6. Okusuubula ebifo by’amasannyalaze
Okusuubula mu kitundu ky’amasannyalaze kitegeeza enkola y’okusuubula ebitongole by’akatale nga kkampuni ezikola amasannyalaze mwe biwa eby’okugonjoola amasannyalaze mu ngeri y’okugula okugenderera akatale. Olw’obwangu bw’ennongoosereza mu katale k’amasannyalaze mu China, eggwanga lireese enteekateeka empya ennyo okukubiriza ebifo ebitereka amasannyalaze okwetaba mu katale k’ekitundu ky’amasannyalaze, wamu ne dizayini ya kkampuni empya ey’amakolero g’ebifo ebitereka amasannyalaze mu butuufu etandikiddwawo. 7. Ebigonjoola eby’amasannyalaze eby’okugatta
Empeereza ez’okuyambako ezisasulwa amasannyalaze g’amasannyalaze zitegeeza empeereza ez’okubiri eziweebwa oludda lw’okukola amasannyalaze oluyungiddwa ku mudumu eziyinza okukola ku mugugu ogukyukakyuka ogw’amasannyalaze okusindika ebiragiro (nga mw’otwalidde n’okukung’aanya nga biyita mu bakung’aanya, ekyuma kya nukiriya eky’omubiri, n’ebirala) nga kwotadde n’ebigonjoola eby’okubiri ebikulu.
Omuli: okulungamya frequency enkulu, okufuga okukola amasannyalaze mu ngeri ey’otoma, okusenya waggulu, back-up, okukyusa amasannyalaze agasasulwa agaddamu, black start n’empeereza endala ez’enjawulo eziyamba ezisasulwa zirina okuliyirira. Okutereka amaanyi mu makolero ne mu bizinensi kuyinza okukola ng’omukutu gw’amagoba omupya ennyo nga guwa obuweereza obuyambi mu katale k’amasannyalaze.
Okukula mu biseera eby’omu maaso abayinza okubeera bakasitoma b’ekitongole ky’okutereka amasannyalaze ag’ebyobusuubuzi n’eby’obusuubuzi
eggwanga lyange amasannyalaze aga photovoltaic oba pv gatonda mangu. Okuva mu January okutuuka mu September 2022, obusobozi obuteekeddwawo obw’amasannyalaze g’ekitangaala ag’amakolero n’ag’ettunzi bujja kutuuka ku 18.74 GW, okulinnya kw’omwaka ku mwaka ebitundu 278%, naye ate okutereka amaanyi ag’obusuubuzi ne mu bizinensi kukyali mu ntandikwa.
Okusinziira ku kuteebereza kwa BNEF, obusobozi bw’ensi yonna obupya obw’okuteekawo obusobozi bw’amakolero awamu n’obw’obusuubuzi obw’amakolero oba pv supporting energy storage space mu 2025 bugenda kuba 29.7 GWh. Mu makolero g’okugabira enjuba era ne bizinensi, nga olowooza nti ebbeeyi y’okuyingira mu kifo awaterekerwa amasannyalaze erinnya mpola, obusobozi bw’okuteekawo obusobozi bw’amakolero mu nsi yonna era n’amakolero ag’okutereka amasannyalaze g’enjuba agayimirizaawo mu 2025 busobola okutuuka ku 12.29 GWh.
Mu kiseera kino, wansi w’enteekateeka y’okugaziya enjawulo y’emiwendo gy’amasoboza ag’oku ntikko n’okuteekawo ssente z’amasannyalaze ez’oku ntikko, ebyenfuna by’okuteekawo okutereka amaanyi eri abakozesa amakolero awamu n’eby’obusuubuzi mu butuufu bitereezeddwa nnyo. Mu biseera eby’omu maaso, olw’okuzimba amangu akatale k’amasannyalaze akagatta mu ggwanga lyonna n’okukozesa tekinologiya w’amabibiro g’amasannyalaze ga nukiriya mu ngeri enkuze, okusuubula amasannyalaze mu kifo ekimu awamu n’okugonjoola amasannyalaze agayamba mazima ddala kijja kwongera okujja okuba eby’obugagga eby’ebyenfuna eby’ekifo eky’okutereka amaanyi mu makolero era n’eby’obusuubuzi.
Okugatta ku ekyo, okukendeeza ku nsaasaanya y’enkola z’ebifo ebitereka amaanyi mazima ddala kijja kulongoosa bulungi ebyenfuna by’ebifo ebitereka amasannyalaze mu makolero n’eby’obusuubuzi. Enkola zino ezikyukakyuka zijja kulanga okutondebwa okw’amangu okw’enkyusa z’empeereza y’okutereka amaanyi mu makolero era n’eya bizinensi mu mbeera ez’enjawulo ez’okukozesa, okutumbula okutereka amaanyi g’ebyobusuubuzi ne bizinensi nga kisoboka okukula okw’amaanyi.
