What would the worldmap look like if country sizes reflected installed utility-scale battery capacity?

Well, it shows an extreme concentration in ‘developed economies’ (!), indicating that the potential value of energy storage is only exploited there. However, energy storage can have a transformative impact on ‘emerging and developing economies’ as well by reducing electricity cost, stabilizing weak power grids, or providing electricity access in the first place (see Energy Access).


This highlights the important role of smart business models and programs like the WorldBank Energy Storage Partnership (ESP) to make the potential value of energy storage accessible to 'emerging and developing economies'.
