Day-ahead trading

With day-ahead trading on electricity and gas exchanges, the gas or electricity is supplied and paid for the following day.


The German Technical and Scientific Association for Gas and Water (DVGW: Deutscher Verein des Gas- und Wasserfaches) is responsible for producing a set of technical rules which ensures the security and reliability of the gas and water supply. The rules also apply to the thermal quantity determination of natural gas. As a member, GASCADE is involved in producing the DVGW’s sets of rules.

Dynamically allocable capacity (dac)

With dynamically allocable capacity, the entry or exit capacities have an assignment restriction. This means that only very specific network points can be reached and the capacity is fixed. Access to the virtual trading point is only possible on an interruptible, “as available” basis. See also interruptible capacity, fixed capacity and freely allocable capacity.
