Isikali esikhulu sokugcinwa kwebhetri sinokuhlangabezana neemfuno zomthwalo omkhulu, kodwa ukusebenza kwawo kuxhomekeke kubude bexesha kunye nohlobo lomthwalo obandakanyekayo. Uninzi lwegridi-yesikali senkqubo yebhetri efakwe namhlanje inokukhupha umthamo ogcweleyo kangangeeyure ezi-2 ukuya kwezi-4, izenza zisebenze kakhulu kwincopho yemihla ngemihla yokutsheva kunye nolawulo lwamaxesha amaninzi, kodwa ayifanelekanga kangako{4}}kumandla okugcinwa kweentsuku ezininzi.
Umahluko ubalulekile kuba "umthwalo wokuphatha" ubandakanya iinkonzo zegridi ezahlukeneyo. Ubude bexesha-leemfuno ezifana nokuzinzisa amaxesha amaninzi xa umzi-mveliso uhamba ngaphandle kweintanethi, ugcino olukhulu lwebhetri luyagqwesa -ukuphendula ngeemilliseconds xa kuthelekiswa nemizuzu emininzi efunwa ziincanca zerhasi eziqhelekileyo. Ukutshintsha imveliso yelanga ukusuka emini emaqanda ukuya kwimfuno ephezulu yangokuhlwa, umgangatho weeyure ezi-4 usebenza kakuhle kwiimarike ezininzi. Kodwa ukucima okongeziweyo okanye ukugcinwa kwamaxesha onyaka, itekhnoloji yebhetri yangoku ijongene nemiqobo yezoqoqosho kunye nezobugcisa.
Okwenyani-uMsebenzi wokuPhathwa koMlayisho weHlabathi
Amanani asuka ku-2024 abonisa ukuba ukugcinwa kwebhetri okukhulu kangakanani na ukubunjwa kwakhona kwegridi yokusebenza. Umsebenzisi wegridi waseCalifornia (CAISO) ubone iibhetri zibonelela ngaphezulu kwe-21% yemfuno yenkqubo iyonke ngexesha lasemva{3}}ixesha lobushushu bexesha ngo-Okthobha 7, 2024, likhupha i-8,354 MW kwindawo ephezulu. Ngeeyure eziqhelekileyo zokukhupha, iibhetri ngoku zihlala zihlangabezana ne-13% yemfuno yombane ye-CAISO, kunye nemirhumo yeyure ephezulu ifikelela kuma-26%{11}}ipesenti ezili-10 zokwanda kwepesenti kwiinyanga nje ezili-12.
Ezi ayingobuchule bethiyori. Xa iHornsdale Power Reserve yaseMazantsi eOstreliya yafumanisa ukusilela kumatshini wombane oyi-560 MW ngoDisemba ka-2017, ibhetri yafaka i-7.3 MW kwigridi kwiimilliseconds, ukuzinzisa amaza phambi kokuba iinkqubo zogcino zesiqhelo ziphendule. Eli ziko, ekuqaleni laliyi-100 MW/129 MWh laze kamva landiswa laya kutsho kwi-150 MW/194 MWh, laphatha ama-55% eenkonzo zolawulo lwamaxesha okwenziwa koMzantsi Australia kwiinyanga ezintandathu zokuqala zokusebenza.
I-Texas yongeze i-4 GW yomthamo webhetri ngo-2024 kuphela, inceda urhulumente ukuba aphephe iingxaki ezithembekileyo zasehlotyeni ebeziyithwaxa iminyaka edlulileyo. Amaxabiso ombane ngo-Agasti 2024 abekwi-avareji ye-$160 ngemegawathi nganye-ngeyure engaphantsi kuno-Agasti ka-2023, ngokuyinxenye abalelwa kwiibhetri ezigudisayo iincopho zemfuno. Ibali liyaphinda kwiimakethi: ugcino lwebhetri enkulu luthintela into ebikade ingenakuthinteleka{8}}ingxakeko yezityalo ezixabisa kakhulu ngexesha lemozulu embi.
