Raws li Africa nrawm nws txoj hauv kev mus rau kev lag luam loj hlob, xav tau txhim khu kev qha, nqi-zoo, thiab muaj zog ruaj khov tau dhau los ua qhov tseem ceeb. Rau cov mining thiab kev lag luam hnyav tshwj xeeb, kev muaj hluav taws xob tsis yog tsuas yog kev ua haujlwm, tab sis yog tus tsav tsheb tseem ceeb ntawm kev tsim khoom thiab kev sib tw.

Tawm tsam qhov teeb meem no, Wenergy tab tom nthuav dav nws qhov chaw nyob thoob plaws Africa, xa lub zog cia-lub hauv paus microgrid daws teeb meem uas daws cov teeb meem tiag tiag hauv ntiaj teb tau ntsib los ntawm cov neeg siv khoom lag luam-txhim kho lub zog sib txawv, txo cov nqi, thiab txhawb kev hloov mus rau kev ua haujlwm qis.

Kev kov yeej "Zoo Island" txwv: Ntse Microgrids hauv Sierra Leone

Thoob plaws teb chaws Africa, ntau qhov chaw mining thiab chaw ua lag luam nyob deb ntawm cov nroog hauv nroog thiab tseem raug txiav tawm ntawm cov phiaj xwm hauv tebchaws. Cov no "Lub zog Islands" feem ntau vam khom rau cov tshuab hluav taws xob diesel-ua rau Cov nqi khiav lag luam siab, muaj kev pheej hmoo ntawm cov khoom siv roj, cov pa phem, thiab cov pa roj carbon emissions.

Hauv Sierra Leone, Wenergy tackles qhov kev sib tw no los ntawm a tag nrho off-grid hybrid hnub ci cia microgrid, centered rau nws Stars Series muaj kua-txias zog cia System (ESS). Teem sijhawm rau kev xa tawm los ntawm Lub Kaum Ob Hlis 2025, cov kev daws teeb meem suav nrog hnub ci PV, roj teeb cia, roj av thaub qab, thiab cov khoom siv mining hauv kev sib koom ua ke. Zog Kev Tswj Xyuas Lub Zog (EMS).

Los ntawm kev ua ntej hnub ci tsim, ntse xa tawm lub zog khaws cia, thiab txwv kev ua haujlwm diesel rau cov xwm txheej thaub qab, lub kaw lus xa ruaj khov, ua tau zoo, thiab qis-carbon zog haum rau cov kev xav tau ntawm cov chaw taws teeb mining. Nws modular thiab scalable architecture tsis tsuas yog txo tag nrho cov nqi hluav taws xob tab sis kuj tsim ib qho kev hloov pauv hloov tau rau yav tom ntej off-daim phiaj kev xa tawm thoob plaws West Africa.

Cov ntaub ntawv pov thawj cov ntaub ntawv thoob plaws teb chaws Africa

Ua ntej Sierra Leone, Wenergy tau ua tiav ntau qhov haujlwm hauv thaj av Southern Africa, ua kom pom kev ntseeg tau, scalability, thiab kev lag luam muaj txiaj ntsig ntawm nws cov kev daws teeb meem rau cov ntawv thov siab.

Zimbabwe: Loj-Scale Mining Microgrid

Hauv Zimbabwe, Wenergy tau siv hybrid microgrid rau kev ua haujlwm loj lithium mining uas yav tas los tso siab rau. 18 diesel generators, nrog cov nqi hluav taws xob ncav cuag USD 0.44 per kWh. Txawm hais tias daim phiaj hluav taws xob muaj nyob rau ntawm tus nqi qis dua, nws qhov tsis ruaj khov ua rau muaj kev pheej hmoo ua haujlwm tseem ceeb.

Txhawm rau daws qhov teeb meem ntawm tus nqi thiab kev ntseeg siab, Wenergy tau siv ib qho kev sib koom ua ke hnub ci PV + lub zog cia + diesel thaub qab + daim phiaj-txuas microgrid, ua ntej lub hnub ci zog thaum nruab hnub ua haujlwm thiab khaws cia lub zog ntau dhau rau kev siv hmo ntuj thiab lub sijhawm tsis tshua muaj irradiation, nrog cov roj diesel khaws cia nruj me ntsis raws li qhov xwm txheej.

• Phase I: 12 MWp hnub ci PV + 3 MW / 6 MWh ESS
• Phase II: 9 MW / 18 MWh ESS

Cov txiaj ntsig ntawm qhov project:

• Kwv yees 80,000 kWh ntawm kev txuag hluav taws xob txhua hnub
• Kwv yees li USD 3 lab hauv kev txuag nyiaj txhua xyoo
• Lub sijhawm them rov qab qis dua 28 lub hlis

Zambia: Metallurgical Kev Lag Luam Microgrid

Kev siv hluav taws xob tsis txaus ntseeg tseem yog qhov tseem ceeb ntawm kev tsim khoom thoob plaws Africa kev lag luam. Tsim los ntawm nws txoj kev mining microgrid hauv Zimbabwe, Wenergy nthuav dav nws cov kev daws teeb meem hluav taws xob tauj dua tshiab rau hauv Zambia kev lag luam metallurgical, qhov twg lub zog zoo thiab kev txuas ntxiv yog qhov tseem ceeb.

Qhov project site ntsib cov kab hluav taws xob tsis muaj zog thiab cov nqi hluav taws xob siab siab ntawm USD 0.30–0.50 per kWh, thaum metallurgical txheej txheem thov tshwj xeeb zog stability. Wenergy siv a solar-storage-diesel hybrid microgrid kev koom tes los ntawm kev tshaj lij EMS muaj peev xwm ntawm sub-10 millisecond qhov chaw hloov nruab nrab ntawm hnub ci PV, roj teeb cia, diesel thaub qab, thiab daim phiaj xa khoom thaum muaj.

Nplai: 3.45 MW PV + 7.7 MWh ESS

Cov txiaj ntsig tseem ceeb:

• Tag nrho cov nqi hluav taws xob txo rau USD 0.15–0.25 per kWh
• Ntau tshaj 70% txo nyob rau hauv diesel dependence
• Kwv yees li 1,200 tons ntawm CO₂ emissions txo txhua xyoo
• 3-5 xyoo ROI, ua raws li kev txuag nyiaj mus sij hawm ntev
• 24/7 txhim khu kev qha zog rau lub zog-intensive metallurgical txheej txheem

Saib Ua Ntej: Ua kom muaj kev lag luam decarbonization ntawm Scale

Ntawm Zimbabwe rau Zambia, thiab tam sim no Sierra Leone, Wenergy txuas ntxiv nthuav nws cov hneev taw thoob plaws Africa los ntawm lub zog cia-tsav microgrids uas daws cov teeb meem kev lag luam hauv ntiaj teb tiag.

Los ntawm kev sib xyaw industrial-qib ESS, ntse EMS, thiab kev paub txog kev sib koom ua ke, Wenergy pab cov neeg siv khoom txo cov nqi hluav taws xob, txhim khu kev ntseeg siab, thiab hloov mus rau kev ua haujlwm qis carbon, txhawb ob qho tib si Africa kev lag luam kev loj hlob thiab kev siv dag zog thoob ntiaj teb decarbonization.
