Digital Twin and Predictive Asset Management for Distribution Grids in Delhi: A BRPL Case Study

Delhi’s distribution grid is witnessing rapid growth in air conditioning, EV charging, and rooftop solar, much of which aligns with peak demand, intensifying stress on distribution transformers (DTs) and low-voltage (LV) feeders with limited real-time visibility. DT failure rates of 12–15% are reported in stressed networks due to overloading and thermal stress [1, 2, 3]. Although BRPL reduced its DT failure rate from 0.26% in FY 24–25 to 0% in the first two quarters of FY 25–26 [4], LV congestion and overloading risks persist in dense urban areas.
