The global battery energy storage market is entering a new phase, with shifting cell prices, intensifying competition and rapid international expansion reshaping the supplier landscape.

We are pleased to announce that we’re now working on the 2027 edition of the Energy Storage Report, our annual publication looking at the big trends shaping the industry. 

EDF Power Solutions has put a 150MW/600MWh BESS in Belgium into commercial operation while Engie has started building a 74MW/296MWh project. 

BLUETTI, a technology pioneer in clean energy, today unveiled a new portfolio of products and intelligent energy solutions at IFA 2026.

A roundup of user-posted analysis, views and unofficial news from across the industry this past week, this time looking at this week’s sabotage attack on the German grid, BESS revenues and electricity market activity, CATL’s LFP price cut and various non-lithium news.

Inertia could provide a strong boost to BESS project returns in Germany, but operators are still waiting for the first prequalified inverters.

Bulgaria now has a world-leading amount of battery storage capacity relative to energy system despite a period of political turnover, although those assets are now cannibalising the revenues which attracted investment in the first place.

Power generator LEAG and its turnkey BESS construction partner HyperStrong have started building a 400MW/1,600MWh project in Germany, while Sunotec has done the same on a 441MWh project. 

BESS owner-operator BW ESS has progressed large-scale projects in Italy and Spain, totalling almost 1.2GWh and set to come online in 2027/28. 

Three years after the EU Batteries Regulation (EUBR) entered into force, it is becoming easier to separate regulatory expectations from measurable market impacts, writes patent lawyer Chloe Flower.