Isinyanzelo seyure-esine kunye nokuba ithetha ukuthini
Uninzi lwezinto eziluncedo -iibhetri ezifakelwe ngo-2024 zenzelwe 4-iyure yeyure xa zikhutshwa ngokupheleleyo. Oku akufuneki. Ubunjineli busukela kwi-lithium - kwiimpawu zebhetri yeion-ukutshaja ngokukhawuleza kunye nokukhupha ngaphezu kweeyure ze-4 kukhawulezisa ukuthotywa kwaye kunokuphelisa iziqinisekiso. Uqoqosho lubonisa imithetho yemarike: Inkqubo yokwanela kwezixhobo zaseCalifornia, umzekelo, ifuna iiyure ezi-4 zemveliso ezinzileyo ukuze iibhetri zifumane ikhredithi yomthamo opheleleyo.
Olu bude bulawula ilanga lemihla -ukuya{1}}ishifti yangokuhlwa ngokufanelekileyo. Iibhetri ze-CAISO zihlawulisa ngexesha lasemini xa izikhukhula zelanga zikhukula igridi kunye namaxabiso ehla (kaninzi ngaphantsi kwe-$ 50 / MWh), emva koko ikhuphe ukusuka kwi-5 PM ukuya kwi-9 PM xa imfuno iphezulu kunye nokucima kwelanga. Ukutshaja kwebhetri ngoku kumele i-14.7% yomthwalo we-CAISO ngeeyure ze-10-13, ifunxa oko bekuya kucuthwa ukuveliswa okuhlaziyekayo.
Unyino lubonakala xa imfuno idlula ixesha elide. Ilanga -lobushushu beentsuku ezininzi zidityaniswe nesizukulwana somoya ophantsi, okanye ukucinywa kwentambo enkulu yothumelo lweentsuku ezingapheliyo, kutyhala ngaphaya koko iibhetri zeeyure ezi-4 zinokuzigcina. Njengoko omnye umqhubi wegridi ephawulwe kwingxelo yebhetri yaseCalifornia yowama-2024, i-horizons elinganiselweyo kwisoftware yentengiso ngamanye amaxesha ibangela ukuba iibhetri ziphume kwangoko xa amaxabiso enyuka ngokungalindelekanga, ebashiya bephele kancinci xa imfuno yokwenyani ifika kwiiyure kamva.
Uphononongo lwe-NREL's Storage Futures lufumanise ukuba iisistim ezingaphantsi kwe-40% ezinokuthi zihlaziyeke zifuna kuphela-ukugcinwa kwexesha elifutshane. Kwi-80% evuselelekayo, ugcino oluphakathi-lobude (4{8}}iiyure ezili-16) luba yimfuneko. Ngaphaya kwe-90%,{9}}ixesha elide logcino oluthatha iintsuku luba yimfuneko{10}}umqobo welithium{11}}yoqoqosho lwe-ion kuyasokola ukuhlangabezana neendleko ezifanelekileyo.
Iindlela eziNtathu zokuSebenza: Isakhelo sokuQonda iSakhono
Isikali esikhulu sokugcinwa kwebhetri sisebenzisa igridi kuzo zonke izikali zexesha ezithathu ezahlukeneyo, nganye ineempawu zokuphatha umthwalo:
Impendulo yangoko (Imizuzwana ukuya kwiMizuzu)
Iibhetri zibonelela ngolawulo lwamaxesha amaninzi kunye nogcino lokujikeleza{0}}ukugcina igridi etshintshanayo yangoku kanye ku-60 Hz (okanye 50 Hz kweminye imimandla). Xa i-frequency frequency yehla ngaphantsi kwe-49.8 Hz, njengoko yenzayo ngexesha lesiganeko saseLoy Yang e-Australia, iibhetri ziphendula ngaphakathi kwe-150 millisecond. Esi santya asinakwenzeka ngokwasemzimbeni kwiijenereyitha ezishushu ezifuna ukusonta iiinjini zomoya.
Iibhetri zaseCarlifonia zibonelele ngobuninzi bomthamo wolawulo ngexesha lexesha eliphakamileyo lelanga ngo-2024, xa ukuguquguquka okukhawulezileyo okuvela kumafu adlulayo kunokuwenza umbane. Esi sicelo sisebenzisa iqhezu lomthamo webhetri kodwa siyalela amaxabiso eprimiyamu kuba ukuthembeka kubaluleke ngaphezu komthamo wamandla.
Ukukhwela ibhayisekile yonke imihla (iiyure)
Amandla arbitrage{0}}ukutshaja xa umbane ungabizi kakhulu kwaye ukhutshwa xa kubiza{1}}ukuqhuba uninzi lofakelo lweebhetri. Kwiinkqubo ezinokungena okuphezulu kwelanga, oku kuthetha ukuba intlawulo enye-umjikelo wokukhupha ngosuku. Ixabiso livela ekuthobeni "igophe ledada," laa ndlela inyukayo yangokuhlwa xa ilanga lisihla kodwa imfuno ihlala iphezulu.
