The rise of e-mobility, new housing developments, the expansion of commercial and industrial areas, as well as distributed renewable energy supply such as wind and solar, will increase capacity and require flexibility of the electrical load in distribution grids. Simultaneously, RNG is faced with the challenge of keeping up and renewing its ageing cable networks while resources are scarce and costly.

To continue improving the quality of supply and increase its capacity, as required by Germany’s federal network regulator (BNetzA), RNG needs to detect potential faults as early as possible and keep downtime to a minimum.
