Isitoreji samandla senza ukuba khona kwaso kwaziwe kugridi kagesi yaseCalifornia njengoba ukushoda okucatshangwayo kunwebeka futhi kujula eminyakeni ezayo.(UDkt. Emmett Brown angase ahlabeke umxhwele.)

Umdlali omusha ugibele inkundla emakethe kagesi yaseCalifornia egcwele kakhulu.Faka isitoreji samandla se-lithium-ion.
Umhlaba wakubona lokhu kuvukela eminyakeni edlule, kodwa umfutho ubulokhu ukhula ngesivinini kusukela ehlobo lika-2019, lapho abalawuli baseCalifornia kanye nezinsiza kuqala.okubikezelwe ukushoda kwehora eliphakeme ngoSepthemba ka-2020.
Abalawuli baphawule ukuthi “ihora eliphakeme [lokudingeka kukagesi] onyakeni lenzeka ngokungaguquki ngoSepthemba… phakathi nehora eliphela ngo-17 (kusekelwe ku-PST noma ngo-6:00 pm PDT).Ngo-2022, inani eliphakeme lishintshela ehoreni eliphela ngo-18.”
Njengoba sibona eshadini (futhi kuphawulwe amabhokisi amhlophe achazwa ngokuthi “ukungenisa ngaphandle kwenkontileka”), kunamahora amathathu kuya kwamane lapho abalawuli babikezela khona ukushoda.
Ngo-2020, lokho kushoda kwafinyelela cishe ku-6,000 MWh emahoreni amathathu.Ngo-2021, abalawuli bangeze ihora futhi bakhulisa inani lokushoda phakathi newindi ngalinye lehora elilodwa, okuletha ukushoda okuphelele ku-14,400 MWh.Leyo nombolo yaphinde yakhula ngo-2021 yaya ku-15,400 MWh “yamandla angekho” emahoreni amane.
Ukuze ulawule ukushoda (kanye nokunxephezela isikhungo samandla enuzi esizovala), iCalifornia inqume ukwenza kanjalothola11.5 GW wokwanela kwensiza etholakala kumandla ahlanzekile ngo-2026. Lokho kumelela umthamo osheshayo, inombolo iningi lamasistimu okugcina amandla okufanele aligcine okungenani amahora amane.
Ukuthengwa kwempahla kudinga iphesenti elithile lalawo mandla ahlanzekile ukuze atholakale njengesitoreji sesikhathi eside, cishe amahora angu-10.Lokho kungase kuhumushele ngaphezu kuka-60 GWh wesitoreji samandla ahlanzekile esingezwe kugridi engxenyeni yeshumi leminyaka ezayo.
Lelo inani elikhulu lokugcinwa kwamandla esikhathini esizayo sase-California.Kodwa njengoba ososayensi besimo sezulu beqhubeka bezwakalisa ukukhala ngemililo yaseCalifornia ebangelwa isomiso esikhulu, kuyanda umuzwa wokuphuthuma.
Ngenhlanhla, i-2,000 MW yomthamo wokugcina amandla izofika ku-inthanethi ngo-Agasti 1, ngokusho kweKhomishini Yezinsiza Zomphakathi yaseCalifornia.Ingxenye enkulu yalo mthamo izoba namahora amane wamandla ebhethri ehlezi ngemuva kwayo, cishe i-8,000 MWh isiyonke.
Njengokubuka kuqala kokuthi lelo khono linikeza ini, sithola amazwibela ethu okuqala nge-California ISO Supply amashadi.
Ngomhla ka-9 Julayi ngo-6:30 PM, igridi eyinhloko yase-California yaphawula ukuthi isitoreji samandla sijove amandla angu-999 MW ngesikhathi "semcimbi oguquguqukayo" lapho ukucishwa kukagesi bekungenzeka ngenye indlela.
Qaphela izikhathi zokushajwa kwebhethri, nalapha.Njengoba amandla elanga e-California emini akhula, ukugcinwa kwamandla kuzoncipha kakhulu ugesi oshibhile kuze kufike lapho ukugcinwa kwamandla kungase kube umthamo oyisisekelo wokulayisha ngesikhathi sakusihlwa.
Esinye sezibonelo zokuqala zomcimbi omkhulu wokushaja senzeka ngoJulayi 14 ngo-9:15 AM, futhi silethwe ekunakekeleni kwethu i-California energy data geek.Joe Deely.Nansi indlela ebibukeka ngayo:
Ukuhlaziywa kwentengo kagesi omkhulu ngaleso sikhathi kungase kusinikeze inkomba yokuthi kungani la mabhethri akhethwa ukuthi ashaje ngalesi sikhathi.
Amabhethri amabili e-lithium ion amakhulu kakhulu emhlabeni anikele kulawa manani womthamo, futhi asekela igridi phakathi nomcimbi we-flex.
Eyokuqala yi-LS Power's230MW indawo yokugcina amandla e-lithium ion, obekuhlelwe ukuthi yenyuke isuka ku-230MWh iye ku-690MWh kuleli hlobo, futhi yengeze umthamo owengeziwe ngokuhamba kwesikhathi.Lesi sitshalo, umzuzwana noma kunjalo, singesinye segridi ye-lithium ion enkulu kunazo zonke emhlabeni exhunywe amabhethri.
Isikhungo sesibili yi-Moss Landing's300 MW / 1,200 MWh indawo- futhi, enye yezinkulu emhlabeni okwamanje - ejoyine igridi ngo-December 2020. Lesi sikhungo singase sikhule sibe ngu-1.5 GW / 6 GWh.
Masiqhubeke sonke, ngoba - akukude kakhulu esikhathini esizayo - sizobona 1.21 GW… Ukuzikhethela kuka-Doc Brown's flux capacitor.
