In the early years of UN rule, electricity was provided by the Comoro power station, which has a 16 MW diesel generator. By 2004, there were 23,000 connections in the city creating a demand of 12.5 MW. At the time, Dili was the only location in East Timor with 24 hour electricity. Electricity demand peaked from 19:00 to 22:00. By 2009, Comoro was producing 32 MW, and by the year after that 92.3% of Dili's households used electricity for lighting purposes. Cooking remained carried out using firewood by 66.2% of households, with electricity being used by just 10.1%. Non-payment of electricity bills has caused some funding problems. In 2011, only 40% of commercial recipients of electricity paid their electricity bills.
