Dan Taylor, director of engineering at optimisation and asset management provider Arenko, speaks to Energy-Storage.news about all things data in battery energy storage systems (BESS).

A trio of large-scale 4-hour BESS projects in Germany have progressed towards construction, from Enertrag and Enlight, Vattenfall and Fluence, and Giga Storage.

Around 20.4GWh of grid-scale battery energy storage systems (BESS) came online globally last month, bringing the year-to-date (YTD) total to 208GWh.

Metals and energy group Metlen and conglomerate Karatzis Group have inaugurated the largest BESS in Greece, in a ceremony attended by the country’s Prime Minister.

How similar is the technology of Exa Energy, which just connected a 100MW/1GWh carbon dioxide-based energy storage system to the grid in China, to that of Energy Dome?  

Insufficient progress has been made towards the Energy Storage and Grids Pledge, endorsed by dozens of countries at COP29 two years ago.

The expert judges’ difficult decisions to select winners from hundreds of worthy entries for the Energy Storage Awards 2026 are almost finalised.

A panel of BESS industry experts discussed the ins and outs of long-term service agreements (LTSAs) at the Battery Asset Management Summit UK & Ireland 2026 yesterday. 

Europe is no longer betting on second-life repurposing of EV batteries for stationary BESS applications, and that is not a bad thing, argues David Oudsandji, CEO of Voltfang.

Bankability & offtake and regulatory & system reform were the key talking points on the opening panel of the Battery Asset Management Summit UK & Ireland 2026 which runs today and tomorrow (13-14 October).
