According to a 2016 study, electricity theft and fraud in India can account for almost 20% of the country's total electricity generation. Other sources have reported that the percentage of lost electricity due to theft can range from 20% to 50%.
Electricity theft can be a result of poor governance, and power distribution companies (discoms) that are already in debt can face significant losses. Some say that the government needs to promote better governance in the sector to help manage the issue.
