I. INTRODUCTION
Energy security is a multifaceted concept that is often used as an umbrella term encompassing theinterconnectedaspectsofanenergypolicy.Sovacool(2012)definesitas,“…equitablyprovidingavailable,affordable, reliable, efficient, environmentally benign, proactively governed, and socially acceptableenergyservicestoendusers”andfurtherdefinesfour“interconnectedcriteriaordimensions”:availability,affordability, efficiency, and stewardship. Vivoda (2010) proposes an energy security assessmentinstrumentcomprising11dimensionsand44attributes.InconsultationwithdozensofexpertsinAsiaandelsewhere,Sovacool(2011)hasidentified20dimensions.Scheepersetal.(2006)notetheneedtodevelopsecuritysupplystandardsfortheEuropeanUnionanditsmembersandsuggestamodelthatincludes two quantitative indicators—the supply/demand index and the crisis capability index—andsomequalitativeconsiderations.Supply/demandincludesfinalenergydemand,production,transport,andprimaryenergysupply.Crisiscapabilitycombinestheriskofsupplyinterruptionswiththecapabilitytoovercomethem.Inbothcases,theindexesarequantitative,buttheycombineobjectiveinformation(such as energy balances or checklists) with subjective information (weighing factors, scoring rules).Theycanbecombinedviasimpleaddition(whetherweightedornot) intoasinglesecurityofsupplyindex.
In this paper, energy security means self-sufficiency and diversification, energy sustainabilitymeans energy efficiency and low carbon emissions, and energy (electricity) affordability is measuredastheratioofthecostofelectricitytopercapita income.SecuritythuscorrespondswithSovacool’savailability, and sustainability combines his dimensions of efficiency and stewardship (protecting thenaturalenvironment,communities,andfuturegenerations).Thisdefinitionofsecuritymayberegardedasnarrowasdiversificationisusedasaproxyforresilienceorresistancetoshocks,butitispurelyforthepurposeofquantification;widerdefinitionsarealsojustified.
We calculate energy security, sustainability, and affordability from 2010 to 2035 for AsianDevelopmentBank’s(ADB)AsiaandPacificmembersusingprojectionsfromtheADB(2013)business-as-usual (BAU) scenario for five indicators: primary energy intensity (PEI), carbon dioxide (CO2)intensityoftheprimaryenergymix(CIX),energyself-sufficiency(ESS),theaffordabilityofelectricity(EOL),andprimaryenergydiversification(DIV).Theseindicatorshaveanumberofkeyproperties:

Reserves decrease using the consumption rate, not the production rate, and do not accountforexports.Thereareseveral reasons for this.Fromapractical standpoint,exportsare impossible toforecast accurately, and estimating export levels is feasible but controversial, particularly in the longterm.Fromaconceptualviewpoint,exportsoffersomecompensationinexchangeforthefuturelossofself-sufficiency.

III. INDEXES FROM 2010 TO 2035
We computed the indicators from 2010 to 2035 for ADB Asian members using the projections formacroeconomicandenergyparametersfromtheADB’s(2013)business-as-usual(BAU)scenario.
A. Energy Sustainability
The sustainability of a national energy system is measured using PEI which summarizes the energyefficiency of the economy as a whole, and CO2 intensity of CIX which indicates the environmentalperformance of the energy system. In general, the energy efficiency of an economy increases as itdevelops, thus the PEI in most will decrease usually by more than 20% from 2010 to 2035 (Figures1, 2, and 3). Those with the highest intensities in 2010 (Figure 1) will experience the most dramaticimprovements, e.g., Bhutan, the People’s Republic of China (PRC) Myanmar, Turkmenistan, andUzbekistan.NoteworthyexceptionstothisaretheKyrgyzRepublicandMongolia(Figure3).
Remarkably,theCIXwillincreaseinmosteconomiesfrom2010to2035(Figures4,5,and6)astheenvironmentalperformanceoftheirenergysystemsdeteriorates.Inless-developedcountries,fossilfuelswillincreasinglydisplacetraditional,carbon-neutralfuelssuchasbiomassandagriculturalresidueswhichofferscertainadvantages(dependabilityandbetterindoorenvironments)butincreasesnetCO2emissions.TheCIXdecreasesmoderatelyinthedevelopedgroup(Australia,Japan,andNewZealand)from2010to2035(Figure6).TheRepublicofKoreahasthelargestreductionat20%duetogreateruseofCO2-freesourcessuchasnuclearandrenewables,butitisneverthelesssmall;themaincontributiontotheoverallreductioninCO2emissionscomesfromimprovementsinPEI.

