Ngokutsho kwe-US Energy Information Administration, i-US ine-4,605 megawatts (MW) yokugcinwa kwamandla ebhetri amandla okugcina amandla ekupheleni kwe-2021. Umthamo wamandla ubhekisela kubuninzi bamandla onokuthi ibhetri ikhulule ngexesha elithile.
Ngaphezulu kwe-40% yomthamo wokugcina ibhetri osebenza e-US ngo-2020 unokwenza zombini iinkonzo zegridi kunye nezicelo zokudlulisa umthwalo wamandla.Ngokumalunga ne-40% yogcino lwamandla lusetyenziselwa kuphela ukuhanjiswa komthwalo wamandla, kwaye malunga ne-20% isetyenziselwa kuphela iinkonzo zegridi.
Umndilili wexesha leebhetri ezisetyenziselwa iinkonzo zegridi lifutshane (umndilili wobude bebhetri lixesha elithathayo ukuba ibhetri inike amandla ombane phantsi komthamo wamandla we-nameplate yayo de iphele);Iibhetri ezisetyenziselwa ukuhanjiswa komthamo wamandla zinexesha elide ngokwentelekiso.Iibhetri ezihlala ngaphantsi kweeyure ezimbini zibhekwa njengeebhetri ezifutshane, kwaye phantse zonke iibhetri zinokubonelela ngeenkonzo zegridi ezinceda ukugcina ukuzinza kwegridi.Iibhetri ezibonelela ngeenkonzo zegridi zikhupha ngexesha elifutshane, ngamanye amaxesha nakwimizuzwana embalwa okanye imizuzu.Ukusetyenziswa kweebhetri zexesha elifutshane zokugcina amandla kuqoqosho, kwaye uninzi lwebhetri yebhetri efakwe ekupheleni kwe-2010 yayiquka iibhetri zexesha elifutshane zokugcina amandla kwiinkonzo zegridi.Kodwa ekuhambeni kwexesha, lo mkhwa uyatshintsha.
Iibhetri ezinobude obuphakathi kweeyure ezi-4 nezisi-8 zidla ngokuqhutywa ngebhayisekile kanye ngemini ukuze kususwe amandla ukusuka kumaxesha omthwalo ophantsi ukuya kumaxesha omthwalo ophezulu.Kwindawo enomthamo ophezulu wokuvelisa amandla elanga, iibhetri ezirisayikilishwa yonke imihla zinokugcina umbane welanga emini kwaye ziphume ngexesha leeyure zomthwalo omkhulu xa umbane welanga usihla ebusuku.
Kulindeleke ukuba ekupheleni kwe-2023, inani lokugcinwa kwebhetri e-United States liya kwanda nge-10 GW, kwaye ngaphezu kwe-60% yamandla ebhetri iya kusetyenziswa ngokubambisana nezityalo zamandla elanga.Ukusukela ngo-2020, uninzi lwezixhobo zokugcina ibhetri ezifakwe kwizibonelelo zelanga zisetyenziselwa ukuhambisa umthwalo wamandla, kunye nobude bexesha elingaphezu kweeyure ze-4.
