The new digital twin from Brussels-based 3E, developed with the Free University of Brussels (VUB) under the Belgian government-funded FULLEST project, exposes a key oversight in Europe’s utility-scale battery storage management. While 80% of operators rely solely on battery management systems (BMS), 3E identified a 4% gap between reported and actual battery health – enough to affect operations and revenue.

Fluence is significantly expanding its manufacturing footprint in Vietnam, following delays in scaling its new production facilities in the United States.

The Lithuanian Ministry of Energy and Environment has approved additional funding for its energy storage procurement program after strong interest from potential beneficiaries. Meanwhile, Trina Storage has secured the first 180 MWh of battery projects in the country under its new gigawatt-hour-scale battery energy storage system (BESS) portfolio in the Baltics.

Moldova is expected to launch a new tender for the construction of large renewable energy parks colocated with battery energy storage systems in October.

In a major policy shift toward electricity market liberalization, China has introduced contract-for-difference (CfD) auctions for renewable plants and removed the energy storage mandate, which has driven up to 75% of national demand to date. S&P Global expects the move to reverberate through the global battery storage supply chain, further driving down prices already at historic lows.

Out of 6.9 GW of prequalified battery energy storage systems (BESS), equal to 1.9 GW derated capacity, about 1.8 GW of derated BESS secured 15-year contracts in the UK’s T-4 auction – nearly double last year’s volume. Just a week earlier, the T-1 auction also set a record for BESS procurement.

Sungrow’s new residential battery energy storage system features a compact 182 mm design and is capable of handling a maximum charge/discharge current of 50 A.

Sumitomo Electric’s new system comes in three versions, providing up to 10 hours of storage. It achieves improvements in output and energy density, through component enhancements, thereby reducing cost and physical footprint.

Only a day before cutting ties with the Russian power grid, Lithuania announced the launch of a major energy storage procurement exercise.

Researchers in China have reported a breakthrough in the development of aluminum-ion batteries. They have created a solid-state electrolyte that facilitates the smooth movement of aluminum ions, significantly improving battery performance and longevity.
