The Parliament of Zimbabwe passed two Acts, the Electricity Act 2002 and the Rural Electrification Fund Act 2002, which ushered in comprehensive reforms in the electricity industry. These reforms have already started accelerating Zimbabwe's power sector development and expansion. The new Electricity Act, allowed for the establishment of the Zimbabwe Electricity Regulatory Commission (ZERC) and the restructuring of the Zimbabwe Electricity Supply Authority (ZESA) into a Holding Company.
