Case Study: VSD

Vychodoslovenska distribucna, a.s. (VSD), a key player in the distribution grid in Slovakia, faced mounting challenges related to grid reliability and escalating costs. Non-technical losses in their distribution network, occuring at an increasing rate, were becoming a financial burden and threatening grid stability and customer satisfaction. VSD needed to pinpoint the precise locations of these losses within their grid.

The Awesense team conducted grid measurements to analyze the situation. Without interrupting the power supply, Awesenes deployed the Raptor sensors in a selected area to segment the grid into 13 medium-voltage (MV) and low-voltage (LV) grid segments. From there, they conducted extensive grid measurements for energy balance calculations to identify NTLs within the area.

The project yielded notable results: 129 consumers were measured, and revealed losses exceeding 12,000 kWh during the approximately 27-day measurement period. The Raptor sensors, recording data in real-time, sent grid information to TGI to identify the grid irregularities. VSD validated TGI’s findings by conducting on-site inspections using the TGI mobile app.

The implementation of Awesense Raptor sensors and TGI led to the complete eradication of non-technical losses in the area, with four sites confirmed to be the sources of NTL after in-person inspections. VSD was satisfied with the project:

“Based on the results of the measurements, we managed to reduce the losses in this grid area where the measurements were carried out to the level of technical losses. The approach of the Awesense staff was very helpful, both in the preparation, in the process of installing and uninstalling the meters, and in the evaluation of the project itself.”
