The solution
India's distribution companies were the weak link in an otherwise expanding power system, with combined annual losses of INR 678 billion and cumulative debt of $83.5 billion. West Bengal needed to strengthen its grid while preparing for more renewable and distributed power.
The West Bengal Electricity Distribution Grid Modernization Project paired traditional works with the grid's digital layer: high-voltage distribution systems, underground cables, smart consumer meters, SCADA, ERP and distribution automation technologies.
The World Bank reported that the project improved distribution infrastructure for about 90 million people across 14 districts. By September 2024, smart meters and advanced digital systems were serving over 60,000 consumers, with a target of more than 400,000 residential consumers by November 2026.
What it achieved
Digitize the grid's nervous system
Why it worked
Smart meters attacked the billing and collection problem that often outlives physical upgrades.
SCADA and automation gave operators visibility before the grid had to absorb more variable supply.
Combining AIIB and World Bank finance kept the technical package large enough to cover 14 districts.
Institutional capacity building was part of the design, not an afterthought.
What can be applied
Grid investment pays back better when wires, meters and operating software arrive as one package. Otherwise new capacity can still leak revenue and reliability.
Aftermath
AIIB's 2026 project page still listed the operation as active, with a January 2026 field visit. The World Bank said the West Bengal project aimed to extend smart-meter and digital-system benefits to more than 400,000 residential consumers by November 2026.
