The European energy storage industry has witnessed remarkable growth over the last decade, going from 9MW of project announcements in 2010 up to a total of 5,700MW in 2020 (year to date). Out of these projects, around 1.7GW are operational while the remaining 4GW are either announced or under construction (Figure 1).
Such uptake has been predominantly led by frequency control applications. However, things are changing as new revenue streams emerge and market prices tend to decrease.
