In November 2011, the diesel generators at the new Hera Power Station became operational, producing 119 MW. This replaced the operations of the Comoro station, with Hera able to produce electricity using 17% less fuel. A new substation was created to supply Dili, and transmission lines link Dili to other cities and towns along the northern coast, part of a ring surrounding the country. As of 2016, Dili's peak power demand reached 42.11 MW. The development of electricity infrastructure since independence has significantly reduced electricity costs, which moved from 249c per kilowatt-hour in 2002 to 5c per kilowatt-hour in 2014.
