Asian Development Bank (ADB) is proposing to extend USD 115 million loan to Sri Lanka’s power sector for supporting electricity supply reliability improvement to Ceylon Electricity Board (CEB). The loan will focus on identifying the hybrid renewable energy (wind and solar) mini-grids in Analaitivu, Delft and Nainativu Islands in Jaffna peninsula, medium voltage network in ten administrative districts of the country, rural electrification schemes in sixteen districts, and renewable energy based pilot microgrid for evacuation of renewable energy (solar) projects and overall improvement of network efficiency. 2. The components of the Supporting Electricity Supply Reliability Improvement Project will consist of four components. Component 1: Renewable energy systems development 1.1 Hybrid renewable energy systems in small isolated islands 1.2 Productive energy use for small isolated islands and rural communities 1.3 Renewable energy micro-grid system Component 2: Reliability improvement of the medium voltage network Component 3: Rural electrification and distribution performance monitoring improvement Component 4: Reactive power management in the transmission system 3. Hybrid renewable energy mini-grid systems have been proposed in three islands, Delft, Nainativu and Analaitivu, all located off the western coast of Jaffna peninsula. Delft Island, the largest of the three, approx 50 km2, situated about 10 km from mainland, is the second largest island situated within the territorial waters in Sri Lanka. The Delft National Park, 1846.28 ha, declared on 19th June 2015, by the Department of Wildlife Conservation for conservation of wild horses is situated in the southern part of the island and it occupies about 37% of the land area. The land identified for the hybrid system is about 800 m outside the National Park and belongs to the government. 4. Productive energy use for small isolated islands and rural communities will promote and strengthen energy-based livelihoods through access to electrical appliances and technologies,
