8 Present Policy Context Sector Overview on s Achieve complete electrification through grid and offgrid schemes by 2012 To reach a 10% of electricity from renewable energy resources by 2015 Exploit the full economic potential of energy efficiency improvement To enhance the investment climate in all indigenous energy resources Adopt an integrated planning approach encompassing all above towards a sustainable energy future

9 100% Electrification Policy Sector Overview 100 Accelerated Target on s Households Electrified (%) Off-grid Grid

10 Sector Overview on s Sustainable Energy Authority Sri Lanka Sustainable Energy Authority Act, No. 35 of 2007, and come into operation from 21 st September 2007 Objectives To develop renewable energy resources To declare energy development areas To implement energy efficiency measures and conservation programmes To promote energy security, reliability and cost effectiveness in energy delivery and information management To repeal the energy conservation Act No.2 of 1985.

11 Sector Overview on s The Government will Endeavour to reach a level of 10% of electricity generation using New energy resources by 2015 (it is near 7% today) Availability of Standardized Power Purchase Agreement (SPPA) for less than 10 MW plants. Simple approach What ever produced will be purchased Acceptable to the Banks Low transaction costs Resource allocation First Come first served basis Devoid of cumbersome competitive processes

12 Sector Overview on s Biomass Solar Wind Hydro

14 Energy Portfolio Sector Overview on s Cumulative Energy Capcity Additions MW Year Biomass Hydro Wind Other Total

15 Sector Overview on s Enthusiasm on renewable energy development is high among the local private sector Relatively risk free investment World Bank is operating a special credit line for renewables (RERED). More than 80 projects benefited Carbon trading policies are being developed. pcdm instrument to be developed

16 Sector Overview A Healthy Growth on s

17 Solar Potential in Sri Lanka Sector Overview on s

18 Sector Overview on s Sri Lanka is situated close to the equator, therefore receives an abundant supply solar radiation year around. Solar radiation over the island does not show a marked seasonal variation, though significant spatial differentiation could be observed between the lowlands and mountain regions. As estimated in the solar resource map developed by the National Energy Laboratory (NREL) of the USA, over most parts of the flat dry zone, which accounts for two-thirds of the land area, solar radiation varies from kwh/m2/day. Solar radiation levels remain as low as kwh/m2/day over the high plains of hill country due to the significant cloud cover over most parts of the day. Thus, a substantial potential exists in the dry zone of Sri Lanka for harnessing solar energy

19 Off grid Electrification Policy Sector Overview on s Ultimate Numbers Households Sources of Info Total households without electricity 684,000 SEA survey end 2010 Suitable households for Viduli Athwela 414,000 SEA survey end 2010 Total households without access to grid 270,000 SEA survey end 2010 Households earmarked for RE projects 240,000 CEB indication Households left for off grid 30,000 SEA survey end 2010 Households left for off grid 37,814 As reported by CEB, mid 2010 Households left for off grid (rounded off) 40, ,000 solar home systems lighting up rural homes More than 300 operational village hydro sites serving more than 7000 families by end 2010 Off grid electrification seems to be a matter of declining interest

20 Sector Overview on s Facilitate import and export of electricity through a single, bi directional meter Customers can bank the excess electricity generated and trade the same against future consumption (period of banking 10 years) All consumer categories are eligible (Industrial, Residential, General purpose, Religious)

21 Sector Overview on s Two projects (500kW and 737kW) in the same location Funded by Japanese and Korean Governments First hand experience for local Engineers First phase completed early May kW capacity yielding about 3000kWh per day
