Hi, We provide FTTH and FTTA (Uncapped MTN Fixed LTE).
All our FNO'S has backup power solutions, to provide uninterrupted service during loadshedding.
Obviously they can run out of power from time to time in certain areas, depending on the situation.
MTN may not have backup power on all their Towers, however most of them do, so you might see some performance impact in loadshedding for LTE services
I hope this has answered your question,
