Dhaka: Bangladesh's top business leader has expressed serious concern at the crippling electricity shortfall, saying frequent power cuts had threatened economic activities. 'Production and exports are worst hit by frequent power cuts. I am receiving eight to 10 complaints every day from southeastern Chittagong industrial belt alone,' Yusuf Abdullah Harun, chief of the Federation of Bangladesh Chambers of Commerce and Industry, said at the weekend. He said the government must tackle the power problem urgently. Bangladesh produces 1,700 megawatts of electricity against a minimum requirement of 2,200 MW.
