First results on an application of Iliceto Shield Wire Scheme to pilot project in Tanzania

Iliceto Shield Wire Scheme (ISWS) is a rural electrification scheme that uses the shield wires of High Voltage (HV) lines, as conductors, and an earth return to provide power at Medium Voltage (MV) to remote villages along the path of the HV line with no other access to the electricity system, at a much lower cost than the traditional methods (new dedicated MV lines). The paper presents the results of an application of this technique to a HV line in Tanzania, Chalinze-Hale-Tanga, identified as pilot project for subsequent realization. The case study has been selected, as pilot project, by the National electricity utility of Tanzania, Tanesco, and analyzed in detail, verifying the technical feasibility. For doing that, a simulation model has been developed and applied. The model is easy and flexible for future modification of parameters and reuse in similar scenarios.
