Isitoreji sebhethri sesikali esikhulu singabhekana nezidingo zomthwalo omkhulu, kodwa ukusebenza kahle kwaso kuncike ubude besikhathi kanye nohlobo lomthwalo ohilelekile. Amasistimu amaningi webhethri-esikali segridi afakwe namuhla angaphuma ngomthamo ogcwele amahora angu-2 kuya kwangu-4, okuwenza asebenze kahle kakhulu ekushefinini okuphezulu kwansuku zonke nokulawulwa kobuningi, kodwa awafaneleki kangako amandla{4}esipele wezinsuku eziningi.
Umehluko ubalulekile ngoba "umthwalo wokubamba" uhlanganisa amasevisi egridi ahlukene. Isikhathi esifushane-sidinga imfuneko njengokuzinzisa imvamisa lapho isikhungo samandla sihamba ngokungaxhunyiwe ku-inthanethi, isitoreji sebhethri esikhulu siyadlula{2}}ukuphendula ngama-millisecond uma kuqhathaniswa namaminithi ambalwa adingwa amapekha avamile egesi. Ukushintsha ukukhiqizwa kwesola kusuka emini enkulu kuya ekufuneni okuphezulu kwakusihlwa, izinga lamahora angu-4 lisebenza kahle ezimakethe eziningi. Kodwa ngokucisha okunwetshiwe noma isitoreji sesizini, ubuchwepheshe bamanje bebhethri bubhekene nezinkinga zomnotho nezobuchwepheshe.
Ukusebenza Kwangempela Kokusingathwa Komthwalo Womhlaba{{0}
Izinombolo ezisuka ku-2024 zibonisa ukuthi isitoreji sebhethri esikhulu kangakanani sibumba kabusha ukusebenza kwegridi. I-opharetha yegridi yase-California (CAISO) ibone amabhethri ehlinzeka ngaphezu kuka-21% wengqikithi yesidingo sesistimu phakathi nesikhathi-sesizini se-heatwave yakamuva ngo-Okthoba 7, 2024, ekhipha u-8,354 MW phezulu. Ngamahora ajwayelekile okukhipha, amabhethri manje ahlangabezana ngokuqhubekayo no-13% wesidingo sikagesi se-CAISO, kanti iminikelo yehora eliphakeme ifinyelela ku-26%-iphuzu elikhuphukayo elingamaphesenti angu-10 ezinyangeni eziyi-12 kuphela.
Lawa akuwona amakhono etiyetha. Lapho i-Hornsdale Power Reserve eNingizimu ne-Australia ithola ukwehluleka kwesikhungo sikagesi esingu-560 MW ngoZibandlela wezi-2017, ibhethri yajova u-7.3 MW kugridi ngama-millisecond, yazinza imvamisa ngaphambi kokuba izinhlelo zokusekelayo ezivamile ziphendule. Lesi sikhungo, ekuqaleni sasingu-100 MW/129 MWh futhi kamuva sanwetshwa safinyelela ku-150 MW/194 MWh, sasingatha u-55% wezinsizakalo zokulawula imvamisa zaseNingizimu Australia ezinyangeni zaso zokuqala eziyisithupha zokusebenza.
I-Texas yengeze i-4 GW yomthamo webhethri ngo-2024 kuphela, isiza izwe ukuthi ligweme izingqinamba zokwethenjelwa ehlobo ebezilikhungethe eminyakeni edlule. Izintengo zamandla ngo-Agasti 2024 zaba nesilinganiso esingu-$160 nge-megawatt ngayinye-ngehora ngaphansi kuka-Agasti 2023, ngokuyingxenye ngenxa yokushelela kwamabhethri ukuphakama kwezinga eliphezulu. Indaba iyaphinda ezimakethe zonke: ukugcinwa kwebhethri kwesilinganiso esikhulu kuvimbela lokho obekungagwemeki{8}}ingxabano enzima yezitshalo ezihamba phambili ezibizayo ngesikhathi sezulu esibi kakhulu.
