Izinsiza eziningi zezizwe ezisathuthuka zilandela le ndlela, njengoba kwenza ama-IPP aseNyakatho Melika athuthukisa isitoreji somthengisi ezimakethe ezincintisanayo zamawholesale lapho u-$/kWh enquma inzuzo.
Indlela yokuthuthukisa inaniibeka phambili abakhiqizi baseNtshonalanga noma abahlanganisi abayinkimbinkimbi-I-LG Energy Solution, i-Samsung SDI, i-Tesla, i-Fluence-ikhokha amaphrimiyamu angu-20-30% wesofthiwe ephakeme, amanethiwekhi esevisi asunguliwe, kanye nesiqiniseko sokuthobela imithetho. Ukuthengwa kwempahla e-Europe kuya kudinga lokhu ngenxa yezikhuthazo zokuqukethwe kwasekhaya kanye nemiyalelo yokusimama kwemibhalo. Amaphrojekthi engqalasizinda abalulekile ase-US athethelela izindleko ze-premium ngokuvikeleka kwe-supply chain kanye nokwesekwa kobuchwepheshe okusheshayo phakathi nezimo eziphuthumayo zegridi.
Indlela yesu yokuguquguqukaihlukanisa ukuthola amaseli kusukela ekuhlanganisweni kwesistimu, ukwenza inkontileka nama-EPC azimele anakekela umkhiqizi-izakhiwo zokuxilonga zisebenzisa amazinga e-IEEE 2030.5. Lokhu kuvumela ukunwetshwa okufakwe kusiteji ngobuchwepheshe obuthuthukayo-ukusetshenziswa kuka-2025 kungase kusebenzise amaseli e-LG, ukunwetshwa kuka-2030 kungase kuthathe{7}}ubuchwepheshe bezwe obuqinile obuphakeme ngaphandle kokushintsha ingqalasizinda ekhona. Le ndlela ihweba{8}}nomthengisi oyedwa kalula ukuze azivumelanise nezimo zesikhathi eside, ezifanele izinsiza ezinkulu ezinamathimba onjiniyela asezingeni eliphezulu akwazi ukuphatha imininingwane eyinkimbinkimbi.
Ayikho kulezi zindlela ezingcono kakhulu-inketho efanele incike{1}}ezithiyoni ezithile zephrojekthi mayelana nesabelomali, umugqa wesikhathi, izimiso, ukubekezelela ubungozi, nobunkimbinkimbi bobuchwepheshe. Abakhiqizi ababusa imakethe yomhlaba wonke ka-2025 894.4 GWh abawini ngobuhle bendawo yonke; bayaphumelela ngokuqhathanisa amakhono nezidingo zomthengi ezithize kangcono kunezinye ezisezingeni eliqhudelanayo.
Njengoba imakethe igijimela kumthamo ofakiwe ongu-250 GW ngo-2030, lindela ukuhlukana okuqhubekayo phakathi kwabakhiqizi bezinhlelo zokugcina amandla ebhethri. Umnotho waseShayina uzoqhubeka, ukuma kwe-Western premium kuzoqina ngokusebenzisa imisele yokulawula, futhi amakhadi asendle obuchwepheshe (isimo esiqinile-, i-sodium-ion,-ikhemistri yesikhathi eside) izodala izigaba ezintsha zochwepheshe. Abakhiqizi abasindayo akubona labo abakha ibhethri "elingcono kakhulu"{7}}yilabo abaxazulula izinkinga ezithile zamasegimenti ekhasimende achaziwe kangcono kunezinye izindlela, futhi bazivumelanise nezimo njengoba lezo zinkinga zishintsha.
U-19% wamaphrojekthi ahlangabezana nezinkinga zokusebenza awehluleki ngoba abakhiqizi abakwazi ukwakha amabhethri athembekile. Bayehluleka ngoba abathengi bakhethe okokusebenza okuthuthukiselwe izimo ezihlukahlukene zokusetshenziswa, amasistimu asetshenzisiwe ngaphandle kosekelo olwanele lobunjiniyela, noma bakhethe izindleko ngaphezu kwamandla kuzinhlelo zokusebenza lapho amandla ebaluleke kakhulu. Ukuqonda amakhono omkhiqizi{3}}hhayi nje amanani-okuhlukanisa amaphrojekthi e-BESS aphumelelayo ezifundweni ezibizayo ezindlekweni eziphelele zobunikazi.
Okuthathwayo Okubalulekile
Abakhiqizi besistimu yokugcina amandla ebhethri basebenza ngezigaba ezintathu: abakhiqizi bamaseli (CATL, BYD), izihlanganisi zesistimu (i-Fluence, i-Tesla), nabathuthukisi bephrojekthi, ngalinye linamandla ahlukile kanye nezinhlelo zokusebenza ezifanele.
I-CATL ihola umhlaba wonke ngesabelo semakethe esingu-37.9% kanye no-339.3 GWh esatshalaliswa ngo-2024, ibheke umthamo we-GWh ongu-670 ngo-2025, kanti i-BYD ilandela ngesabelo esingu-17.2% esirekhodiwe sesivumelwano se-Saudi esingu-15.1 GWh ngoFebhuwari 2025.
Imakethe yamaRandi ayizigidi eziyizinkulungwane ezingama-7.8 ka-2024 kulindeleke ukuthi ifinyelele ku- $ 25.6 billion ngo-2029 ku-26.9% CAGR, iqhutshwa yizidingo zokuhlanganisa ezivuselelekayo kanye neziyalezo zesimanje zegridi.
Ikhemistry ye-Lithium Iron Phosphate (LFP) ikhula ngo-19% CAGR ngo-2030, isusa i-NMC ezinhlelweni eziningi ngenxa yokuqina okushisayo okuphakeme kanye nezindleko eziphansi ngo-15-20%.
Amaphesenti ayishumi nesishiyagalolunye amaphrojekthi e-BESS athola ukubuyiselwa kwemali ngenxa yezinkinga zokusebenza-ukubambezeleka kokuthunyelwa, isimo-samaphutha{2}}yesilinganiso sezindleko, kanye nokungaqoqwa kwedatha okwanele kubukela phansi ubuchwepheshe obuzwakalayo.
Ukukhetha komkhiqizi kufanele kulinganisele izindleko zangaphambili nevelu yomjikelezo wempilo: amasistimu okuphatha amabhethri ayinkimbinkimbi, izinkundla zesofthiwe, amanethiwekhi wesevisi, nobunjiniyela bokuphepha komlilo kwehlukanisa abahlinzeki bemali ekhokhelwayo kubaholi bezindleko.
Ukungezwani kwe-geopolitical supply chain kuya ngokuya ngokwehlukanisa abakhiqizi baseShayina (inzuzo yezindleko) kwezinye izindlela zaseNtshonalanga (okuthandwa ngokomthetho), ngokwehlukana kwamandla okungenzeka kunwenwe ngo-2030.
Izinyathelo Ezilandelayo Ezinconyiwe
