SAP Energy Data Management

EU-wide harmonization of the gas sector puts new requirements on IT-supported business processes

The energy policy of the European Union pursues the objective of an EU-wide, unified gas market. By the intended liberalization and harmonization of the single markets the competitive pressure increases, since formerly nationally operating companies get active also abroad. Moreover, there is a need for action for the gas companies in order to implement the European regulatory requirements at the IT level. Especially in Eastern Europe there is a high demand for efficient solutions to implement business processes duly and market role-specifically in the respective SAP system.

Germany takes a pioneering role here. An example for that is the basic model for compensatory payments and accountancy rules in the gas sector (GABi Gas 2.0). In many European countries market roles such as Distribution System Operators, Transport System Operators or Suppliers are already defined, but there is a high need for adaptation, for example in case of the network codex of the European Network of Transmission System Operators for Gas (ENTSOG). In addition, increasing quality demands regarding data exchange processes between the various market partners arise, which further increase the requirements for the SAP Energy Data Management (SAP EDM). So flexible solutions for the implementation of business processes to the SAP EDM are needed, that are compliant to the market role specific rules of the companies in the gas sector. On the one hand such solutions must ensure the energy supply, on the other hand they must enable the companies a transparent cost control and high data quality.

Sustainable allocation management
In some countries Distribution System Operators need regulatory required functionalities to perform a correct allocation determination in order to identify the temperature-dependent daily consumption of customers that are not interval metered. For this purpose coefficients for different customer groups, calendar information and temperature data are required. Therefore weather data can automatically be downloaded from a weather data service provider and transferred to the SAP EDM for a proper calculation of the consumption.

The increased demands are particularly evident by the EU regulation that requires to convert the gas consumption from cubic meters to kWh performing a Technical Quantity Determination (TQD) based on the calorific value and the gas volume. This represents a major challenge for many Distribution System Operators. Since several grids with different calorific values can inject into one interconnection point with a different network in behind, the Distribution System Operator must convert the received data. For this, a comprehensive calorific value management is needed. Apart from the data import and the calorific value determination, a calorific value management must also include updating processes for billing and reference calorific values. The possibility to calculate the compressibility by a complete molar gas analysis is also of advantage, insofar as this is allowed by the technical equipment of the Distribution System Operator. In this way a conversion of the operating volume of the gas into the standard volume can be made and afterwards the amount of energy can be determined automatically. A calculation of the conversion factor is also necessary for the following processes.

Representation of the grid topology
For the Transport System Operator (TSO) on the other hand, the representation of real existing network interconnection points such as transfer stations between two grids or entry- and exit points at gas storages is important in order to plan the gas supply as efficiently as possible. Therefore you need a comprehensive capacity and nomination management that enables the TSO to represent the current grid situation. For this purpose information concerning the capacity situation at the respective interconnection points must be available, such as the particular, technically maximum capacity and the capacity booked per shipper or supplier.

The focus of the gas supplier is the adequate supply of the customers who are bound by contract. To that end the required amounts of energy per market area must be nominated at the virtual trading point. In order to ensure high-quality data here, the forecast of the expected gas consumption as well as the validation of the time series received from the market partner is essential.

Avoidance of double settlements
In order to meet these complex requirements, PROLOGA has developed the solution “SAP EDM, add-on for gas regulatory compliance“ specifically for companies in the gas sector. It is an enhancement of the SAP IS-U and maps the functions of the allocation, nomination, capacity or balancing group management, among others via intuitive functions. The solution also provides utility companies with comprehensive monitoring functionalities to analyze the master data quality.

For balancing group managers, the solution provides a balancing group monitor that displays the received settlement results in a graphical and hierarchical form. Incoming messages regarding the balancing group status are processed automatically. Furthermore, many other gas-specific market communication formats, e.g. defined by EDIG@S like CAPNOT, CAPRES, DELORD, DELRES, IMBNOT, NOMINT, NOMRES, TRANOT or SSQNOT, are integrated.

By the complete integration in SAP IS-U, the “SAP EDM, add-on for gas regulatory compliance by PROLOGA“ ensures consistent business processes and allows gas companies the efficient implementation of regulatory requirements, in order to remain competitive with customer-oriented processes, even in the liberalized, EU-wide harmonized gas market.
