Responsibility However Da Afghanistan Breshna Sherkat Dabs Which Was Established In 2008 Under The Corporations And Limited Liabilities Law Of The Islamic Republic Of Afghanistan With All Its Equity Shares Owned By The Government Of Afghanistan Is Responsible For The Operation And Management Of The Electric Power Generation Import Transmission Local Power Distribution And Billing Throughout Afghanistan On A Commercial Basis Afghanistan Has A Population Of 27 66 Million 1 For Settled Areas The Per Capita Annual Usage Of Electricity Is About 195 Kwh Which Is Amongst The Lowest In The World Only 28 Of The Household Is Connected To The Power Supply Systems The Vast Majority Of Whom Live In Urban Centres Rural Power Supplies Continue To Rely On Hydropower With Limited Diesel And Battery Options And Are Estimated To Cover Less Than 9 Of The Rural Population This Lack Of Access Is Significant In Light Of The Fact That More Than 75 Of Afghans Live In Rural Areas 2 According To Power Sector Master Plan Psmp The Net Demand Is Expected To Increase To 15 909 Gwh In 2032 In The Base Case With An Average Annual Growth Rate Of 9 8 According To An Estimate The Actual Present Demand Of Afghanistan Including Served And Unserved Demand Is 5000 Mw Whereas Installed Capacity Domestic And Import Is Nearly 1500 Mw Afghanistan Heavily Relies On Imported Power From The Neighboring Countries Tajikistan Uzbekistan Turkmenistan And Iran Its Imported Energy Contributes 81 To Afghanistan S Energy Mix Mew Forecasts That Approximately 640 Mw Of New Domestic Capacity Will Be Added In The Next Five Years And A Further 1700 Mw In Another Five Years Indicating That Over The Next Decade Domestic Generation Capacity Will Increase By Close To Five Times Current Levels In Mid 2015 There Were 12 Hydropower Plants In Afghanistan Not Counting The Over 5 000 Off Grid Nsp Hydropower Plants The Two Largest Among Those Are Naghlu Hydropower Plant At 100 Mw Installed Capacity And Mahipar Hydropower Plant At 66 Mw Installed Capacity A New 42 Mw Hydro At Salma In Herat Province Was Opened In June 2016 And Work Continues On Developing An Additional 18 Mw Of Capacity At The Kajaki Hydropower Plant In The South Of The Country There Are 9 Thermal Plants Connected To The Grid With A Total Rated Capacity Of Approximately 209 Mw Another 8 Small Plants With An Aggregate Capacity Of 12 Mw Operate Off Grid All Of The Thermal Capacity Is Diesel Fired The Power Generation Mix Is Run To Minimize Costs By Favoring Cheap Power From Abroad And The Use Of Domestic Hydropower Over Thermal And Diesel Power Plants The Government Plans To Continue Increasing Import Capacity Through Projects Set Out In The National Energy Supply Program Nesp The Existing Power System Of Afghanistan Is Operated In Islanded