Umkhawulo-Wamahora Amane nokuthi Kusho Ukuthini
Amabhethri amaningi esikali-esikali afakwe kuze kube u-2024 ayedizayinelwe isikhathi esingamahora angu-4-lapho ekhishwa ngokugcwele. Lokhu akunasizathu. Ubunjiniyela busukela ezicini zebhethri ye-lithium-ion-ukushaja okusheshayo nokushajwa kunamahora angu-4 kusheshisa ukuwohloka futhi kungaqeda iziqinisekiso. Ezomnotho zibonisa imithetho yemakethe: Uhlelo lwase-California lokwanela kwezinsiza, ngokwesibonelo, ludinga okukhiphayo okusimeme kwamahora ama-4 ukuze amabhethri athole ikhredithi yomthamo ogcwele.
Lobu bude besikhathi busingatha ngempumelelo i-solar yansuku zonke-kuya{1}}yakusihlwa. Amabhethri e-CAISO ashaja phakathi nemini lapho i-solar ikhukhula igridi nezintengo zehla (ngokuvamile ngaphansi kuka-$50/MWh), bese aphuma ngo-5 PM kuya ku-9 PM lapho isidingo siphakama kanye nokufiphala kwelanga. Ukushajwa kwebhethri manje sekumele u-14.7% womthwalo we-CAISO phakathi namahora 10-13, okudonsa lokho obekungancishiswa ukukhiqiza okuvuselelekayo.
Umkhawulo uvela lapho isidingo sidlula ukunikezwa isikhathi eside. -Igagasi lokushisa lezinsuku eziningi elihlanganiswe nokuphehla komoya omncane, noma ukuphela kolayini wokudlulisela phambili izinsuku ezihlala njalo, kudlulela ngale kwalokho amabhethri angasebenza amahora angu-4. Njengoba omunye u-opharetha wegridi ephawulile embikweni webhethri wase-California wango-2024, ama-horizons okuthuthukisa okulinganiselwe kusofthiwe yemakethe kwesinye isikhathi abangela ukuthi amabhethri aphume kusenesikhathi lapho amanani enyuka ngokungalindelekile, okuwashiya encipha kancane lapho isidingo esikhulu sangempela sifika emahoreni kamuva.
I-NREL's Storage Futures Study ithole ukuthi amasistimu anokuvuselelwa okuguquguqukayo okungaphansi kuka-40% adinga kuphela-isitoreji sesikhathi esifushane. Ekuvuseleleni okungu-80%, isitoreji{4}}sesikhathi esimaphakathi (4-amahora angu-16) siba sibalulekile. Ngalé kuka-90%,{9}}ubude bezinsuku zesitoreji esithatha isikhathi eside budingeka{10}}umzabalazo wamanje we-lithium{11}}wezomnotho we-ion ukuze uhlangabezane ngendlela engabizi kakhulu.
Izindlela Zokusebenza Ezintathu: Uhlaka Lokuqonda Ikhono
Isitoreji sebhethri sesikali esikhulu sinikezela ngegridi ezikalini ezintathu ezihlukene zesikhathi, ngasinye esinezici ezihlukile zokuphatha umthwalo:
Impendulo Esheshayo (Amasekhondi kuya Emaminithini)
Amabhethri ahlinzeka ngokulawula imvamisa kanye nokugodla kokuphotha{0}}ukugcina ukushintshana kwamandla wegridi ngokunembile ku-60 Hz (noma u-50 Hz kwezinye izifunda). Uma imvamisa yesistimu yehla ngaphansi kuka-49.8 Hz, njengoba yenza ngesikhathi sesigameko se-Loy Yang e-Australia, amabhethri aphendula phakathi kwama-millisecond angu-150. Lesi sivinini asikwazi ngokoqobo kumajeneretha ashisayo adinga ukuphotha ama-turbines.
Amabhethri ase-California ahlinzeke ngomthamo omningi wokulawula ngesikhathi samahora ashisa kakhulu elanga ngo-2024, lapho ukushintshashintsha okusheshayo okuvela emafwini adlulayo bekuzophazamisa ugesi. Lolu hlelo lokusebenza lusebenzisa ingxenye encane yomthamo webhethri kodwa luyala izintengo zeprimiyamu ngoba ukwethembeka kubaluleke ngaphezu kwevolumu yamandla.
Ukuhamba Ngebhayisikili Nsuku Zonke (Amahora)
I-Energy arbitrage-ukushaja uma ugesi ushibhile futhi ukhipha uma ubiza{1}}kudonsa ukufakwa kwamabhethri amaningi. Kumasistimu anokukhanya kwelanga okuphezulu, lokhu ngokuvamile kusho umjikelezo wokushaja owodwa-owodwa ngosuku. Inani livela ekwenzeni isicaba "ijika ledada," leyo rempu yakusihlwa ewummango lapho ilanga lehla kodwa isidingo sihlala siphezulu.
