I don’t really get it, in the chart “Installed grid-scale battery capacity in gigawatts, 2025”
Europe barely has like 17GW in total but later on below they say:
In Europe, it sees batteries that are already online or nearing completion as likely to benefit most, with capacity seen rising from about 50 gigawatts in 2025 to 75 gigawatts by year-end.
What is this big discrepancy? Is the second part talking about batteries not connected to the grid or something (not grid-scale?)
Seems to be the classic GW vs GWh struggle journalists cannot comprehend.
In 2025, the EU added around 12 GW of extra power output from batteries, and about 25 GWh of energy storage capacity to the already existing infrastructure.
Meaning the batteries can output 12 GW of power for more than 2 hours before they are depleted.
