Why most operators are stuck in a reactive cycle

-

Global battery storage capacity is set to nearly triple by 2030, and operators are already drowning in alarms. Valentin Lorscheid of ACCURE explains how to get ahead of problems, and why independent data matters.

Tankers at anchor – a reminder of the fossil-fuel exposure tracked in the Power Barometer 2026

Europe’s clean power passes a stress test, but flexibility gap widens

-

Eurelectric’s Power Barometer 2026 finds that clean electricity cushioned Europe from a fresh fossil-fuel shock this year, yet storage build-out is still falling well short of the pace needed to keep the system stable through 2030.

Storage on this scale is changing the maths for data centre power

S&P Global: batteries beat gas and diesel on data centre costs

-

Commissioned by Fluence, the study finds flexible capacity from a battery costs $371 million over 25 years in Texas – under a third of the price of gas and a sixth of diesel.
