Zambia’s Copperbelt Energy Corp (CEC) will stop supplying power to Vedanta’s local unit Konkola Copper Mines (KCM) from Monday, it said after talks on an extension to their supply agreement broke down over debt owed to CEC. Zambia’s Energy Minister Mathew Nhkuwa told Reuters that KCM would now receive its power directly from state-owned utility Zesco, which has previously sold electricity to CEC for onward supply to KCM.
