European energy storage initiatives are accelerating, driven by increased demand for grid stability and renewable integration. Germany, for example, has emerged as a major hub for battery energy storage projects (BESS), with new regulatory updates removing the “double-charging” fees for energy storage, a change that opens pathways for significant investment and large-scale developments. In particular, Germany is set to host the largest battery project in Europe, an initiative supported by revised energy policies that streamline approval processes and support flexibility in grid operations. Investors are keen to back large storage projects, anticipating both market growth and favorable regulatory shifts.

Several high-profile projects highlight the pace of BESS growth in Europe. In the Netherlands, the largest BESS project is underway, a 364 MW/1,457 MWh installation expected to come online in 2026. Germany’s ECO STOR is building a 600 MWh battery storage facility in Saxony-Anhalt, while Neoen and Nidec have collaborated on a substantial 9 MW/93.9 MWh facility in Sweden, marking the largest project of its kind in Northern Europe. Additionally, France and Italy have also expanded their BESS capacities, with numerous projects surpassing 100 MW.

This growth in BESS is paralleled by advancements in long-duration storage solutions across Europe, including compressed air storage (CAES) facilities, such as the 320 MW capacity Ahaus project by Corre Energy in Germany. With supportive policies and rising private investment, Europe is poised to significantly enhance its energy storage capacity over the next few years, establishing a resilient energy system that can better balance renewable fluctuations across the grid.
