EGD offers storage bundle units (SBU) , each SBU consists of a combination of working gas volume with injection and withdrawal capacities.

These storage bundles can only be booked on a firm basis.

The storage capacities (working gas volume, injection and withdrawal capacities) can also be booked separately. These unbundled storage capacities enable storage customers to increase the flexibility of storage services.

Unbundled storage capacities may be also booked as interruptible capacity at a reduced price.
