1. **非洲能源挑战**:近14亿人缺电(6亿无电,8亿供电不可靠),电网老化、债务高企,传统模式难以满足需求。 2. **互联微电网(IMG)价值**:结合本地可再生能源与国家电网,提升供电可靠性(如尼日利亚Toto项目供电从<3小时增至15小时/天),降低柴油依赖(刚果Goma项目柴油消耗降96%),实现“三方共赢”(开发商、消费者、公用事业)。 3. **规模化潜力**:尼日利亚IMG市场潜力达22GW(未来十年),可服务2500万用户;赞比亚、马达加斯卡等因弱电网、强需求、政策支持被列为高潜力市场。 4. **发展路径**:需市场评估、本地化商业模式、早期试点支持、政策优化及竞争性采购,加速IMG部署以推动非洲能源转型(SDG7、Mission 300目标)。
