Why was the distribution of the AT&C loss determination instead of the T&D loss assessment?
Thus, define the word “AT&C loss.”
Why was the T&D loss assessment changed to AT&C loss determination in distribution? Hence explain the term AT&C loss.

The shift from assessing Transmission and Distribution (T&D) losses to Aggregate Technical and Commercial (AT&C) losses in distribution was driven by the need for a more comprehensive and accurate measure of losses incurred in the electricity distribution sector. The change was necessary to capture not only technical losses (resulting from energy dissipation in wires and equipment) but also commercial losses (caused by theft, billing inefficiencies, and non-payment). This shift provided a holistic view of losses and allowed utilities to identify and address all factors contributing to overall energy loss.
Aggregate Technical and Commercial (AT&C) Loss:
AT&C loss refers to the total percentage of electricity loss incurred from the point of generation to the point of delivery to consumers, including both technical and commercial losses. It is calculated by summing up the technical losses (energy dissipation during transmission and distribution) and commercial losses (resulting from theft, billing inefficiencies, and non-payment).
Technical Losses: Technical losses occur due to inherent resistance in transmission and distribution lines, transformers, and other equipment. These losses result from energy dissipation in the form of heat during the transmission and distribution process.
Commercial Losses: Commercial losses include losses due to theft, metering inaccuracies, billing inefficiencies, and non-payment of bills. These losses occur outside the physical infrastructure but contribute to overall energy loss in the distribution system.
The assessment of AT&C losses provides utilities and regulators with a comprehensive understanding of energy loss within the distribution network, enabling targeted interventions to reduce losses and improve revenue realization. By addressing both technical and commercial aspects of loss, utilities can enhance operational efficiency, financial sustainability, and service reliability. AT&C loss determination has thus become a standard metric for evaluating distribution system performance and guiding loss reduction efforts in the electricity distribution sector.