In the developed group (Australia, Japan, and New Zealand) the ESS will decrease except inJapan where the larger contribution of renewable energy (mainly wind and solar) will improve self-sufficiency.TheDIVhashighvaluesin2010andwillchangeonlyslightlyfrom2010to2035(Figure8).
InEastAsia,theESSwilldecreasesubstantiallyinthePRC(Figure8).InHongKong,China;theRepublicofKorea;Mongolia;andTaipei,China,theESSshowslittlechangefrom2010to2035.ExceptinthePRCandMongolia, theESShasvery lowvalues indicatingasignificantdependenceonenergyimports.TheDIVshowslittlechangeexceptinthePRCwhereitincreasesduetogreatercontributionsfromgas,nuclear,andrenewables(windandsolar).

Figure13demonstratesthataffordabilityisdirectlyrelatedtoeconomicdevelopment;ingeneral,it will improve, as development improves (Figures 14–18). Some factors can decrease affordability,notablyintroducingnewandmoreexpensivepowergenerationtechnologies,ariseinfuelprices,andthedepletionoflocalreservesrequiringimports.
In Central Asia, Armenia, Azerbaijan, Georgia, and Kazakhstan will considerably improveaffordability (Figure 19) as they experience significant economic growth from 2010 to 2035 that willdecreasetheirEOL;however, theirelectricitysystemsarebasedondifferentresources.ArmeniaandGeorgia have negligible fossil-fuel reserves; power generation is based on hydro in Georgia and on acombination of hydro and nuclear energy in Armenia. Azerbaijan and Kazakhstan base their powergenerationonindigenousgasandcoal,respectively.IntheKyrgyzRepublic,Tajikistan,andUzbekistan,economicgrowthisnotsufficienttosubstantiallyimproveaffordability.
Inthedevelopedgroup,affordabilitywillremainnearlyconstantandevendecreaseslightlyinAustralia(Figure19).Japanwillincreaseitsshareofrenewables(windandsolar)inthepowersystemwhich translates into a higher overall LEC; however, this will be offset by economic growth and by areductioninfossilfuelimports.AustraliaandNewZealandwillincreasetheirsharesofnaturalgasandrenewables in power generation which will result in a higher LEC in 2035, but economic growth willreduce the impact on affordability. Australia, Japan, and New Zealand will have the highest share ofrenewables(windandsolar)inthepowersectorin2035at16.1%,27.6%,and27.4%respectively.
InEastAsia,affordabilitywillimproveconsiderablyeverywherebutespeciallyinMongoliaandthePRC(Figure19).Powergenerationinbothcountriesin2035willbebasedonlocalcoal,althoughinthePRC,thecontributionofcoalwillbereducedfrom78%in2010to58%in2035duetotheincreasedpenetrationofnaturalgas,nuclear,andrenewables.InHongKong,China;theRepublicofKorea;andTaipei,China, the power mix will change only moderately; coal will be reduced in favor of natural gasand nuclear in the Republic of Korea; natural gas and renewables in Taipei,China; and natural gas inHongKong,China.AlthoughtheoverallLECinEastAsiawillincreaseduetothegreatercontributionofnaturalgasandrenewables,substantialeconomicgrowthwilloffsetitbyalargemargin.

IV. THE BENEFITS OF INTEGRATION
We calculated aggregate indicators for each region in a similar manner to assess the implications onsustainability,security,andaffordabilityofregionalpolicies,andofregionallyintegratedenergysystems.
A. Sustainability
Whencomputedasaregionalaggregate,PEIwilldecreaseforallregions(Figure21)exceptforthePacific(Fiji,PapuaNewGuinea,Timor-Leste,andotherPacificislands).Thisdecreaseissubstantialinregionswithhighenergyintensitiesin2010,i.e.,CentralAsia,EastAsia,SouthAsia,andSoutheastAsia.Inthedevelopedgroup(Australia,NewZealand,andJapan),thereductioninPEIwillbequitemodest.

