Current Commodity Charges for Gas Year 2024 - 2025

The commodity unit costs to be applied from 1 July 2024  are calculated using the following formulae:

Commodity Unit Cost (Bacton) (GB to BE flow) in p/kWh = 0.014601422 + [ 0.0000853 * EEX NBP Day-Ahead Price (p/th) ]

Commodity Unit Cost (Zeebrugge) (BE to GB flow) in p/kWh = 0.0102364 + [ 0.0002252 * EEX NBP Day-Ahead Price (p/th) ]



From 1 January 2025 the Be to GB unit cost will be calculated using the following formula: 

Commodity Unit Cost (Zeebrugge) (BE to GB flow) in p/kWh = 0.0046125 + [ 0.0001065 * EPEX BELPEX Day-Ahead (€/MWh) arithmetic average ] +                    [ 0.0002252 * EEX Day-Ahead NBP Price Assessment (p/th) ]

The GB to BE formula will remain unchanged 

Notification of Demand Response Events 

Interconnector will notify all demand response (DR) events via the ENTSOG Transparency Platform here. 

Where a DR event has been called, all nominations of booked Interruptible capacity and overnomination for UK imports (BE>UK) will be reduced to zero for the remainder of the affected Gas Day(s). No further interruptible capacity or overnomination will be offered for the affected Gas Day(s). 

For electricity consumed during the demand response hours Interconnector will incur costs at the negative imbalance tariff as published by the Belgian electricity transmission grid operator, Elia (https://www.elia.be/en/grid-data/balancing/current-system-imbalance). Interconnector may interrupt the BE to UK Interruptible Capacity in order to avoid passing additional charges onto the capacity holders.
