‘Prepaid Electricity Micro Grids for rural Electricity in Tanzania’ by Devergy.

Devergy is a social energy utility which provides a reliable, easy to use electrical service designed to be affordable for low income population not connected to the power grid. The service is based on a plug-and-play village-sized energy microgrid which provides solar power to households and businesses; it allows the users to connect lights and appliances such as radios, TVs and refrigerators.

The key feature of the system is an energy meter that powers the household with a pay-per-use approach, where each user tops up his energy account by buying Devergy credit. Credit can be purchased for the same value of mobile phones credit, and the energy pricing is lower than the designed
to have lower spending than kerosene lighting or commercial phone charging. The installation cost of the energy grid is largely covered by Devergy, except for an affordable fee which is asked at the time of first connection, thus allowing even the lower income customers to access the service.

The customers receive an unprecedented service thanks to a system that is designed to require no user maintenance and that is remotely monitored for faults, so that the reliability and availability of the service is unmatched.

Since the completion of the EEP funded project, Devergy has continued to grow substantially and is planning to extend  their operations also to other regions in Tanzania.

The project inception and implementation is nicely narrated in a short documentary that provides guaranteed smiling by the end.  Click here to see Devergy’s video.
