ZESA announced that they now accept USD payments when buying electricity. You can walk into a ZESA branch with your USD and hand it over to the cashier and you will be given a token. You can also use Inn Bucks and Eco Cash USD to pay. They do not really bill you in USD, they just convert your USD to ZW$ at the prevailing interbank rate at the time of purchase. So, if you walk into a ZESA branch with USD cash, that is what will happen. It is the same when you use Inn Bucks or Eco Cash, you are not really using USD. They convert your USD to ZW$ at the interbank rate too and then process your transaction. ZESA only charge RTGS for Domestic Customers but if you go and buy ZESA using USD they convert it to RTGS using the prevailing interbank rate on the day. ZESA said domestic users are not charged USD meaning some corporates/organisations are charged.
