How Delhi cut its electricity losses from 50 to 5 percent

In 2002, Delhi lost half its electricity to theft and broken wires. Today, its grid outpaces parts of Europe.

Writing in IEEE Spectrum, a power systems professor detailed how Delhi overhauled its grid over two decades. The city cut power losses from over 50 percent in 2002 down to 5 to 6 percent in 2026. Structural utility reforms, modern equipment, and replacing overhead lines with underground cables pushed grid reliability from 70 percent to over 99.9 percent.

Why it matters: Grid loss creates a death spiral. When utilities lose half their power, they lose the revenue needed to fix decaying infrastructure. Delhi broke that cycle for 23 million residents, offering a working model for cities across Brazil, Kenya, and Bangladesh facing similar distribution losses.

Know this: Delhi’s 5 percent loss rate now matches France and Belgium, even while handling a peak demand of 8,748 megawatts.

Turns out fixing basic grid infrastructure pays off.
