Learn MoreFiji is a small island developing state and its numerous geographically dispersed islands present unique challenges for 100% electrification. Solar PV can help establish distributed systems to provide electricity to un/underserved population.
Hence, for this work grid storage is not considered. At present, Energy Fiji Limited (EFL) is responsible for providing grid electricity generation to four different islands (Viti Levu, Vanua Levu, Ovalau and Taveuni) where each one of them have their own grid network and power generation stations.
Solar PV has been in use in Fiji for almost three decades. One of the first use of solar PV was in solar home system (SHS) that provided electricity to power basic appliances in rural households where grid electricity was not reachable. Currently, there are two types of SHS installed in Fijian homes.
In total, around 4 MW of solar PV is installed with some grid-connected solar systems planned and many off-grid solar system planned by Fiji Department of Energy with funding from Fijian government and overseas donor agencies.
Forty percent of the daily demand is met by the solar mini-grid on each island (Engerati 2015). The annual energy output from Kadavu solar-diesel mini-grid system is 319 MWh, while it is 217 MWh/year each for Lakeba and Rotuma. These systems were installed by Sunergise with financial support from the Abu Dhabi Development Fund (ADFD).
According to the annual reports of Energy Fiji Limited (EFL), there has been some solar electricity generated from 1998 to 2007 by solar PV system that was commissioned in November 1997 (FEA 2016). In 1998, this system generated around 12 MWh of electricity and was doing well for almost 6 years.
