Distribution Loss

Imagine a water utility where a meaningful share of the water pumped out never actually gets billed, some leaks from old pipes, some is simply stolen through illegal connections. Distribution loss is that exact problem applied to electricity, power lost, technically or through outright theft, between a distribution substation and the final paying consumer.

Distribution losses in India have historically run far higher than in most developed grids, a combination of ageing infrastructure, illegal connections, and inaccurate or absent metering in many areas, and this loss is usually measured together with billing and collection inefficiency as a single combined metric called AT&C loss, Aggregate Technical and Commercial loss. High AT&C losses are the single biggest reason many state DISCOMs remain financially stressed despite selling power at prices that should, on paper, cover their costs.

Reducing distribution loss through smart metering, feeder segregation and better infrastructure has been the central objective of successive government DISCOM reform programmes, since every percentage point cut in loss translates almost directly into improved utility finances without needing to raise consumer tariffs at all.
