Vad händer
Kontext
Uppväxlingen skedde framförallt i Kalifornien och Texas, landets överlägset största producenter av fri energi.
Texas grid battery capacity surged from 275 megawatts in 2020 to 3,500 megawatts as of this summer, meaning the fleet grew 13 times larger in just three years.

Kalifornien har tiodubblat sin lagringskapacitet de senaste tre åren. Batterier utgör nu 7,6 procent av energisystemets kapacitet i delstaten.
Vad har det för betydelse
In terms of the transition to clean energy, this means that batteries are taking on more of the role served by fossil-gas peaker plants, which don’t run all the time but fire up for several hours at a time in response to high demand. Lithium-ion batteries today can only keep up their full-strength discharge for a few hours; that’s why numerous startups and the Department of Energy are pushing to commercialize long-duration storage technologies.
