Mugihe Afrika yihutisha inzira igana iterambere ryinganda, birakenewe ingufu zizewe, zihendutse, kandi zirambye yarushijeho kunenga. Ku bucukuzi bw'amabuye y'agaciro n'inganda ziremereye, kuboneka kw'amashanyarazi ntibikiri ibikorwa gusa, ahubwo ni moteri y'ingenzi yo gutanga umusaruro no guhangana.

Kuruhande rwinyuma, Wenergy igenda yiyongera muri Afrika, itanga ububiko-bushingiye kuri microgrid ibisubizo ibyo bikemura ibibazo nyabyo byugarije abakiriya binganda - gukemura icyuho cyingufu, kugabanya ibiciro, no gushyigikira inzibacyuho mubikorwa bya karubone nkeya.

Kunesha imbogamizi za "Ikirwa cyingufu": Microgrids nziza muri Siyera Lewone

Hirya no hino muri Afurika, ahantu henshi hacukurwa amabuye n’inganda biherereye kure yimijyi kandi bikomeza kuba bitandukanijwe na gride yigihugu. Ibi “Ibirwa by'ingufu” akenshi wishingikiriza cyane kuri moteri ya mazutu-bikavamo amafaranga menshi yo gukora, ibyago byo gutanga lisansi, kwanduza urusaku, hamwe na karuboni.

Muri Siyera Lewone, Wenergy ikemura iki kibazo ikoresheje a byuzuye-grid hybrid izuba-kubika microgrid, ishingiye kuri Inyenyeri Urukurikirane rw'inganda zikonjesha-Sisitemu yo kubika ingufu (ESS). Biteganijwe koherezwa bitarenze Ukuboza 2025, igisubizo gihuza izuba PV, ububiko bwa batiri, kubika mazutu, hamwe nubucukuzi bwamabuye y'agaciro munsi yubumwe Sisitemu yo gucunga ingufu (EMS).

Mugushira imbere imirasire yizuba, mubushishozi bwohereza ingufu zabitswe, no kugabanya imikorere ya mazutu kugarura ibintu, sisitemu itanga imbaraga zihamye, zikora neza, nimbaraga nke za karubone ijyanye n'ibikenewe mu bucukuzi bwa kure. Ubwubatsi bwa modular kandi bunini ntabwo bugabanya ikiguzi cyingufu zose ahubwo binashyiraho ibipimo byasubirwamo kugirango ejo hazaza hazoherezwa muri gride muri Afrika yuburengerazuba.

Byagaragaye ko amateka yavuzwe muri Afrika

Mbere ya Siyera Lewone, Wenergy yatanze neza imishinga myinshi yingenzi muri Afurika y'Epfo, kwerekana ubwizerwe, ubunini, nubukungu bushoboka bwibisubizo byabwo bikenewe cyane.

Zimbabwe: Microgrid nini yo gucukura amabuye y'agaciro

Muri Zimbabwe, Wenergy yashyize mu bikorwa microgrid ya Hybrid mu gikorwa gikomeye cyo gucukura lithium mbere yari ishingiye Amashanyarazi 18, hamwe n'amashanyarazi agera USD 0.44 kuri kilowati. Nubwo ingufu za gride zaboneka ku giciro cyo hasi, ihungabana ryayo ryateje ingaruka zikomeye kumikorere.

Kugira ngo ikibazo gikemuke kandi cyizewe, Wenergy yohereje hamwe izuba PV + kubika ingufu + kugarura mazutu + microcrid ihuza gride, Gushyira imbere ingufu z'izuba mugihe cyo kumanywa no kubika ingufu zirenze zo gukoresha nijoro hamwe nigihe cyo kurasa gake, hamwe na mazutu yagumanye nkibihe bidasanzwe.

• Icyiciro cya I: 12 MWp izuba PV + 3 MW / 6 MWh ESS
• Icyiciro cya II: 9 MW / 18 MWh ESS

Ibisubizo byumushinga:

• Bigereranijwe 80.000 kWt yo kuzigama amashanyarazi ya buri munsi
• Hafi USD miliyoni 3 mu kuzigama buri mwaka
• Igihe cyo kwishyura munsi y'amezi 28

Zambiya: Inganda zikora Microgrid

Amashanyarazi yizewe akomeje kuba imbogamizi yingenzi ku musaruro mu nganda za Afurika. Wenergy yifashishije ubucukuzi bwa microgrid yubucukuzi muri Zimbabwe, Wenergy yaguye ibisubizo by’ingufu zishobora kongera ingufu muri Inganda za Zambiya, Aho ubuziranenge bwimbaraga nubukomezi ari ngombwa.

Ikibanza cyumushinga cyahuye nibikorwa remezo bidakomeye hamwe nigiciro kinini cya mazutu USD 0.30–0.50 kuri kilowati, mugihe inzira ya metallurgiki yasabye imbaraga zidasanzwe zidasanzwe. Wenergy yashyize mu bikorwa a izuba - kubika - dizel hybrid microgrid bihujwe na EMS yateye imbere ishoboye sub-10 milisegonda yo guhinduranya isoko hagati yizuba PV, kubika bateri, kugarura mazutu, no gutanga gride mugihe ihari.

Igipimo: 3.45 MW PV + 7.7 MWh ESS

Ibisubizo by'ingenzi:

• Ibiciro by'amashanyarazi byose byagabanutse kugera USD 0.15–0.25 kuri kilowati
• Kugabanuka kurenga 70% biterwa na mazutu
• Hafi Toni 1200 z'ibyuka bihumanya ikirere byagabanutse buri mwaka
• Imyaka 3-5 ROI, hakurikiraho kuzigama igihe kirekire
• 24/7 imbaraga zizewe kubikorwa byimbaraga nyinshi

Kureba imbere: Gushoboza Decarbonisiyasi Yinganda Kumunzani

Kuva Zimbabwe to Zambiya, na ubu Siyera Lewone, Wenergy ikomeje kwagura ikirenge muri Afrika yose kubika ingufu - biterwa na microgrids ibyo bikemura ibibazo nyabyo byinganda zinganda.

Muguhuza inganda-zo mu rwego rwa ESS, EMS ifite ubwenge, hamwe nubuhanga bwo guhuza sisitemu, Wenergy ifasha abakiriya igiciro gito cyingufu, kongera ubwizerwe, no kwimuka mubikorwa bike bya karubone, gushyigikira iterambere ry’inganda muri Afurika ndetse nimbaraga za decarbonisation ku isi.
