The Virtual Grid combines prepaid technology with the WakaWaka Power: after a one-time deposit on the WakaWaka Power, weekly scratch cards are bought to activate the unit. The code on the scratch card, along with a unique code from the WakaWaka Power, is sent by text to a free local service number. A text is instantly returned containing an activation code for the unit.
The relatively large pilot will test both the technology and uptake of this service by approaching 9000 households in three districts, and represents a total investment of $2.1 million USD.
