Industry experts discussed the varying approaches in Europe to procuring energy storage via long-term support schemes on Day One of Solar Media’s Energy Storage Summit 2025 in London, which kicked off today (18 February).

“Short duration flexibility has a massive role to play in reducing the costs of the Great British energy system, saving £10 billion a year by 2050,” Duncan Stone said this morning at the Energy Storage Summit 2025 in the UK.

Germany is currently the “hottest market in Europe today from a development perspective,” according to battery storage developer-investor BW ESS.

The Gore Street Energy Storage Fund (GSF) was one of the early movers in the UK BESS industry and now has operational assets in Great Britain (GB), Ireland, Germany, Texas and California.

The energy storage market in Italy has unique characteristics that mean more risk-averse investment funds will be able to enter, but upcoming auctions could be very competitive, driving down clearing prices, a director at consultancy Timera Energy said.

Modo Energy’s Wendel Hortop tells Energy-Storage.news that over 4GW of utility-scale BESS on the NEM will be in commercial operation by 2025.

Tesla and Sumitomo Electric have both been selected to supply energy storage projects in Japan. Tesla will supply Megapacks for a BESS project while Sumitomo will deploy a 12MWh vanadium flow battery.

The government of Estonia will financially back a 500MW pumped hydro energy storage project to meet the country’s need for long-duration energy storage, as the Baltics prepare to disconnect from Russia’s grid this weekend.

Eku Energy’s chief technology officer, Elias Saba, discusses the shift in economics of long-duration BESS in Australia’s NEM.