D. Benefits of Integration
Based on the foregoing analysis, this section summarizes the benefits afforded by integrating energysystemsregionallyintermsofbothsecurityandaffordability.
1. Security
FromtheanalysisofESS,CentralAsiaoffersthemostdistinctbenefitsforregionalintegration.Consideredseparately,theESSofmosteconomieswilldecreasesubstantiallyfrom2012to2035,buttheaggregateregionalsecurityindicatorwillremainhighduetothefossilfuelreservesinAzerbaijan,Kazakhstan,andTurkmenistan. InEastAsiaandSouthAsia,theaggregateESSindicator is largely influencedbythePRCandIndia,respectively.InEastAsia,regionalintegrationcanimprovethesecurityoftheRepublicofKoreaandofTaipei,Chinaespeciallyregardingcoal.LargecoalreservesinthePRCandMongoliacanhelpmeetdemandfortheshareofcoal intheirprimaryenergymixtobe16%and27%in2035,respectively.AparallelsituationisinSouthAsiawherelargecoalreservesinIndiacanhelpimprovetheenergysecurityofSriLankawhosecoalshareintheprimaryenergymixwillbe24%in2035.AfghanistanandPakistanwillimprovetheirenergysecuritywithbetterintegrationwithCentralAsiawhichhasimportantoilandgasreserves.DespitethesignificantfossilfuelreservesinIndonesiaandMalaysia,inSoutheastAsiaESSwilldeterioratesignificantlyfrom2012to2035evenasaregionalaggregate.
Inthedevelopedgroup,thelargecoalanduraniumreservesinAustraliacanimprovetheenergysecurityofJapanwhosecoalandnuclearshareintheprimaryenergymixin2035willbe24%and4.5%,respectively.InthePacific,thefossilfuelreservesofPapuaNewGuineawillimprovetheenergysecurityofFiji,Timor-Leste,andotherPacificislands.
Another noticeable benefit of regional integration would be an increase in the diversificationof the power systems (Figure 26). In most areas, the diversification of the power sector is largerregionally than nationally. In Central Asia and Southeast Asia, the improvement in diversification isquitenoteworthy.Someeconomiesbasepowergenerationlargelyonasinglesource(forinstancecoalin Kazakhstan, natural gas in Turkmenistan, or hydro in Tajikistan). Aggregating national systems notonlyincreasesdiversificationbutalsoresultsinabalancedpowersectorwithmostoftheconventionaltechnologiescontributingsignificantlytotheaggregate.
Integratingnationalpowersystemsintoregionalsystemscanhaveadvantagesinadditiontothatofincreaseddiversification.Thelarge-scaledeploymentofintermittentrenewableenergy(e.g.,windandsolar)posesadditionalchallengesformanagingpowersystems(suchasfollowingdemandorregulatingfrequencies). Regionally integrating the power grid renders the system more manageable for largersharesofrenewables(e.g.,morethan20%).Countrieswithalargeshareofrenewables(e.g.,Denmark)needhigh-capacity,internationalpowergridinterconnectionstomanagethesystem.InAsiancountrieswithalargefractionofhydropower(Bhutan,theKyrgyzRepublic,theLaoPDR,Myanmar,Nepal,andTajikistan), regional integration will help avoid the effect of dry years on the energy system and willassistwiththeharmonizationofcompetingusesforinlandwater(e.g.,powerinwinterandirrigationinsummer).

2. AffordabilityRegional integration would alleviate the cost of importing fuels for island economies (Maldives; SriLanka;Taipei,China;andTimor-Leste)without indigenousfuelresources ,andforthosewhosefossilfuel reserves will be depleted by 2035 (Afghanistan, Bangladesh, Japan, the Republic of Korea, andPakistan).Inthoseeconomies,theregionallyaggregatedlevelizedelectricitycost(LEC)islowerthanthenationalLEC(Figure27).Economieswithfossilfuelreserves(Australia,Azerbaijan,BruneiDarussalam,Indonesia, and Mongolia) or those with hydropower systems (Bhutan, the Lao PDR, Myanmar, andNepal)willnotimproveaffordabilitythroughregionalintegration.

A. Impact on Sustainability
Asageneraltrend,thePEIforAsiaandthePacificin2035islessinACS–BAUthanintheBAUscenario(Figure33)becauseGDPgrowth isusually fasterundertheACS–BAUhypothesesandPEIgenerallydecreaseswithdevelopment.ThePEI is,however,greater inACS–BAUthan inBAU inpartsofEastAsia(thePRC;HongKong,China;RepublicofKorea;andTaipei,China);andinCentralAsia(Armenia,Kazakhstan, Tajikistan, Turkmenistan, and Uzbekistan). Except for the PRC, this is because growth isfasterintheBAUscenariothaninACS–BAU.InthePRC,economicgrowthisslightlyfasterinACS-BAUthaninBAU,butsoistheincreaseinenergyconsumption.Asaconsequence,thePEIinthePRCis3.9%higherinACS–BAUcomparedwithBAU.TheoverallPEIinAsiain2035doesnotchangesignificantlybetweenACS–BAU(276toeper$1,000)andBAU(278toe/$1,000).
Inmosteconomies,thePEI isslightly lowerinACS–ALTthaninACS–BAUduetoadditionalenergy efficiency measures; however, the differences are very small (Figure 34). The main exceptionis Cambodia where the PEI in 2035 is higher under ACS–ALT. This is because economic growth inCambodiaisgreaterunderACS–BAU.

