Developing countries face challenges related to energy imports, volatile prices, and fuel dependency, often leading to fiscal crises due to expensive thermal generators. Integrating renewable energy with storage systems offers a cost-effective solution, enhancing grid flexibility and reducing reliance on fuel-based generation. Private investment, facilitated by long-term power purchase agreements with independent producers, plays a crucial role. While still a small portion of the market, solar-plus-storage projects are growing rapidly, providing opportunities for developing countries to unlock private capital and reduce dependence on public funding, particularly focusing on utility-scale implementations.
