Understanding Non-Technical Loss (NTL)

Non-technical loss (NTL) encompasses energy losses due to unauthorized consumption, meter tampering, and billing irregularities. These losses not only impact utility revenues but also burden honest consumers with higher costs. Tackling non-technical loss is essential for maintaining the financial health of utility companies and ensuring fair pricing for all customers.
