The Energy Regulation Board has approved a tariff increase of 75% for all customer categories except mining and exports. The increase will be implemented in two phases, with an initial 50% effective on 15 May 2017 and a further 25% on 1 September. The government has come under pressure to end subsidies and move to cost-reflective tariffs as Zambia battles a widening fiscal deficit. Zesco requested the tariff increase in March.
