January 31, 2026 – The world's first 400MWh energy storage station utilizing 628Ah ultra-large battery cells at scale was officially connected to the grid.
Cuba has transformed its electricity system in just 12 months, increasing solar power from 5. 8% to over 20% of total generation as the country races to escape dependence on oil imports now blocked by US sanctions.
This study introduces a novel comparison between three different configurations: (i) concentrated solar power (parabolic troughs + thermal energy storage + steam Rankine cycle); (ii) fully electric (PVs + wind + batteries); and (iii) an energy mix that combines both solutions.
