Addressing some issues relating to hybrid mini grid failures in Fiji

Rural electrification, regardless of whichever electrification scheme is utilized (grid extension, mini grids, or autonomous energy home systems) has many potential benefits. In particular, hybrid mini grid power systems are potentially highly valuable electrification scheme for remote rural electrification in comparison with other electrification schemes but they involve significant complexities in terms of design, implementation, and operation and maintenance. This implies that there are many challenges that have to be overcome before the benefits of hybrid systems can be achieved. A detail literature review and targeted consultations with a range of Fijian stakeholders were undertaken to better understand options for addressing some of the technical as well as the non-technical issues leading to the failure of hybrid mini grids in Fiji. Key findings suggest that lack of proper documentation on systems, carrying out system designs in isolation, failure to incorporate learnt from previous projects into newer projects and failure to understand the system and limitations; all are the contributing factors for an unsuccessful and unsustainable hybrid mini-grid in Fiji. Finally, this paper suggests some useful guidelines for successful and sustainable hybrid mini grid systems.