Amabhethri aseTexas akhombise lokhu ngoSepthemba 2024 lapho igagasi lokushisa licindezela ukudlula i-85 GW. Amabhethri alahlwe ngu-3.4 GW phakathi namahora aphakeme, okulingana nezimboni zamandla eziningana ezinkulu. Ngokungafani neziqongo zegesi ezidinga isaziso ukuze ziqale, amabhethri ashintsha ukusuka ekushajeni ukuya ekushajeni ngokushesha ngokusekelwe{5}}kumasiginali entengo yesikhathi sangempela.
Isipele Esinwetshiwe (Izinsuku+)
Yilapho amabhethri esikali segridi-ebhekana khona nezinselele ezinkulu. Ukunika amandla isonto-isikhathi eside sokukhiqiza okuphansi okungavuselelekayo kuzodinga amabhange amakhulu{3}}abize kokubili ezindlekweni zekhephithali kanye nezindleko zamathuba okushiya umthamo ungasebenzi isikhathi esiningi sonyaka. Ukuhlaziywa okuvela ku-E3 Consulting kubonise ukuthi inani lamandla (i-ELCC) lamabhethri lehla kakhulu uma ukungena sekungaphezu kuka-40 GW e-California, njengoba amabhethri aya ngokuya eqhudelana namanye kunezitshalo eziphezulu ezibizayo.
Ekungeneni okuphezulu kakhulu kwesitoreji, isiphakamiso senani siyashintsha. Awusafaki esikhundleni isizukulwane esibiza kakhulu{1}uhlinzeka ngomshwalense ngokumelene nokushoda kwezinto ezingavamile kodwa eziyinhlekelele. Izimakethe azikacabangi ukuthi zingayinxephezela kanjani ngokwanele leyo sevisi.
Amaphethini Asafufusa kanye Nendlela Yekusasa
Ukwakhiwa eCalifornia nase-Texas kuveza iphethini: isitoreji sebhethri esikhulu kuqala singena esikhundleni sesidingo sezitshalo ezintsha zokubeka igesi, bese sivumela ukungena okuphezulu okuvuselelekayo, futhi ekugcineni kube umthwalo kuwo ngokwawo. Ukushajwa kwebhethri manje kubalela ingxenye elinganisekayo yesidingo segridi-14.7% phakathi namahora asemini ku-CAISO. Lo "mthwalo" uyazuzisa, udonsa lokho obekungancishiswa ngelanga, kodwa ushintsha ukuhlelwa kwegridi.
Izengezo zamandla ziyashintsha zisuka ku-hybrid solar-kanye-nesitoreji ziye kwisitoreji esizimele. Phakathi kuka-2025 no-2028, umthamo ohleliwe ozimele e-California udlula u-17.8 GW uma kuqhathaniswa no-7.2 GW kumasistimu-akhona. Amakhredithi entela otshalomali oMthetho Wokuncishiswa Kokwehla Kwamanani Emali yesitoreji esizimele ahole lolu shintsho, kodwa futhi abonisa opharetha abafuna ukuguquguquka kokukhokhisa besuka kugridi, hhayi nje i-solar ebhanqiwe.
Ama-trajectories ezindleko asekela ubude besikhathi eside ukuze busebenze. Izintengo zephekhi yebhethri zehle ngo-20% ngo-2024 zaya ku-$115/kWh emhlabeni jikelele. Kulezi zintengo, amasistimu angu-6 namahora angu-8 aqala ukwenza umqondo wezomnotho ezimweni ezithile zokusetshenziswa. Onjiniyela abaningana bahlola amasistimu obude besikhathi samahora angu-10 namahora angu-12, nakuba behlala behlukile kunomthetho.
Amanye amakhemistri ami isikhathi eside-semakethe. Amabhethri e-sodium-i-ion-20-ashibhe ngo-30% kune-lithium{7}}i-ion esikalini-adela ukuminyana kwamandla ngezindleko nokuphepha. Amabhethri e-ayoni{9}}athembisa ubude besikhathi sokuphuma kweviki lonke kodwa ahlala engathengiswanga ngaphambili. Amabhethri agelezayo e-Vanadium redox akala umthamo wamandla ngaphandle komthamo wamandla, okuwenza abe ngcono ngokwengqondo isikhathi eside, kodwa athathe ngaphansi kuka-1% wemakethe ngenxa yezindleko eziphezulu zangaphambili.
