Capacity split rules

The above-mentioned monthly capacities are calculated in line with the rules on splitting capacity between different timeframes. The rules are described here: Split Rules. These rules were approved by the relevant regulators.

Net Transfer Capacity (NTC) (Ref. 1)

The Net Transfer Capacity (NTC) is the transfer capacity forecast agreed between Elia and its neighbouring transmission system operators (TSOs) for imports and exports across Belgium’s borders.

Visit Transmission capacity at borders for more information on the calculation mthod.

Proposed capacity (Ref. 2)

In accordance with the above split rules, the “proposed capacity” is calculated before yearly capacity resales are included in the monthly auction.

Capacity for auction (Ref. 3)

“Capacity for auction” is the sum of the proposed capacity and the resales of yearly capacity to the monthly auction. Monthly capacities are sold on the market via explicit auctions organised by JAO.EU, the joint auction office set up by a group of TSOs (including Elia).

Visit Cross-border mechanisms for more information on current mechanisms.

Capacity Calculation methodologies differ between time horizons

The long term (Year, Month & Week) capacity calculation is based on an NTC methodology while the daily capacity calculation process is based on the Flow-Based methodology. Forecast capacity for import and export in Elia’s control area will be influenced from both time horizons and methodologies. More information on the calculation methods is available here “methodology”.