Iibhetri zaseTexas zibonise oku ngoSeptemba ka-2024 xa amaza obushushu atyhala imfuno edlula i-85 GW. Iibhetri ezikhutshwe yi-3.4 GW ngexesha leeyure eziphakamileyo, ezilingana nezixhobo ezininzi zamandla amakhulu. Ngokungafaniyo neepeaktha zerhasi ezifuna isaziso ukuze ziqalise, iibhetri zitshintsha ukusuka ekutshajisweni ukuya ekukhupheni ngoko nangoko ngokusekelwe kwimiqondiso yexesha lokwenyani{5}}.
Ugcino olwandisiweyo (Iintsuku+)
Apha kulapho igridi yangoku{0}}yeebhetri zesikali zijongana neyona miceli mngeni. Ukwenza amandla ngeveki-ixesha elide lokwenziwa ngokutsha okuphantsi kuya kufuna iibhanki ezinkulu zebhetri{3}}zibize iindleko ezinkulu kunye neendleko zokushiya umthamo ungasebenzi phantse unyaka wonke. Uhlalutyo oluvela kwi-E3 Consulting lubonise ukuba ixabiso lomthamo (ELCC) weebhetri liyancipha ngokukhawuleza xa ukungena kudlula i-40 GW eCalifornia, njengoko iibhetri zikhuphisana ngokwandayo kunezityalo ezibiza kakhulu.
Kwiindawo zokugcina eziphezulu kakhulu, ixabiso lesiphakamiso liyatshintsha. Awusatshintshi esona sizukulwana sibiza kakhulu{1}ubonelela nge-inshurensi ngokuchasene nonikezelo olunqabileyo kodwa oluyintlekele. Iimarike azikacingi ukuba zingayibuyekeza njani ngokufanelekileyo loo nkonzo.
Iipateni ezisahlumayo kunye neeTrajectories zexesha elizayo
Ulwakhiwo oluseCalifornia naseTexas lutyhila ipateni: ukugcinwa kwebhetri enkulu kuqala kuthatha indawo yemfuno yezityalo zerhasi encothulayo, emva koko ivumele ukungena okuphezulu okunokuhlaziywa, kwaye ekugqibeleni iba ngumthwalo kuyo. Ukutshaja ibhetri ngoku kubalela inxalenye elinganisekayo yemfuno yegridi-14.7% ngexesha leeyure zasemini kwi-CAISO. Lo "mthwalo" uluncedo, ufunxa oko bekuya kuncitshiswa ilanga, kodwa utshintsha ucwangciso lwegridi.
Ukongezwa komthamo kuyatshintsha ukusuka kwi-hybrid solar{0}}kunye-nogcino ukuya kugcino oluzimeleyo. Phakathi kuka-2025 kunye no-2028, umthamo ozimeleyo ocetywayo e-California udlula i-17.8 GW xa kuthelekiswa ne-7.2 GW kwiinkqubo -ezikhoyo. Iikhredithi zerhafu zotyalo-mali zoMthetho wokuNcitshiswa kwamaxabiso otyalo-mali kugcino oluzimeleyo luqhube olu tshintsho, kodwa lukwabonisa nabaqhubi abafuna ubhetyebhetye lokuhlawula kwigridi, kungekuphela nje i-solar edityanisiweyo.
Iindlela zeendleko zixhasa ixesha elide ukuba lisebenze. Amaxabiso eepakethi zebhetri ehle nge-20% ngo-2024 ukuya kwi-$115/kWh kwihlabathi jikelele. Ngala maxabiso, iiyure ezi-6 kunye neeyure ze-8 ziqala ukwenza ingqiqo yezoqoqosho kwiimeko ezithile zokusetyenziswa. Abaphuhlisi abaninzi bavavanya iinkqubo zeyure ezili-10 kunye neeyure ezili-12, nangona zisahleli ngaphandle kunomgaqo.
