The Energy Regulation Board (ERB) has raised power tariffs for mining companies by 28.8% from 2 April after almost three years of dispute involving state power utility Zesco and mining companies. Most mining companies in Zambia buy electricity via the private Copperbelt Energy Corporation (CEC). Zesco was pushing to increase power tariffs for mines to $0.078/kWh from $0.0531/kWh but the ERB only allowed a rise to $0.068/kWh. The ERB has raised mining tariffs twice since 2007 – a period in which non-mining tariffs increased by a cumulative 96% on average.
