooses between the « standard formula » or the « Day / Night and weekend » formula. These possibilities are mutually exclusive. The choice of the « Day : Night and weekend » is valid for one year. The offtake from the concerned access point has shown a profile (during the preceding year of the choice), such that : o The maximal power offtaken during “Day” hours was smaller than the maximal power offtaken during “Night and Week-end”; o The energy offtaken during “Day” hours is smaller than 25% of the energy offtaken during “Night and Week-end” hours.

Remarks: •

Elia System Operator makes quarter-hourly deliveries of reactive power that exceed tg ϕ=0,329 per off take point. This leads to a term for supplementary deliveries of reactive energy, according to the article 209 §4 and §5 of the Technical Code. Table 8 :

•

In the case the offtaken active energy does not exceed, on a quarterly basis, 10% of the valid subscriptions at any given point, the additional delivery of reactive energy will be defined as the excess in respect of 32,9% of the 10% of the valid subscriptions at that point.

•

In the case in offtake regime, the capacitive reactive power doesn’t exceed the following limit values, tariff for supplementary deliveries of reactive energy equals 0€/kVArh.

C. DEFINITIONS RELATIVE TO ENERGY The gross limited power, on an access point for a given quarter of an hour, is the difference, if positive, between the offtaken power by the load(s) connected in this access point and the injected power by the local generation(s) associated to this access point, and this for the part of the injected power by these local generations that is smaller or equal to 25 MW. In case the before mentioned difference gives a negative value, the gross limited power is equal to 0. The gross limited energy, on a given access point for a given period, is the integral of the gross limited power in this access point for the given period. In other words, if • Pload(qh) is the average offtaken power by the loads on an access point for a given quarter of an hour qh, and • Pgeneration(qh) is the injected (produced) power by the local generation(s) associated to this access point on the given quarter of an hour qh, the gross limited energy, for the period per, equals E gross _ lim ited ( per ) =

∑ max(0; P

ch arg e

qh∈ per

(qh) − min( Pproduction (qh);25MW )).

The net offtaken power, on an access point for a given quarter of an hour, is the difference, if positive, between the offtaken power by the load(s) connected in this access point and the injected power by the local generation(s) associated to this access point. In case the before mentioned difference gives a negative value, the net offtaken power is equal to 0. The net offtaken energy, on a given access point for a given period, is the integral of the offtaken power in this access point for the given period. In other words, if • Pload(qh) is the average offtaken power by the loads on an access point for a given quarter of an hour qh, and • Pgeneration(qh) is the injected (produced) power by the local generation(s) associated to this access point on the given quarter of an hour qh, the net offtaken energy, for the period per, equals E offtaken ( per ) =

∑ max(0; P

qh∈ per

ch arg e

(qh) − Pproduction (qh)).

24/12/2009

Remark If the injected power by the local generation(s) equals 0, the net offtaken energy coincides the gross limited energy. Example For a load of 100 MW (for a given quarter of an hour), and an injection of 40 MW by a local generation associated to this load:

Off-take by the charge = 100 MW

Injection by the local production = 40 MW

For the given quarter of an hour: • Net offtaken energy = max( 0, 100 MW – 40 MW) * 15 minutes = 15 MWh • Gross limited energy = max( 0, 100 MW – min(40 MW, 25 MW)) * 15 minutes =18,75 MWh.
