Add-On Service

Additional to existing contracts, working gas volume, injection capacity or withdrawal capacity can be contracted separately to align your storage portfolio with your specific needs.

Properties

The service is an additional service to our primary flexibility services. By contracting additional capacity or volume, the properties of the service can be fine-tuned to meet your specific requirements. Therefore, the Add-on service has the same specifications as the underlying primary service.
