Outsourcing important data and processes to a cloud system requires a comprehensive security concept. CoreX employs state-of-the-art standards to ensure that your data is secure.

Thanks to a consistent cloud-first strategy, the CoreX module benefits from the technical possibilities offered by cloud environments today in terms of availability, scalability, security and flexibility.

CoreX provides access to all available cloud technologies for the GAS-X and ENER-GX business modules – without a restrictive cloud vendor lock-in. Physical data separation ensures a secure multi-customer operation.



The Billing module complies with general accounting standards. With regard to accounting systems, this includes in particular the principles of computerised accounting systems (GoBS).

The Billing module coordinates the input from the business modules. Regardless of whether the billing items were created with the Sales, Grid, Storage, BKN or Free Invoice modules or imported as electronic invoices; the Billing module processes these invoice items to generate invoices and posting records.

The design of the Billing module allows it to adapt to your company’s billing processes flexibly and efficiently. A wide range of features support quality assurance, scheduled billing and monitoring processes.


Free Invoice

The Free Invoice module, in combination with the Billing module, serves to create invoices for non-standard business processes.

Use Free Invoice, for example, to invoice default interest and inventory sales, to post incoming paper invoices or simply to correct invoices from legacy systems.

One, two, three, four – use tailor-made features for one-time or cyclical invoices. Positions of one-time invoices are either provided manually or via an imported Excel file. It is also possible to create specific formulas for cyclical invoices.

Generate invoices without the usual overhead. The Free Invoice module does not require contract modelling or quantity object management.



The Sales module consolidates features for offer creation, contract management/billing and planning in a single system. With its integrated multi-commodity architecture, Sales is a future-proof system for the European energy market.

Product-oriented and ultra-flexible at the same time, the Sales module places a strong focus on product-oriented business processes, on one hand, and support for highly non-standard contract scenarios, on the other.

The flexible calculation approach of the Sales module enables easy integration of non-billing processes, such as the evaluation of counterparty risk.

The Sales module provides information such as contract data, time series, and tranche fixations in a customer portal. If you’re already operating a portal, Sales integrates into existing customer portals.



The GDM module automates the energy calculation process, from data retrieval to value export. GDM’s Best View component continually provides values that have the highest possible quality in a given context.

Metering points are the essential objects in the GDM modules and can have a wide range of relations. As a result, GDM can aggregate, compare or reference data and create substitute values easily and efficiently.

Monitoring tools provide a comprehensive overview of the energy determination processes. Such tools include status and progress views for the value calculation processes as well as plausibility and anomaly detection checks.

GDM includes the remote meter reading module ZFA, which fully supports the data retrieval standard DSfG. ZFA is seamlessly integrated into the GDM module. Use ZFA to configure flexible, fully automatic data retrieval routines. The retrievals are carried out via IP, push procedure or GSM connections.



The Grid module can handle all commercial processes for the transport network operator in one end-to-end software solution. The module includes components for contract management, capacity management, nomination management, all allocation processes and billing.

The Grid data model is highly consolidated across the whole process chain, which makes master data interfaces obsolete.

All necessary key figures are calculated by the Grid module – just in time and fully automatically. Extensive Grid monitoring tools ensure you always know what’s going on in your business processes. Integrated APM workflows provide interfaces to the major European capacity platforms.

The Grid module features a flexible export management component to handle market communication tasks. Existing end-to-end processes are supported with different portal applications.



The BKN module covers all essential processes of a market area manager in the German gas market. It enables market area managers to handle their daily and monthly processes on time.

BKN processes and generates market messages, enables the calculation of billing-relevant key figures and prepares the data for the invoice creation process with the Billing module. Data portals are supplied with publication-relevant values.

Due to the high degree of automation, BKN largely works without manual intervention. The module can be run as a cluster, preparing it for the requirements of growing market areas.

BKN provides all structural information about the virtual trading point, entry and exit grids, and grid interconnection points in the market area. This information supports you in the processes of balancing group management, including all necessary communication processes.



The BCM module offers balancing group management for gas suppliers and balancing group managers. Use BCM to plan and trigger capacity bookings, to manage balancing groups and to perform communication and verification processes such as data clearing and shadow accounting.

Balancing group monitoring is a central component in the BCM module. Use BCM to control and monitor balancing groups with daily granularity, regardless of balancing group level, such as: invoice balancing group, sub-balancing account and grid-specific data as well as metering points. The monitoring component for balancing groups takes into account the different quality levels of the data.

In addition to the market processes GaBi, GeLi and KARLA, the BCM module also supports your nomination process with prepared balancing data and by interfacing with forecasting systems.

Use the capacity management component in the BCM module to plan gas transport and capacity booking. Rely on the metering point data provided by BCM to perform communication tasks in the change of supplier business process (GeLi).



The storage module is an all-in-one solution for commercial and technical storage management. Plan, realise and manage marketed storage capacities per customer and storage facility. Storage also manages storage outage notifications, including communication with system operators and your customers.

The technical storage management component of the Storage module serves to manage your operating facilities and measuring points. Features for facility modelling, time series management for metering values and value aggregation are also part of the package.

The commercial storage management component provides features for contract management, account management, storage level management and OBA account management. Use the data curves management feature to process your nomination tasks.

Use the Storage module to monitor storage levels per customer account based on imported nomination data. The Billing module creates invoices for storage usage flexibly and automatically.