Imikhawulo Engokoqobo Okufanele Uzazi
Ukucatshangelwa kokuphepha kuphoqa ukuthi isitoreji sebhethri sisetshenziswe kanjani futhi sikhulu kangakanani. Umlilo wangoJanuwari 2025 we-Moss Landing e-California waphoqa ukuthi kuphume abantu abangu-1,500 futhi kwavuselela ukukhathazeka komphakathi mayelana nokubaleka kokushisa kumasistimu e-lithium{4}}. Iziphathimandla ezimbalwa, okuhlanganisa nezingxenye ze-New York, zenze umthetho wokumisa amaphrojekthi amasha ebhethri ngenkathi kuthuthukiswa amakhodi omlilo abuyekeziwe.
Ukufakwa kwesimanje kusebenzisa amadizayini esitsha semodular anezidingo zezikhala ukuze kuvinjelwe ukubhebhetheka komlilo, kodwa amaphrojekthi amadala awanazo lezi zivikelo. Izinga lokucisha elimaphakathi lomkhakha ngo-2024 lalingu-5.8% womthamo we-nameplate kumabhethri e-CAISO-angatholakali ngenxa yokunakekelwa, amaphutha, noma ukukhathazeka kokuphepha lapho igridi iwadinga kakhulu.
Izithiyo zezinto zenza-umbuzo wesikhathi eside. Ukunikezwa kwe-lithium kunwebeka ngo-12% ngonyaka kuze kube ngu-2030 ngokusho kukaGoldman Sachs, kodwa lokho kukhula kufanele kuhambisane nesidingo esikhulayo sama-EV kanye nesitoreji esimile. Ukuthola i-Cobalt evela e-Democratic Republic of Congo kuphakamisa izingqinamba zokuziphatha kanye nokusimama kwe-supply chain. Abakhiqizi abaningi baye bashintshela kumakhemikhali e-lithium iron phosphate (LFP), eqeda i-cobalt kodwa inikeza amandla amancane aphansi.
Ukucindezelwa kwemali engenayo ezimakethe ezikhulile kuhlela kabusha umnotho wamaphrojekthi. Isilinganiso semali engenayo yemakethe ku-CAISO yehle ngo-35% ngo-2024 yafinyelela cishe ku-$51,000 ngonyaka-ngonyaka njengoba umthamo webhethri ukhula ngokushesha kunerenti yokushoda. Amabhethri angaphambi kwesikhathi athwebule amanani eprimiyamu ngokuba abahambisi bokuqala ezimakethe zesevisi ezisizayo ezinenzuzo enkulu. Njengoba amabhethri amaningi egcwala, lezo zimakethe ziyagcwala, okuphoqa amabhethri ukuthi aqhudelane{8}}nge-margin energy arbitrage ephansi.
Amaphrojekthi anenzuzo ngokuya ngokuya endaweni. Amabhethri ngemuva kwezindawo zokudlulisela eziminyene, lapho isizukulwane sasendaweni siyindlala, iyala amaprimiyamu. Amabhethri ezindaweni ezinokushintshashintsha kwentengo okwedlulele{2}}njengemakethe yase-Texas engalawulwa{3}}angabuyisa izindleko zekhephithali ngokushesha. Amabhethri ajwayelekile-ezimakethe eziguqukayo eziphansi alwela ukuthethelela izindleko zawo zokwakha ngisho namanani entengo ehardware ehlayo.
Kusho Ukuthini Lokhu Ekuthembekeni Kwegridi
Isitoreji sebhethri sesilinganiso esikhulu seqe umkhawulo ukusuka entweni entsha ukuya esidingweni -emagridi avuselelekayo. I-California kanye ne-Texas-okuhlangene okuhlanganisa u-61% wokufakwa kwebhethri yase-US ngo-2024-ayisahlangabezana nezinkinga zokwethenjelwa ehlobo ezaziyinjwayelo eminyakeni emithathu nje edlule. Lokhu akukona okucatshangelwayo; kukalwa ngokucisha ugesi okugwenyiwe nangezintengo eziphansi ngesikhathi obekufanele kube imicimbi yokucindezeleka kwegridi.
