It is based on a common, consistent model of the grid structure. As a specialized form of a Geographic Information System (GIS), it is commonly applied by utilities and disposal companies.

European differences: Using a NIS as an upgrade to a conventional GIS is very common, especially in northern Europe (e.g., Sweden and Norway).

Distribution grid operators use network information systems to digitally capture and manage their power grids. It contains complete information on:

• lines
• switching stations
• secondary substations
• service connections

— all geo-referenced with precise location data and enriched with technical details.

Network information systems are often linked to other systems, such as grid control systems or planning tools. It serves as the digital foundation for operations, maintenance, and grid planning.

For distribution grid operators, data quality in the NIS is critical: Incomplete or outdated information directly affects the accuracy of grid calculations, investment decisions, and the implementation of legal requirements such as Section 14a of the Energy Industry Act (EnWG), Section 9 of the Renewable Energy Sources Act (EEG), or Redispatch 2.0.

Tip: In combination with envelio’s Intelligent Grid Platform, a NIS can be used as a data source for a consistent, computable grid model. This way, asset data stored in the NIS can be directly integrated into digital workflows — from grid compatibility testing and state estimation to strategic target grid planning.

Another advantage: With envelio's IGP, NIS data can be combined with information from the meter data management system (MDMS), so that time series and smart meter data are included in planning processes.