Iikhemistri ezizezinye zimi kwimarike ixesha elide-. Iibhetri zesodium -zeionion{4}}20-30% zitshiphu kune-lithium{7}}iionni kwisikali{8}}ukuncama amandla okuxinana ngexabiso kunye nokhuseleko. Iibhetri zomoya ze-iron{9} zithembisa ukukhutshwa kweveki yonke kodwa zihlala zithengiswa kwangaphambili. Iibhetri zokuhamba kwe-Vanadium redox zilinganisa umthamo wamandla ngokuzimeleyo kumthamo wamandla, zibenza zibe ngcono ngokwethiyori ixesha elide, kodwa zibambe ngaphantsi kwe-1% yemarike ngenxa yeendleko eziphezulu zangaphambili.
Imida Eluncedo Kufuneka Uyazi
Iingqwalasela zokhuseleko zinyanzelisa ukuba ugcino lwebhetri lubekwe phi kwaye likhulu kangakanani. Umlilo kaJanuwari 2025 weMoss Landing eCalifornia unyanzelise ukuba kuphume abantu abayi-1,500 kwaye yaphinda yabangela inkxalabo yoluntu malunga nokubaleka kobushushu kwiinkqubo ze-lithium{4}}. Amagunya aliqela, kuquka iindawo zaseNew York, amisele ukumiswa kweeprojekthi zebhetri ezintsha ngelixa iikhowudi zomlilo ezihlaziyiweyo ziphuhliswa.
Ufakelo lwangoku lusebenzisa uyilo lwesikhongozeli esinemodyuli ezineemfuno zesithuba ukuthintela ukusasazeka komlilo, kodwa iiprojekthi ezindala azinazo ezi zikhuselo. Umyinge wokucinywa kweshishini ngo-2024 wawuyi-5.8% ye-nameplate umthamo kwi-CAISO{3}}iibhetri ezingafumanekiyo ngenxa yogcino, iziphene, okanye iinkxalabo zokhuseleko xa igridi yayizifuna kakhulu.
Izithintelo zezinto eziphathekayo ziphakamisa-umbuzo wexesha elide. Ubonelelo lweLithium luyanda nge-12% ngonyaka ukuya kutsho ngo-2030 ngokutsho kweGoldman Sachs, kodwa olo kukhula kufuneka luhambelane nemfuno ekhulayo evela kwii-EV zombini kunye nokugcinwa okumileyo. Ukufumana i-Cobalt evela kwi-Democratic Republic of Congo kuphakamisa imiba yeenqobo ezisesikweni kunye nokubonelela ngenkxaso. Uninzi lwabavelisi baye batshintshela kwi-lithium iron phosphate (LFP) chemistry, ephelisa i-cobalt kodwa inika amandla aphantsi kancinci.
Uxinzelelo lwengeniso kwiimalike ezisele zikhulile luhlengahlengisa uqoqosho lweprojekthi. Umndilili wengeniso yemalike kwi-CAISO wehle nge-35% ngo-2024 ukuya malunga ne-51,000 yeedola ze-MW{5} ngonyaka njengoko umthamo webhetri ukhule ngokukhawuleza kunerenti yokunqongophala. Iibhetri zakwangoko zithathe amaxabiso epremiyamu ngokuba ngabahambisi bokuqala kwiimarike zenkonzo ezincedisayo ezinengeniso. Njengoko iibhetri ezininzi zingena, ezo marike zigcwala, kunyanzelwa ukuba iibhetri zikhuphisane -kumlinganiselo ophantsi wamandla.
Iiprojekthi ezinenzuzo zixhomekeke ngakumbi kwindawo. Iibhetri ezisemva kweendawo zothumelo ezixineneyo, apho kunqongophele khona imveliso yasekhaya, iyalela iintlawulo zanyanga le. Ibhetri kwindawo ezinoguquguquko olugqithisileyo{2}njengemarike yaseTexas engamiselwanga{3}}zinokufumana iindleko zenkunzi ngokukhawuleza. Iibhetri zeGeneric kwiindawo eziphantsi{5}}ezinoguquguquko lweemarike ziyasokola ukuthethelela iindleko zazo zokwakha naxa amaxabiso ehardware ehlayo.
Oku kuthetha ntoni kuNtembeko lweGridi
Isikali esikhulu sokugcinwa kwebhetri siwele umda ukusuka kwinto entsha ukuya kwimfuneko -ezinokuhlaziywa kwakhona kwiigridi. I-California ne-Texas-ezithe xa zidibene zibalelwa kwi-61% yofakelo lweebhetri zase-US ngo-2024-azisanamava okuthembakala ehlotyeni okwakusenzeka kwiminyaka emithathu edlulileyo. Oku akuyontelekelelo; ilinganiswa ngokucima okuthintelweyo kunye namaxabiso aphantsi ngexesha ebekufanele ukuba liziganeko zoxinzelelo lwegridi.
