2026 Grid-Ekifaananyi ky'akatale k'okutereka bbaatule za minzaani

Okutereka bbaatule kwayingira mu mwaka gwa 2026 oluvannyuma lw’omwaka omulala ogwa likodi ogw’okuteekebwa mu nsi yonna. Okusinziira ku...Ekitongole ky’ensi yonna eky’amasannyalaze ekya Global Energy Review 2026, 108 GW ez’obusobozi obupya obw’okutereka bbaatule zassibwa mu nsi yonna mu 2025, nga kino kyeyongedde ebitundu 40% okuva mu 2024. Ebitundu nga 80% ku busobozi obupya bwali bwa mutindo gwa mugaso-, ate bbaatule za lithium iron phosphate zaakola nga 90% ku kuteekebwa mu nkola.

Amerika nayo yatandika omwaka 2026 n’emirimu egya likodi buli luvannyuma lwa myezi esatu. OmuACP ne Wood Mackenzie Omulondozi w’okutereka amaanyi mu Amerikalipoota nti eggwanga lyassaawo 3.3 GW / 8.4 GWh ez’okutereka amaanyi ga bbaatule mu bitundu by’akatale byonna mu kwata y’okusooka eya 2026, 54% waggulu wa likodi eyasooka-quarter. Pulojekiti ez’omutindo gw’ebikozesebwa-zaali zikiikirira 2.3 GW / 6.8 GWh ku muwendo ogwo.

Payipu y’enkulaakulana ey’ekiseera ekitali kya wala-munene nnyo okusinga obusobozi obwatandika edda. Okusinziira ku...Ekitongole kya Amerika ekivunaanyizibwa ku by’amasannyalaze ekya United Energy Information Administration mu February 2026 mu biwandiiko bya jenereta, abakola bategese okwongerako GW 24 ez’okutereka bbaatule ku mutindo gwa utility-mu mu Amerika mu mwaka gwa 2026, bw’ogeraageranya ne likodi ya GW 15 eyamalirizibwa mu 2025. Texas, California, ne Arizona zikola ebitundu nga 80% ku by’okwongerako ebitegekeddwa, nga kuliko 12.9 GW mu Texas, 3.4 GW mu California, ne 3.2 GW mu Arizona.

Emiwendo gino ginnyonnyola emitendera egy’enjawulo egy’akatale era tegisaanidde kutwalibwa ng’egikyusibwakyusibwa. Omuwendo gwa IEA gupima obusobozi mu nsi yonna obwalagirwa mu mwaka gwa kalenda 2025 omujjuvu; omuwendo gwa ACP ne Wood Mackenzie gupima ebifo bya Amerika ebyamalirizibwa mu kwata y’okusooka eya 2026; era omuwendo gwa EIA gukiikirira abakulaakulanya obusobozi mu kiseera kino bateekateeka okutandika okukola mu mwaka gwa 2026 okusinga obusobozi obukola edda.

Payipu ya 2026 ky’etegeeza ku kugula pulojekiti

Okukula amangu mu kukola bbaatule kuyinza okukendeeza ku bbeeyi ya cell ne system, naye payipu ya pulojekiti ennene teggyawo bulabe bwa kutuusa. Pulojekiti eziwera eziyingira mu kuzimba mu kiseera kye kimu zisobola okwongera puleesa ku tulansifooma, switchgear, ebyuma ebya medium-voltage, abakola emirimu gya EPC abalina ebisaanyizo, okunoonyereza ku kuyungibwa, eby’obugagga by’okutandika okukola, n’enteekateeka z’okukkiriza ebikozesebwa.

N’olwekyo abakola balina okwekenneenya ekiteeso ku bbeeyi ya bbaatule esukka mu buli kilowatt-essaawa. Enteekateeka y’okugula era erina okukakasa ebiseera by’okukulembera tulansifooma ne PCS, ebikulu eby’okuyungibwa ku mudumu, okugezesa okukkiriza amakolero, obuvunaanyizibwa bw’okussa amaanyi mu kifo, eby’obugagga eby’okutandika okukola, ebyonoonese ebisaziddwamu, n’olunaku lw’okukola mu ndagaano ey’obusuubuzi-.
