Flexibility services; Combiflex & Balancing service

Combiflex
Shippers can obtain extra flexibility by contracting the combiflex service. With the combiflex service a shipper can increase the hourly-, cumulative and daily tolerance of the basic balancing regime. Combiflex can be contracted on a quarterly basis. This service consists of three elements: production capacity, injection capacity and volume. There are two kinds of combiflex services with different ratios between production and injection capacity. By contracting 1 m3 production capacity a volume of 168 m3 is available. The increase of tolerance applies subject to the availability of sufficient volume. The use of combiflex will be determined afterwards, based on realised imbalances.

We sell and re-sell Combiflex on common basis. The prices and quantities are published on our website. This spreadsheet contains historic publications.

Balancing service
The balancing service involves the shipper transferring the use of a flexible source to the network operator of the national gas transmission grid. Imbalance in the shipper’s portfolio is compensated for on a subsequent basis within the limits of capacity and volume applicable for this source. Use of the balancing service will precede the application of the tolerances in accordance with the balancing regime as well as any booked combiflex.