I-US yengeze u-12.3 GW womthamo webhethri ngo-2024, okwenza umthamo ofakiwe usuphelele udlule ku-30 GW uma ihlanganisa{5}}-amasistimu wamamitha. Ukuqagela kubiza u-81 GW wokufakwa okwengeziwe kusukela ngo-2025 kuya ku-2029. Ngaleso sikali, amabhethri azoba ingqalasizinda ebalulekile, hhayi okungeziwe.
Kodwa "umthwalo wokubamba" uhlala uncike{0}}kumongo. Okwesikhathi esizayo esiseduze-iminyaka emihlanu elandelayo-10-isitoreji sebhethri esikhulu kunazo zonke sihamba phambili ekuhambeni ngamabhayisikili nsuku zonke kanye nokusabela okusheshayo. Azonika amandla amagridi ukuthi afinyelele ukungena okungu-60-70% okuvuselelekayo ngokuthembekile. Ngalé kwalowo mkhawulo, uqala ukudinga izixazululo amabhethri angakwazi ukuhlinzeka ngazo ngokwezomnotho: isitoreji sesizini, ikhophi yasenqolobaneni yamaviki amaningi, noma izinhlobo zesitoreji sesikhathi eside ezingekho esikalini sezentengiso okwamanje.
Ushintsho lwenzeka ngokushesha kunokubikezela okuningi okubikezelwe. Ngenkathi ibhethri le-Hornsdale lingena ku-inthanethi ngo-2017, abangabazayo bakubiza ngokuthi i-PR stunt. Eminyakeni eyisikhombisa kamuva, amabhethri ahlinzeke ngenani elingaphezu kwengxenye yesihlanu yesidingo esikhulu emnothweni wesihlanu{3}}omkhulu emhlabeni ngesikhathi sokushisa. Lokho akusona isiga-kuyingqalasizinda.
Izici Zokusebenza Eziyinhloko
Okuhlukile okuningana kunquma ukuthi isitoreji sebhethri sesikali esikhulu singakwazi yini ukusingatha ukulayisha kumongo othize:
Ubude Besikhathi Ukufanisa: Uma isikhathi sokufunwa kwakho okuphezulu sithatha amahora angu-3 ngosuku, amabhethri amahora angu-4 asebenza kahle. Uma ubhekana neziqongo zakusihlwa zamahora angu-8 ebusika lapho ilanga libuthakathaka, udinga isikhathi eside noma wamukele ukumbozwa kancane.
Ukujula Kokukhipha: Amabhethri alinganiselwe ngo-100 MW angakwazi ukugcina lokho okukhiphayo, kodwa kuphela isikhathi sawo esilinganiselwe. Ibhethri engu-100 MW / 400 MWh iletha i-100 MW amahora angu-4, noma i-50 MW amahora angu-8, kodwa hhayi i-100 MW amahora angu-8.
Ukuphathwa Kwesimo Sezimali: Umsebenzi-womhlaba wangempela udinga ukugcina amabhethri eshajwe kancane ukuze uphendule izehlakalo ezingalindelekile. Ibhethri elishajwa ngokugcwele phakathi nezinsuku ezishibhile zelanga lingase likhiphe u-30% phakathi nokwenyuka kwentengo yantambama, okushiya kuphela u-70% ukuphakama kwakusihlwa-kwehlisela umthamo osebenzayo uma kuqhathaniswa nezilinganiso ze-nameplate.
Impilo Yomjikelezo: Iziqinisekiso zebhethri ngokuvamile ziqinisekisa imijikelezo engu-4,000 ukuya kwangu-6,000 ngaphambi kokuba umthamo wehle ufike ku-80% woqobo lwangempela. Uma ujikeleza nsuku zonke, leyo iminyaka eyi-11-16 yokusebenza. Ukukhishwa okujulile noma ukuhamba ngebhayisikili kaningi kusheshisa ukuwohloka.
Ukuzwela kwezinga lokushisa: Ukushisa okukhulu nokubanda kunciphisa kokubili umthamo otholakalayo nempilo yomjikelezo. Amabhethri e-Arizona adinga ukuphathwa okushisayo okunolaka kunalawo asezindaweni ezipholile, okwengeza ezindlekweni zokusebenza.