I-US yongeze i-12.3 GW yomthamo webhetri ngo-2024, izise umthamo ofakiweyo udlule kwi-30 GW xa iquka ngasemva{5}}{6}}nezixokelelwano zeemitha. Uqikelelo lubiza i-81 GW yofakelo olongezelelweyo ukusuka ngo-2025 ukuya ku-2029. Ngelo xesha, iibhetri ziya kuba ziziseko ezingundoqo ezibalulekileyo, kungekhona ezongezelelweyo.
Kodwa "umthwalo wokuphatha" uhlala uxhomekeke-kumxholo. Kwixesha elizayo langoku-iminyaka emi-5{4}}eli-10{8}}enkulu yokugcina ibhetri iyagqwesa kwibhayisekile yemihla ngemihla kunye nokusabela ngokukhawuleza. Baza kwenza iigridi zifikelele kuma-60{9}}70% ekungeneni okuhlaziyekayo ngokuthembekileyo. Ngaphaya kwalo mda, uqala ukufuna izisombululo iibhetri ezingenakubonelelwa ngazo ngokwezoqoqosho: ugcino lwexesha lonyaka, ugcino lweeveki ezininzi, okanye iindlela zogcino lwexesha elide ezingekabikho kwinqanaba lezorhwebo okwangoku.
Utshintsho lwenzeka ngokukhawuleza kunokuba uninzi luqikelelwe. Xa ibhetri ye-Hornsdale yaya kwi-intanethi ngo-2017, abantu abathandabuzayo bayibiza ngokuba yi-PR stunt. Kwiminyaka esixhenxe emva koko, iibhetri zanikezela ngaphezulu kwesihlanu semfuno yencopho kwisihlanu -uqoqosho olukhulu kwihlabathi ngexesha lobushushu. Ayingomqobo lowo -ziziseko ezingundoqo.
Imiba engundoqo yoMsebenzi
Izinto ezininzi eziguquguqukayo zimisela ukuba isikali esikhulu sogcino lwebhetri sinokuwuphatha na umthwalo kumxholo othile:
Ixesha lomdlalo: Ukuba ixesha lakho lemfuno ephezulu lithatha iiyure ezi-3 yonke imihla, iibhetri zeeyure ezi-4 zisebenza ngokugqibeleleyo. Ukuba ujongene nencopho yeeyure ezisi-8 ebusuku xa ilanga libuthathaka, udinga ixesha elide okanye wamkele ukhuseleko oluyinxenye.
Ukukhupha ubunzulu: Iibhetri ezibekwe kwi-100 MW ziyakwazi ukugcina loo mveliso, kodwa kuphela ngexesha elilinganisiweyo. Ibhetri ye-100 MW / 400 MWh ihambisa i-100 MW ngeeyure ezi-4, okanye i-50 MW ngeeyure ezi-8, kodwa hayi i-100 MW kwiiyure ezi-8.
ULawulo lweSimo soLawulo: Okwenyani-ukusebenza kwehlabathi kufuna ukugcina iibhetri zihlawulwe inxenye ukuphendula kwiziganeko ebezingalindelekanga. Ibhetri etshajiswe ngokupheleleyo ngexesha lasemini ngexabiso eliphantsi lesola lingakhupha i-30% ngexesha lokwenyuka kwexabiso lasemva kwemini, ishiya kuphela i-70% yencopho yangokuhlwa-ukunciphisa umthamo osebenzayo xa kuthelekiswa nemilinganiselo ye-nameplate.
Ubomi bomjikelo: Iziqinisekiso zebhetri ziqinisekisa i-4,000 ukuya kwi-6,000 imijikelo phambi kokuba umthamo wehle ukuya kwi-80% yeyoqobo. Ukuba ujikeleza yonke imihla, yi-11-16 iminyaka yokusebenza. Ukukhutshwa okunzulu okanye ukukhwela ibhayisekile rhoqo kukhawulezisa ukuthotywa.
Uvakalelo lobushushu: Ubushushu obugqithisileyo kunye nokubanda kunciphisa zombini umthamo okhoyo kunye nobomi bomjikelezo. Iibhetri e-Arizona zifuna ulawulo olushushu ngakumbi kunezo zikwimozulu epholileyo, ukongeza kwiindleko zokusebenza.
