Ann: Redflow to deliver ZBM2 batteries for South African Telco, page-11

'Mobax will commence deployment of Redflow batteries at mobile base stations that are currently powered by diesel generators. The ZBM2 batteries will reduce operational costs through less diesel use, lower fuel delivery costs to remote locations and less frequent generator servicing."
This could be ambigious, is the saving by eliminating diesel or reducing it. "less frequent servicing" suggests that the generators are still in place.
