Eritrea - Solar PV Mini-Grids for two Rural Towns and Surrounding Villages
Eritrea’s energy supply system is characterized by massive dependence on traditional biomass fuels to cover its domestic energy requirements, a lack of easy access by the majority of the country’s population to modern energy; and total reliance on imported oil as a source of modern energy. Less than 10% of Eritreans in rural areas have access to electricity. Therefore, an effort by the Ministry of Energy and Mines and international donor organizations is made to promote rural electrification through sustainable sources.
The present project included the design and tendering of two mini-grid PV systems in Areza and Maidma (total 2.25MWp PV), designed as hybrid plants with storage units (3.4 MWh Li-Ion Battery), and diesel gen-sets (5 gensets; total 1.3 MVA). The renewable energy fraction of the system is higher than 70%. The local distribution grid was designed and tendered by Eritrea Electric Corporation and the generation side was handled by intec.