Ukuqonda okubalulekile ukuthi ukuphatha umthwalo webhethri akuyona into kanambambili. Akukhona ukuthi "bangakwazi" noma "abakwazi"-"kungaphansi kwaziphi izimo futhi isikhathi esingakanani." Impendulo iya ngokuya ithi: yebo, ngezinhlobo zokuphathwa komthwalo amagridi amaningi adinga isikhathi esiningi.
imibuzo ejwayelekile ukubuzwa
Igridi{0}}ingakwazi ukukala isikhathi esingakanani amabhethri empeleni alayishe?
Amasistimu amaningi okugcina amabhethri amakhulu afakwe ngo-2024 angaphuma ngamandla aphelele alinganiselwe amahora angu-2 kuya kwangu-4. Ibhethri elingu-100 MW elinamandla angu-400 MWh lingaletha i-100 MW ngokuqhubekayo amahora angu-4 ngaphambi kokuphelelwa amandla. Kodwa-ke, opharetha abavamile ukuwasebenzisa ngokugcwele amabhethri{9}}bagcina amamajini abekiwe ukuze baphendule izehlakalo zegridi ezingalindelekile. Ukukhishwa kwangempela{11}komhlaba ngokuvamile kusuka ku-60-80% womthamo wethiyori.
Kwenzekani lapho isitoreji sebhethri siphela ngesikhathi sokufunwa okuphezulu?
Ama-opharetha egridi aphatha isimo sebhethri-sokushajwa{1}}ukuze kunqandwe ukuncipha okuphelele phakathi namahora abucayi. Emisebenzini yase-California yango-2024, isofthiwe yemakethe ithuthukisa ukuthunyelwa kwebhethri usuku lonke, ishaja{4}}ngamahora aphansi entengo elanga elanga futhi igcine ukukhishwa ngezikhathi eziphakeme ezaziwayo. Uma isidingo sidlula izilinganiso, opharetha bangabiza amajeneretha endabuko njengekhophi yasenqolobaneni. Ubungozi akuwona ukuthi amabhethri asike ngokuzumayo{7}}amabhethri afika ngamahora aphakeme ephele kancane ngoba asheshe ashajwe lapho amanani enyuka ngokungalindelekile.
Ingabe amabhethri angakwazi ukuthatha indawo yezitshalo zegesi yemvelo ngokuphelele?
Ukuze uthole ukushefa okuphezulu kwansuku zonke kanye nokusabela okusheshayo, ukugcinwa kwebhethri kwesilinganiso esikhulu sesivele singena esikhundleni sesidingo seziqongo zegesi ezintsha ezimakethe ezimbalwa. I-Texas neCalifornia zagunyaza izitshalo zegesi ezintsha ezimbalwa ngo-2024 naphezu kokukhula komthwalo omkhulu, zithembele ekufakweni kwebhethri. Nokho, ukushintshwa okuphelele kubhekene nemikhawulo. Izitshalo zegesi zingasebenza ngokuqhubekayo izinsuku lapho kudingeka, kuyilapho amabhethri angu-4-amahora engakwazi. Kuze kube yilapho isitoreji sesikhathi eside sisebenza ngokwezomnotho, amagridi amaningi azogcina ukukhiqiza okushisayo okungathunyelwa njengomshuwalense ngokumelene nokushoda okunwetshiwe kokunikezwayo.
Kungani bengakhe nje amabhethri amakhulu isikhathi eside?
Ubude besikhathi sokuvinjelwa kwezomnotho. Ihora ngalinye elengeziwe lomthamo wesitoreji lengeza izindleko ezibalulekile-cishe u-$150-200/kWh webhethri ngokwalo kanye nebhalansi{4}}yezindleko zohlelo. Ibhethri lamahora angu-8 libiza cishe ngokuphindwe kabili kunebhethri lamahora angu-4 lokuphuma kwamandla okufanayo. Nokho lelo bhethri lamahora angu-8 lingenisa kuphela imali ngesikhathi semicimbi engavamile lapho izintengo zihlala ziphezulu isikhathi eside. Amabhethri amaningi azuza ukubuyiselwa imali yawo ngomjikelezo owodwa wansuku zonke, okwenza izindleko ezengeziwe zesikhathi eside kube nzima ukuzithethelela ezakhiweni zemakethe zamanje.
