The era of "mega" and "giga" batteries has finally arrived in continental Europe, with hundreds of MW or even GW range-projects being announced on a regular basis. At the same time, durations are also increasing as revenue stacking becomes increasingly important with ancillary services saturating in key markets. Energy storage projects that enable "virtual transmission" are also growing in importance to address grid congestion as more and more renewables come online. Solutions are being sought across the continent for cost control, energy security and increased sustainability. In this session, we will take a closer look at some of the most interesting energy storage projects that reflect key industry trends in Europe, examining their set-up, drivers, economics, challenges and significance for the energy storage sector.
