tl;dr: Delhi slashed electricity losses from over 50% in 2002 to 5-6% today by privatizing distribution (splitting the state utility between Tata Power and BSES), deploying SCADA systems, capacitor banks, insulated cables, and digital meters, while enforcing India's 2003 Electricity Act to prosecute theft. Reforms also included community engagement in low-income areas—hiring local women as bill collectors—and organizational restructuring with better-trained staff. Grid reliability now exceeds 99.9%, and the approach offers a blueprint for other cities in Argentina, Bangladesh, Pakistan, and elsewhere struggling with decrepit distribution infrastructure.
HN Discussion:
  • ↑Personal testimony confirming dramatic improvement in Delhi's power reliability over the years
  • •Interesting unintended side effect: insulated lines became highways for monkeys
  • ↑India should further leverage solar, batteries, and rooftop/vertical panels to build on progress
  • ~Surprise/skepticism that Estonia is cited as having grid problems given its tech reputation
  • ↑Comparative examples where poor incentive structures (Greece) prevent fixing losses
