Theft and unbilled supply fell from 53% at the 2002 handover to 5.9% by early 2025 — the utility's own figures, for one of Delhi's three distribution circles rather than the whole city.
what does this mean?
The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went.

Since taking over the distribution network of north and north-west Delhi in July 2002, Tata Power-DDL has rebuilt it around metering, SCADA, GIS consumer indexing and outage management to attack electricity theft and unbilled supply. The utility reports aggregate technical and commercial (AT&C) losses falling from 53% at handover to 5.9% by early 2025; a World Bank case study, which puts the inherited loss level at 57%, credits the technology rollout together with a performance-management overhaul and a predictable regulator. The licence area is one of Delhi's three distribution circles, covering roughly 9 million residents — not the whole city, and separate from the neighbouring BSES discoms.
🎓 Lesson
Three sources, three starting points. The utility says 53% in July 2002; its own chief executive, writing on a World Bank blog in 2015, said 53.1%; the World Bank's 2023 case study puts the inherited level at 57%. The direction of travel is not in doubt, but the baseline is, and the baseline is what the headline reduction is measured from. The same case study is careful about what did the work: metering, SCADA and GIS ran alongside a performance-management overhaul, internal processes to stop the utility's own staff facilitating theft, a state government that policed and punished theft, and a regulator with predictable rules that made the capital spending bankable. The technology is the visible part of a settlement that was mostly institutional — which is why the equipment alone has not reproduced the result elsewhere in India.

Independent World Bank case study, document date 1 July 2023. Puts the inherited position in detail: 'AT&C losses were 57 percent due to widespread electricity theft', a billing rate of 54 percent, a collection rate of 80 percent, SAIFI of 55, load shedding of 8 to 12 hours a day and an average of more than 53 days to fulfil a new connection. Attributes the turnaround to network upgrading plus a performance-management overhaul, internal processes to stop staff facilitating theft, state policing of theft, and an independent regulator with predictable rules. The landing page renders only as a JavaScript shell to an automated client; the text was read through the World Bank's own document text service.

CAUTION: hosted by the World Bank but authored by Praveer Sinha, then Tata Power-DDL's own CEO and Managing Director — an operator voice on an independent platform, not an independent assessment. Published 10 November 2015. Gives a third baseline and a capital figure: 'Investments of about $620 million from 2002 until today have led to a reduction in aggregate technical and commercial (AT&C) losses from 53.1% in 2002 to below 10% today', with the Average System Availability Index rising from 70 to 99.55.
