Prefabricated Substation Solutions for Rural Power Grids in Africa: A Case Study of POWERTECH
1. Challenges in African Rural Power Grids
- Weak Infrastructure: Low electrification rates (20% in Sub-Saharan Africa), aging transmission lines, and 35% distribution losses.
- Funding and Technical Gaps: Annual investment needs of $40 billion, reliance on external loans, and skilled labor shortages.
- Environmental and Geographical Barriers: Harsh climates (heat, dust, humidity) and complex terrains (deserts, rainforests).
- Unreasonable Tariff Structures: Cost-revenue imbalance discourages grid expansion.
2. POWERTECH’s Prefabricated Substation Solutions
- Modular Deployment: Factory-preassembled components enable on-site installation within 48 hours.
