Kwadalwa ngo 04.20
I. Ukuhlaziywa Kwezici Ezikhethekile Zemakethe Yase-Afrika
Imakethe yokugcina amandla e-Afrika ihlukile kakhulu kwezinye izindawo emhlabeni, ikakhulukazi ibonakala ngezici ezilandelayo:
- Ukushoda Okukhulu Kukagesi: Amanye amazwe ase-Afrika abhekana nokucinywa kukagesi njalo. Ngokwesibonelo, iZambia ingaba nokucinywa kukagesi okufika emahoreni angu-20 ngosuku, kanti iNingizimu Afrika yenza ukucinywa kukagesi okudlula izinsuku ezingu-200.
- Imvelo Yenani Lagesi Eliphezulu: Izindleko zikagesi zezimboni nezamabhizinisi zikhuphuke ngo-300% eminyakeni engu-5. ENingizimu Afrika, izindleko zifinyelela ku-R2.5/kWh (cishe ku-¥1/kWh), kanti izindleko zokukhiqiza ngedizili ziphakeme njengo-0.4-0.5/kWh.
- Amathuba Okuzuza Okukhulu: I-IRR emile yamaphrojekthi e-mining microgrid ingafinyelela ku-60%, i-IRR enyakazayo ingaba ngu-40%-50%, kanti inzuzo ye-EPC yebhizinisi le-solar-plus-storage ingaba ngu-40%-50%.
- Ukusekelwa Kwezinqubomgomo Okuhlukahlukene: Izinqubomgomo ziyahlukahluka ngezwe. INingizimu Afrika inikeza isibonelelo esingu-25% samaphrojekthi okugcina amandla, kanti iKenya inikeza ukukhululwa ezintweni zokungenisa kanye nentela yokwengeziwe.
II. Izinkomba Eziyinhloko Zezezimali Nezindlela Zokubala (Inguqulo Yase-Afrika)
1. Isilinganiso Esingaguquki Sokubuyisa Esikhokhelwe (ROI) Ifomula:
I-ROI = (Inzuzo Yonyaka Engenayo ÷ Izindleko Zokutshalwa Kwezimali Zizonke) × 100%
- Inzuzo Yonyaka Engenayo = Ukonga Ezindlekweni Zikagesi + Ukulahleka Okugwenyiwe Okubangelwa Ukuphazamiseka + Izibonelelo Zenqubomgomo - Izindleko Zokusebenza
- Isamba Sezindleko Zokutshalwa Kwezimali = Izindleko Zesistimu (kuhlanganise ne-premium) + Izindleko Zokwenza Ngokwendawo + Izindleko Zokuxhasa
2. Isikhathi Sokubuyisa Esingashintshi Ifomula:
Isikhathi Sokubuyisa Esingashintshi (iminyaka) = Izindleko Zokutshala Ezilindelekile ÷ Inzuzo Yonyaka Engenayo
Amaphrojekthi ase-Afrika asezingeni eliphezulu angathola izikhathi zokubuyisa ezifushane njengezinyanga ezingu-8 kuya eminyakeni emi-3.
3. Isilinganiso Sangaphakathi Sokubuyisa (IRR)
Izilinganiso ze-IRR zamaphrojekthi ase-Afrika ziphakeme kakhulu kunezindawo ezithile emhlabeni:
- Amaphrojekthi Ajwayelekile Ezohwebo Nezomkhakha: 18%-25%
- Amaphrojekthi Emigodi Yezimayini: 40%-60%

4. Inani Lamanje Elilindelekile (NPV)
Kufanele kucatshangelwe amazinga aphezulu okwehliswa (izindleko zokuxhasa ngezimali zase-Afrika zisukela ku-8% kuye ku-18%).
III. Ukwakheka Kwemali Engenayo Nokubalwa (Izici Zase-Afrika)
1. Imali Engenayo Yokonga Ezindlekweni Zikagesi (Ebalulekile) Ifomula:
Ukonga Okonyaka Ezindlekweni Zikagesi = (Intengo Yamandla Kagesi Enethiwekhi - Izindleko Eziyisilinganiso Zesitoreji) × Ukusetshenziswa Kwamandla Kagesi Konyaka
- Intengo Yamandla Kagesi Enethiwekhi: 0.2−0.4/kWh (umsebenzisi wokugcina)
- Izindleko Eziyisilinganiso Zesitoreji: 0.07−0.2/kWh (uhlelo lwe-solar PV + isitoreji)
- Ukonga Okubuyisela Idizili: Izindleko zokukhiqiza idizili zingama-0.37−0.5/kWh
2. Ukwehliswa Kwezimali Zokulahleka Kwe-Outage Formula:
Ukulahleka Kwe-Outage Okugwenyiwe Konyaka = Ukulahleka ngakunye kwe-Outage × Inani le-Outages Konyaka × Isilinganiso Sokugcinwa
- Inani Elijwayelekile: Ukulahleka kwe-Outage ezibhedlela nasezikhungweni zedatha kungafinyelela ku-$5,000 ngehora.
- Icala Lokumba: Ukulahleka kwe-Outage konyaka kwe-$2.4 million kungagwenywa ngokuphelele ngokusebenzisa ukugcinwa.
3. Imali Yokuhweba Kwe-Peak-Valley Formula:
Imali Yokuhweba Konyaka = Umehluko Wamanani We-Peak-Valley × Inani Lezinga Lokuhweba Kwe-Electricity Konyaka × Ukusebenza KweSystem
- Umehluko Wamanani We-Peak-Valley e-Afrika: 0.12−0.28/kWh (iTogo)
- Icala Elinzima: Umehluko wamanani we-Peak-Valley eZimbabwe ungama-3.83.
4. Imali Yokuxhaswa KwePolicy
- South Africa: 25% construction subsidy for energy storage projects.
- Kenya: VAT on lithium battery storage systems reduced from 16% to 8%.
- Mali: 10-year tax exemption for supporting energy storage projects.
