IRENA's report emphasizes the importance of solar PV-based mini-grids with battery storage in achieving universal electricity access in West African nations like Burkina Faso, Mali, Nigeria, and Senegal. These mini-grids have the potential to serve over 21 million people and provide electricity access to 60-110 million people in scenarios where grid expansion is limited. The report introduces a "value of storage" metric, showing that integrating batteries into mini-grid systems can lead to cost savings and improved efficiency. Policy recommendations include deploying off-grid solutions, strengthening electrification planning, and creating an enabling environment for solar mini-grids with batteries to enhance energy security, lower costs, and transition away from diesel dependence, addressing the development and climate emergency caused by fossil fuel dependency and electricity access crisis.
