Izibonelelo ezineshedyuli eziguquguqukayo ezikwaziyo ukushenxisa 30-40% yemithwalo ukuya-ixesha lencochoyi kufuneka ivavanye iinkqubo zebhetri ezisebenza iiyure eziyi-8-12 zokukhupha. Ixabiso eliphezulu langaphambili lifuna uhlalutyo olucokisekileyo lwe-ROI kodwa linikezela ngexabiso eliphezulu lexesha elide locwangciso lokusebenza 15+ i-horizons yonyaka.
Dibanisa ukhetho lokugcina kunye nophuculo lokusebenza{0}}ucwangciso lwemveliso olungcono, uphuculo lwezixhobo, kunye nokuphucula inkqubo kudla ngokuzisa imbuyekezo engaphaya kotyalo-mali lwenkqubo yogcino iyodwa. Ukugcinwa kwamandla oshishino kusebenza kakuhle njengenxalenye yesicwangciso esibanzi solawulo lwamandla kunokuba isisombululo esizimeleyo.
Iifektri ezininzi zifumanisa ukuba iindlela ezixubileyo-zelithiyamu{1}}iion yolawulo oluphezulu oludityaniswe neenguqu zokusebenza zokususwa komthwalo{2}}zibonelela ngembuyekezo engcono kunokwandisa iteknoloji enye. Esona sisombululo sixhomekeke kwizithintelo zakho ezithile, amathuba, kunye nezinto eziphambili kwishishini kune{4}}ubukhulu obunye{5}}bungena{6}}zonke iingcebiso.
Imibuzo ebuzwa qho
Ingakanani inkqubo yokugcina amandla kwimizi-mveliso edingwa ngumzi-mveliso?
Iimfuno zogcino lwasefektri ziqala kwi-200 kWh kumaziko amancinci ukuya kwi- 10+ MWh kubavelisi abakhulu. Ubungakanani bezibalo kufuneka bujolise kwi-70-80% ye-spike yemfuno yakho ephezulu kwiiyure ezi-2-4 zenkxaso. Isixhobo esine-500 kW yeencopho zeemfuno ngokuqhelekileyo sidinga umthamo we-1-1.5 MWh wokutsheva okusebenzayo.
Kuthatha ixesha elingakanani ugcino lwamandla kwimizi-mveliso phambi kokutshintshwa?
Iinkqubo ze-Lithium-zinikezela nge-7-iminyaka eyi-10 yokusebenza okusebenzayo phambi kokuba ukuthotywa kucuthe umthamo ongaphantsi kwemida ebonakalayo. Iibhetri ezihambayo zigcina ukusebenza kwe-20-25 iminyaka kunye nempompo kunye nokugcinwa kwecandelo. Obona bomi buxhomekeke kakhulu kubunzulu bebhayisikile kwaye ukukhwela ibhayisekile rhoqo kwandisa ubomi obude kakhulu.
Ngaba iifektri zingafaka iinkqubo zokugcina ngaphandle kwemvume yomsebenzisi wegridi?
Ngasemva-kwi{1}}ufakelo lwemitha olungathunyelelwanga ngaphandle kwigridi idla ngokufuna isaziso esiluncedo kodwa hayi imvume esesikweni kwimimandla emininzi. Iinkqubo ezithatha inxaxheba kwiinkonzo zegridi okanye i-net metering zifuna izivumelwano zokuqhagamshelanisa ezithatha iiveki ezi-4 ukuya kwezi-12. Izakhiwo zengingqi kunye neemvume zomlilo zihlala ziyimfuneko kungakhathaliseki uxhumo lwegridi.
Ngaba iinkqubo zokugcina amandla kwimizi-mveliso zikulungele ukufumana inkuthazo yerhafu?
I-Federal Investment Tax Credit ibonelela nge-30% yeekhredithi kwi-2032 yofakelo olufanelekileyo lokugcina ngaphezu komthamo we-5 kWh. Ukuhla kwexabiso le-MACRS kuvumela amashishini ukuba afumane kwakhona iindleko ngokuhla okukhawulezileyo kwi-5-yeminyaka esi-7. Inkuthazo yelizwe kunye nezinto eziluncedo ziyahluka kakhulu-iCalifornia, Massachusetts, kunye neNew York zibonelela ngeenkqubo ezongezelelweyo ngelixa amanye amazwe ebonelela ngenkxaso encinci.
