Zambia’s attempt to force Copperbelt Energy Corp (CEC) to open up its infrastructure to other power producers has dented the country’s image as an investment destination, the Chamber of Mines said on Friday. Energy Minister Matthew Nkhuwa issued a decree last Friday compelling CEC to allow others to transmit electricity via its infrastructure. Though it can negotiate terms, CEC said the energy regulator had also cut the tariff it can charge to 30% of the current price.
