The New Electricity Law provides a legal environment for grid-connected power generation of new energy

Release time: 2012-04--25
Recently,accordingtoWuJiandong,vicechairmanoftheChinaIntelligentEngineeringResearchAssociation,attheRenewableEnergyPowerGenerationandGridGridForum,thepowerlawthatisbeingrevisedwillincludetherelevantcontentofnewenergygrid-connectedpowergeneration,whichwillprovidelawsfornewenergygrid-connectedpowergenerationsurroundings.Sincemycountry'scurrent"ElectricPowerLawofthePeople'sRepublicofChina"wasimplementedonApril1,1996,thedevelopmentenvironmentoftheelectricpowerindustryhasundergonegreatchanges,andthecurrentelectricpowerlawhasobviouslylaggedbehindthedevelopmentneedsoftheelectricpowerindustryinsomeaspects.Forexample,theproblemsrelatedtogrid-connectedpowergenerationofnewenergy.Inrecentyears,especiallysincethe11thFive-YearPlan,thedevelopmentofnewenergyhasbeenveryrapid,buttheconstructionofsupportinglawsandpolicieshasbeenrelativelylagging.Manyobstaclestothe"bottleneck".Creatingalegalenvironmentsuitableforthedevelopmentofnewenergymayprovideastrongguaranteeforthelarge-scaleandrapiddevelopmentofnewenergy,anditisexpectedtosolvetheolddifficultproblemofthepowergrid.   Thedevelopmentofnewenergyisrestrictedbytheconstructionofthepowergrid  AccordingtoSunYucai,SecretaryofthePartyLeadershipGroupandExecutiveViceChairmanofthemycountryElectricityCouncil,intermsofthepowerstructureofChinalastyear,theproportionofcleanenergysuchashydropower,nuclearpower,windpower,andsolarpowerreached27.5%,anincreaseof0.9%overthepreviousyear.Thegrid-connectedcapacityofwindpowerandsolarpowerhasincreasedextremelyrapidly.Lastyear,thegrid-connectedcapacityofwindpowerwas45.05millionkilowatts,andthegrid-connectedcapacityofsolarpowerreached2.14millionkilowatts,anincreaseof52%and723%respectivelyoverthepreviousyear.Intermsofpowergrids,theabilitytoabsorbwindandsolarpowergenerationandtheabilitytosafelydispatchhasnotbeenimprovedaccordingly,whichhascausedthecontradictionthatmanynewenergysources"cannotbeabsorbed".Accordingtorelevantdata,mycountry’swindpowercurtailmentlastyearexceeded1.1billionkWh,accountingfor12%ofthetotalwindpowergeneration.In2008,thewindpowercurtailmentwasonly296millionkWh.Thisshowsthatthelarge-scalecentralizeddevelopmentofwindpowerisincreasing.Themoreseverelyitisaffectedbytheconstructionofpowergridtransmissionchannels.Someexpertspointedoutthatlarge-scale"bundled"transmissionandon-sitebalancedconsumptiondidnoteffectivelysolvetheproblemofgridconnectionofwindpowerbases,resultinginadisguisedwasteofresources.Thisisincontrasttothelaggingofgridplanningandconstructionandlackofsupportingfacilities.Adaptedlaws,policiesandstandardsarecloselyrelated.Itisunderstoodthatthe"RenewableEnergyLaw"stipulatesthatgridcompaniesshall,inaccordancewiththeplanningandconstructionofrenewableenergydevelopmentandutilization,fullypurchasetheon-gridpowerofrenewableenergygrid-connectedpowergenerationprojectsthatmeetthegrid-connectedtechnicalstandardswithintheirgridcoverage.Itisproposedthatgridcompaniesshouldimprovegridoperationmanagementandincreasetheabilitytoabsorbrenewableenergypower.Intermsofwindpowergridconnection,thenationalstandardGB/T19963-2011"TechnicalRegulationsforWindFarmAccesstoPowerSystems"waspromulgatedattheendoflastyearandwillbeimplementedonJune1thisyear.Itisinlinewiththeindustrystandard"LargeWindFarms"approvedbytheNationalEnergyAdministration.Grid-connecteddesigntechnicalspecificationsjointlystipulatetherelevanttechnicalrequirementsforgrid-connectedwindfarms.AnalysisbelievesthattherehavebeenmanywindabandonmentsinInnerMongolia,Jilinandotherregionsbecausetherelationshipbetweenwindfarmsandpowergridsisnotregulatedbyrelevantindustrystandardsandnationalstandards.However,whetherrenewableenergycanbefullyintegratedintothegridwithinthe“gridcoveragearea”alsodependsonthepaceofconstructionofthegridtransmissionchannel.   Theformulationofregulationsandstandardsshouldbe"appropriatelyadvanced"  AccordingtorelevantdatafromthemycountryElectricityCouncil,China’swindpowerinstalledcapacityisplannedtobe100millionkilowattsand180millionkilowattsin2015and2020,respectively,andtheplannedsolarpowerinstalledcapacityis5millionkilowattsin2015and25millionkilowattsin2020.Atpresent,theabovedatamaystillbeconservative.Duetotheincentivesofthenationalsolarphotovoltaicpowergenerationtariffpolicy,thedevelopmentspeedofsolarphotovoltaicpowergenerationinmycountryislikelytoacceleratefurther,especiallyintheBIPVfield,whichwillexceedexpectations.Ontheotherhand,thedevelopmentthinkingofwindpowerhasalsochangedfromlarge-scalecentralizeddevelopmenttolarge,mediumandsmall,decentralizedandcentralized,landandseajointdevelopment.Undertheguidanceofappropriatepolicies,smallandmedium-sizedwindfarmswillbeconnectedtothegridandconsumedlocally.Itisalsoexpectedtogainextensivedevelopment.
