There are several reasons for Aggregate and Commercial losses, which include Overloaded Lines/Transformers, use of equipment like lines/transformers having high technical losses by design, Low Power Factor, Low HT/LT Ratio, lengthy lines, faulty Meters (Slow/Not working), power theft, billing inefficiencies, collection Issues like inadequate modes/ inconvenient collection timings etc.

The responsibility for reduction of AT&C losses in the Distribution network rests with the State Power Departments/Utilities. However, Government of India has launched various schemes such as Integrated Power Development Scheme (IPDS), Deen Dayal Upadhyaya Gram Jyoti Yojana (DDUGJY), National Electricity Fund (NEF) and Ujwal Discom Assurance Yojana (UDAY) to enable States to improve their Distribution infrastructure systems so that energy loss including those due to pilferage are reduced.
