Colombia's first grid-scale battery energy storage system (BESS) came online in 2023 near Medellín – a 20MW/40MWh behemoth that's essentially a giant Tesla Powerwall for the national grid. Here's why it matters: Move over, oil.
[pdf] Zenobe Energy is the largest independent owner and operator of battery storage in the UK. It buys and manages grid-scale batteries for its commercial customers, such as utilities and electric-vehicle operators.
[pdf] Spanish ports are becoming a battleground for storage tech. CATL's new 20MW lithium installation in Bilbao boasts 92% efficiency, while upstart Volterion's vanadium flow batteries promise 25-year lifespans. The subsidy twist?
[pdf] A total of 120MW/140MWh of grid-scale battery energy storage system (BESS) capacity came online in January 2025, bringing the UK’s total operational capacity to around 6GW/8.3GWh. Meanwhile, the amount that is now under construction has reached 8.2GW/18.7GWh.
[pdf] In the United States, cumulative utility-scale battery storage capacity exceeded 26 gigawatts (GW) in 2024, according to our January 2025 Preliminary Monthly Electric Generator Inventory.
[pdf] As of recent estimates, the average cost is around $250 to $400 per kilowatt-hour (kWh) of storage capacity, equating to approximately $0.25 to $0.40 per watt, depending on system design and size.