VII. CONCLUSIONS AND POLICY RECOMMENDATIONS
A. Sustainability
ThePEIwilldecreaseaseconomiesdevelopinlinewithuniversaltrends;additionaltargetedpoliciesmayaffordadditionalimprovements.TheCO2intensityoftheCIXwill,however,decreaseonlyinEastAsiaandthedevelopedgroup.InotherADBmembersitwillincreaselargelyduetothecontinuingdisplacementofcarbon-neutralfuels(suchasbiomass)withmoreconvenientfossilfuels.Additionalpolicieswillberequiredtodecreasethecontributionofoilandcoalinfavorofgas,nuclear,andrenewables.
CoalisthefossilfuelwiththelargestreservesintheregionandthereforeisthemaincontributortoCO2intensity.IntheBAUscenario,thecoalcontributiontotheprimaryenergymixwilldecreaseonlyslightlyfrom46.4%in2009to40.2%in2035;andtheoilcontributionwillremainvirtuallyunchangedat24.6%in2009and24.1%in2035.ThesemoderatereductionsarethereasonforthepoorperformanceoftheCIXindicator.

B. Security
TheESSintheregionwilldecreasesubstantiallyfrom100%in2009to59.8%in2035.Currentoilreserveswillbedepleted(evenwithoutexportsoutsidetheregion)by2019,andgaswillnearlybedepletedby2035.Japan,however,willmorethantripleitsESSindicatorfrom0.05currentlyto0.17in2035duetoincreasedrelianceonrenewablesources(windandsolar).
Oilandshalegasmaythereforeplayan importantrole inmaintainingenergyself-sufficiency.Additionally,theregionpossessessubstantialuraniumreserves(Australia,thePRC,India,Kazakhstan,Mongolia,andUzbekistan)thatarenotbeingutilized.

C. Affordability
ElectricityaffordabilitywillimprovesubstantiallyastheeconomiesinAsiagrow.By2035,itwillincreasebymorethan20%inmostandby50%ormoreinArmenia;Bhutan;Cambodia;thePRC;Georgia;India;Indonesia;Kazakhstan;theLaoPDR;Maldives;Mongolia;Myanmar;PapuaNewGuinea;Singapore;SriLanka;Taipei,China;Tajikistan;Turkmenistan;andVietNam.
Economies with few fossil fuel reserves will have more affordability issues in 2035 as theywill need to resort to more capital-intensive power generation technologies (such as renewables) orto importing fuel forconventionalgeneration.SouthAsia,CentralAsia,andSoutheastAsiahavetheworstaffordabilityandmayneedadditionaltariffsupport(forinstancethroughlifelinetariffs)toensureinclusiveness.AffordabilityinEastAsia,however,willimprovesubstantially.In2035,therewillstillbeagapinaffordabilitybetweendevelopedanddevelopingAsia;butitwilldiminishwithrespectto2010.TheBAUscenarioassumesasmallpenetrationofrenewables;furtherincreasesintherenewablesharearelikelytoworsenaffordability.
D. Regional Cooperation
Regionalcooperationcangenerally increaseenergysecurity(self-sufficiencyanddiversification)andaffordability.Thekeytosuccessful integrationmaybeseekingwin–winsituationswherebyanenergysuppliercollectsbenefitsinadditiontomonetarycompensation.Someexamplesaretheexchangeofenergyforenergyexpertise(e.g.,inrenewablesorcleancoalinthecaseofKazakhstan);ofenergyfordiversity(andhenceresilience);ortheenergy–waterexchangeinCentralAsia.
Forpowersystems,thebestopportunitiesfor integrationareinCentralAsiawherearegionalpower system would be more diversified than any single national system because their individuallydominantpowergenerationtechnologiesarecomplementary.InSoutheastAsia,Cambodia,Indonesia,the Lao PDR, Myanmar, Singapore, and Viet Nam could increase the diversification of their powersystemsthroughregionalintegration.BhutanandNepalwouldgreatlybenefitfromintegrationinSouthAsia.
