Peak supply

According to the Dutch Gas Act, suppliers of household customers must have sufficient resources to deal with the maximum demand associated with a day where the average effective temperature is -9°C. GTS is responsible for supplying the extra gas to household customers at temperatures below -9°C.

In the balancing regime it is not possible to wait for the end of the gas day to allocate the peak supply amounts. As shippers are responsible for balancing their portfolio, it is necessary to allocate the amount of gas delivered by GTS near real time and to adjust the portfolios accordingly. Therefore, the allocation rule is: if during an hour in a portfolio, the sum of all allocations for household customers exceeds the capacity for that portfolio associated with a -9oC day, the excess volume will be allocated to the shippers as a peak supply delivery by GTS. The capacity associated with a -9oC day is equal to the exit capacity that is invoiced in winter (December/January/February).