Ukuqonda okubalulekileyo kukuba ukuphathwa komthwalo webhetri akuyonto yokubini. Ayingo"bangakwazi" okanye "abanakukwazi"{1}}kukuthi "phantsi kweziphi iimeko kwaye ixesha elingakanani." Impendulo iya isanda yile: ewe, kwiindidi zolawulo lomthwalo uninzi lwegridi lufuna ixesha elininzi.
Imibuzo ebuzwa qho
Ingaba igridi{0}}ikwazi ukulinganisa ixesha elingakanani iibhetri zithwele amandla?
Uninzi lweenkqubo zogcino lwebhetri ezifakwe ngo-2024 zinokukhutshwa ngamandla alinganiswe ngokupheleleyo kangangeeyure ezi-2 ukuya kwezi-4. Ibhetri ye-100 MWh ene-400 MWh umthamo ingazisa i-100 MW ngokuqhubekayo kwiiyure ezi-4 phambi kokuphelelwa. Nangona kunjalo, abasebenzi abafane bazikhuphe ngokupheleleyo iibhetri xa beziqhelisa{9}bagcina imida ebekelwe bucala ukuphendula kwiziganeko ezingalindelekanga zegridi. Okwenyani{11}ukukhutshwa kwehlabathi ngokuqhelekileyo ukusuka kwi-60-80% yomthamo wethiyori.
Kwenzeka ntoni xa ugcino lwebhetri luphela ngexesha lemfuno ephezulu?
Abasebenzisi begridi balawula imeko yebhetri{0}}yo{1}}yentlawulo ukunqanda ukuphela kokuphela ngexesha leeyure ezimandundu. Kwimisebenzi yaseCalifornia ka-2024, isoftwe yentengiso iphucula ukuhanjiswa kwebhetri imini yonke, itshaja ngexabiso eliphantsi{4}}leyure zelanga kwaye igcina ukukhutshelwa ngamaxesha aziwayo. Ukuba imfuno idlula uqikelelo, abaqhubi banokubiza iijenereyitha zemveli njenge-backup. Umngcipheko ayizizo iibhetri ezisike ngokukhawuleza{7}kukuba iibhetri ezifika ngeeyure eziphakamileyo ziphele kancinci ngenxa yokuba ziphume kwangethuba xa amaxabiso enyuke ngokungalindelekanga.
Ngaba iibhetri zinokuthatha indawo yezityalo zerhasi yendalo ngokupheleleyo?
Ukutsheva okuphakamileyo kwemihla ngemihla kunye nokuphendula ngokukhawuleza, ugcino olukhulu lwebhetri sele luthatha indawo yemfuno yeencopho ezintsha zerhasi kwiimarike ezininzi. I-Texas kunye neCalifornia zavuma izityalo ezimbalwa zegesi ezitsha ngo-2024 ngaphandle kokukhula komthwalo omkhulu, kuxhomekeke kufakelo lwebhetri. Nangona kunjalo, ukutshintshwa okupheleleyo kujongene nemida. Iiplanti zegesi zinokuqhuba ngokuqhubekayo kangangeentsuku xa zifuneka, ngelixa iibhetri zeyure ezi-4{6} zingenako. Kude kube ixesha elide lokugcina ixesha lisebenza ngokwezoqoqosho, uninzi lweegridi ziya kugcina isizukulwana esishushu esinokuhanjiswa njenge-inshurensi ngokuchasene nokusilela okwandisiweyo.
Kutheni bengakhe nje iibhetri ezinkulu ixesha elide?
Ubunzima bexesha loqoqosho. Iyure nganye eyongezelelweyo yokugcina umthamo wongeza iindleko ezibalulekileyo-malunga ne-$150{3}}200/kWh yebhetri ngokwayo kunye nebhalansi{4}}yeendleko zesixokelelwano. Ibhetri yeeyure ezi-8 ixabisa phantse kabini ibhetri yeeyure ezi-4 zemveliso yamandla efanayo. Nangona kunjalo ibhetri yeeyure ezisi-8 yenza kuphela ingeniso ngexesha leziganeko ezinqabileyo xa amaxabiso ehlala ephezulu ixesha elide. Uninzi lweebhetri lubuyisela utyalo-mali lwazo ngomjikelo omnye wemihla ngemihla, nto leyo eyenza ukuba iindleko ezongezelelweyo zexesha elide kube nzima ukuzithethelela kulwakhiwo lwemarike lwangoku.
