Wind and Solar Energy Power Potential Wind Power Resource Map Solar Energy Resources Map Spatial Distribution of Global Horizontal Radiation(GHI): varies from 1250 The Exploitable Technical wind power potential kwh/m2/year on the humid highlands to with wind power capacity density above 8 MW 2100 kwh/m2/year in high potential regions per sq km is estimates as 5650 MW mainly in Taking into consideration the land availability 01/12/2014 the North Western and Central regions the exploitable solar is estimated as above 6 6000 MW
Small Hydro and Biomass Potential Average Annual Rainfall Spatial Distribution of Land identified for Energy Plantations The total estimated small hydro potential is Sri Lanka Renewable Energy Master Plan 873 MW with an annual energy generation Study undertaken by RMA with the assistance potential of 3,061 GWh. Out of this of ADB indicates that potential for electricity potential, 253 MW of capacity was in generation using grown biomass is 2,370 MW, operation by the end 2013 (SEA, 2014) and out of which 1,319 MW will be from dedicated the capacity realisable from this total energy plantations and the remaining 1,050 MW potential 01/12/2014 is estimated to be approximately of capacity will be from mixed crops under 7 400 MW in the medium term various commercial plantations
Hydro Potential in Sri Lanka Hydro Thermal Share in the Recent Past Hydro power is the main indigenous renewable energy resource available in the country for electricity generation Almost all the economically viable hydro potential has been developed. The Government has put the highest emphasis on development of remaining hydro power projects in the country. At present 35% of the annual energy generation comes from hydro plants
Non Conventional Renewable Energy Non-conventional Renewable Energy sources received (NCRE) a new impetus in 1996, when the Government announced Standardized Power Purchase Agreement and standardized tariff for private developers of NCRE based power plants of capacity less than 10MW. It further boosted up by the introduction of cost based technology specific tariff in 2007 By December 2013, a total of 136 small private power producers connected to the grid with 367 MW of installed capacity 01/12/2014 9
Challenges in Development of Renewable Energy 01/12/2014 10
Major Issues/Barriers Grid interconnection issues have not been adequately addressed e.g. system stability, spinning reserve needs, grid penetration levels, power quality, etc. Already a considerable amount of embedded generation (367MW) through mini hydro/wind plants which are not under system control operations. This strongly limits the further addition of varying source of power such as wind. There is strong need for continuing on going resource assessment activities for reliable data.
Daily Load Demand The Load Curve Low growth rate of off peak load could result energy curtailment and system stability issues with high penetration of variable renewable energy loads during off peak hours
Proposed Remedial Actions for High Penetration of Renewable Energy Sources 01/12/2014 13
Introduction of Pump storage Improve the efficiency of the base load plants such as Coal due to the off-peak restrictions by filling the valley of the Load curve. Feasibility is being done. Demand Peak Load Peak Demand 4,717MW How to Manage 1,320MW Middle Load 2,000MW Base Load Time Daily Load Curve Projection in 2025
