Falling battery costs can unleash Mexico’s full solar potential and boost energy security

This report by Ember analyzes Mexico's technical and economic potential to transition its electricity sector toward solar power and battery storage to reduce dependence on imported US gas. It argues that while Mexico possesses world-class solar resources capable of meeting the vast majority of its electricity demand, high local installation costs and regulatory barriers currently hinder this potential.

• Mexico possesses exceptional solar resources, ranking among the world's top 20 for solar potential with an average practical potential of nearly 4.9 kWh per 1 kWp installed per day. Simulations show that a 100 MW industrial facility could be powered nearly round-the-clock using 600 MW of solar capacity and 1,700 MWh of battery storage, with most locations achieving uninterrupted supply for over 300 days a year.
• Technically, solar power and battery storage could meet 90% of Mexico's total 2023 electricity generation using 190 GW of solar capacity and 600 GWh of battery storage, resulting in only 6% excess supply. Meeting 100% of generation is possible with 260 GW of solar and 950 GWh of storage, though this increases excess supply to 23%.
