Ngokusho kwe-US Energy Information Administration, i-US inamamegawathi angu-4,605 (MW) womthamo wamandla ebhethri okugcina amandla ekupheleni kuka-2021. Umthamo wamandla ubhekisela enanini eliphezulu lamandla ibhethri elingawakhulula ngesikhathi esithile.
Ngaphezulu kuka-40% womthamo webhethri osetshenziswa e-US ngo-2020 ungenza zombili izinsiza zegridi kanye nezinhlelo zokusebenza zokudlulisa amandla.Cishe u-40% wesitoreji samandla usetshenziswa kuphela ekudluliseni umthwalo wamandla, futhi cishe u-20% usetshenziselwa izinsiza zegridi kuphela.
Isilinganiso sobude besikhathi samabhethri asetshenziselwa izinsizakalo zegridi sifushane uma kuqhathaniswa (isilinganiso sobude bebhethri isikhathi esisithathayo ukuze ibhethri inikeze amandla kagesi ngaphansi komthamo wamandla we-nameplate yayo ize iphele);Amabhethri asetshenziselwa ukudluliswa kwamandla anesikhathi eside uma kuqhathaniswa.Amabhethri ahlala ngaphansi kwamahora amabili abhekwa njengamabhethri esikhashana, futhi cishe wonke amabhethri anganikeza izinsizakalo zegridi ezisiza ukugcina ukuzinza kwegridi.Amabhethri ahlinzeka ngamasevisi egridi aphuma ngesikhathi esifushane, ngezinye izikhathi ngisho namasekhondi ambalwa noma amaminithi.Ukukhipha amabhethri okugcina amandla esikhathi esifushane ukonga, futhi iningi lomthamo webhethri elifakwe ngasekupheleni kwawo-2010 lalihlanganisa amabhethri esikhashana okugcina amandla ezinsiza zegridi.Kodwa ngokuhamba kwesikhathi, lo mkhuba uyashintsha.
Amabhethri anobude besikhathi obuphakathi kwamahora angu-4 nangu-8 ngokuvamile ajikeleziswa kanye ngosuku ukuze asuse amandla ezikhathini zokulayisha okuphansi aye ezikhathini zokulayisha okuphezulu.Endaweni enamandla amakhulu okuphehla amandla elanga, amabhethri agaywa kabusha nsuku zonke angagcina amandla elanga emini futhi aphume phakathi namahora omthwalo omkhulu kakhulu lapho amandla elanga ehla ebusuku.
Kulindeleke ukuthi ekupheleni kuka-2023, inani lokugcinwa kwebhethri e-United States lizokhula ngo-10 GW, futhi ngaphezu kwe-60% yamandla webhethri azosetshenziswa ngokuhambisana nezitshalo zamandla elanga.Kusukela ngo-2020, iningi lamathuluzi okugcina amabhethri afakwe ezindaweni zelanga asetshenziselwa ukudlulisa umthwalo wamandla, ngesilinganiso sobude besikhathi esingaphezu kwamahora angu-4.
