Insiza ephethwe ngabatshalizimali baseCalifornia i-San Diego Gas & Electric (SDG&E) ikhiphe ucwaningo lwemephu yomgwaqo ye-decarbonization. Umbiko uthi iCalifornia idinga ukuphinda kabili umthamo ofakiwe wezikhungo ezahlukahlukene zokuphehla amandla ezisebenzisayo ukusuka ku-85GW ngo-2020 kuye ku-356GW ngo-2045.
Le nkampani ikhiphe lolu cwaningo, “Umgwaqo Oya ku-Net Zero: Imephu Yomgwaqo yaseCalifornia eya eDecarbonization,” ngezincomo eziklanyelwe ukusiza ukufeza inhloso yezwe yokungathathi hlangothi kwekhabhoni ngo-2045.
Ukuze kuzuzwe lokhu, iCalifornia izodinga ukutshala amasistimu okugcina amabhethri anenani eliphelele elifakiwe le-40GW, kanye ne-20GW yezindawo zokukhiqiza i-hydrogen eluhlaza ukuze kuthunyelwe ukukhiqizwa, inkampani yengeza. Ngokwezibalo zakamuva zanyanga zonke ezikhishwe i-California Independent System Operator (CAISO) ngoMashi, cishe u-2,728MW wezinhlelo zokugcina amandla zaxhunywa kugridi esifundazweni ngoMashi, kodwa zazingekho izinsiza zokukhiqiza i-hydrogen eluhlaza.
Ngaphezu kokufakwa kukagesi emikhakheni efana nezokuhamba nezakhiwo, ukwethembeka kwamandla kuyingxenye ebalulekile yenguquko eluhlaza yaseCalifornia, kusho umbiko. Ucwaningo lwe-San Diego Gas & Electric (SDG&E) lwalungelokuqala ukufaka izindinganiso zokwethembeka embonini yezinsiza.
I-Boston Consulting Group, Black & Veatch, kanye noprofesa wase-UC San Diego uDavid G. Victor banikeze ukusekelwa kwezobuchwepheshe ocwaningweni olwenziwa yi-San Diego Gas & Electric (SDG&E).
Ukuze kuhlangatshezwane nezinjongo, iCalifornia idinga ukusheshisa ukususwa kwekhabhoni ngesilinganiso esingu-4.5 kule minyaka eyishumi edlule futhi iphindaphinde kane umthamo ofakiwe wokuthunyelwa kwezindawo eziphehla amandla ahlukahlukene, ukusuka ku-85GW ngo-2020 kuye ku-356GW ngo-2045, ingxenye yawo okuyizindawo zokuphehla amandla elanga.
Leyo nombolo ihluka kancane kudatha esanda kukhishwa yi-California Independent System Operator (CAISO). I-California Independent System Operator (CAISO) ithe embikweni wayo ukuthi i-37 GW yokugcina ibhethri kanye ne-4 GW yokugcina isikhathi eside kuzodingeka isetshenziswe ngo-2045 ukuze kufezeke umgomo wayo. Eminye imininingwane ekhishwe ngaphambilini iveze ukuthi amandla afakiwe ezinhlelo zokugcina amandla esikhathi eside adinga ukuthunyelwa azofinyelela ku-55GW.
Kodwa-ke, yi-2.5GW kuphela yezinhlelo zokugcina amandla ezitholakala endaweni yesevisi ye-San Diego Gas & Electric (SDG&E), futhi okuhlosiwe kwamaphakathi no-2030 kungu-1.5GW kuphela. Ekupheleni kuka-2020, leso sibalo sasingu-331MW kuphela, okuhlanganisa izinsiza kanye nabantu besithathu.
Ngokocwaningo lwe-San Diego Gas & Electric (SDG&E), inkampani (kanye neCalifornia Independent System Operator (CAISO) ngayinye inamaphesenti angu-10 omthamo wamandla avuselelekayo afakiwe okudingeka asetshenziswe ngo-2045) % ngaphezulu.
I-San Diego Gas & Electric (SDG&E) ilinganisela ukuthi isidingo saseCalifornia se-hydrogen eluhlaza sizofinyelela amathani ayizigidi eziyisi-6.5 ngo-2045, amaphesenti angama-80 awo azosetshenziselwa ukuthuthukisa ukuthembeka kokuphakelwa kukagesi.
Umbiko uphinde wathi ukutshalwa kwezimali okubalulekile kwingqalasizinda kagesi yesifunda kuyadingeka ukuze kusekelwe umthamo wamandla aphezulu. Ekwenziweni kwayo, i-California izongenisa u-34GW wamandla avuselelekayo kwezinye izifundazwe, futhi igridi exhumene entshonalanga ye-United States ibalulekile ekuqinisekiseni ukwethembeka kwesikhathi eside kohlelo lwamandla kagesi lwaseCalifornia.
