Comparison of BESS optimization in Western Europe vs CSEE Guy Holding, enspired and Stella Zacharia, CEO, Optimus Energy 

Guy Holding (enspired) breaks down cross-market BESS optimization using live data from a German asset, making the case that performance warranties alone can add over €15 million across a project lifetime. Stella Zacharia (Optimus Energy) follows with Greek market data showing curtailment rates peaking near 15% in spring 2025, a clear signal that storage deployment is overdue.

The panel brings together all four speakers to tackle the big questions facing CSEE battery markets: how fast cannibalization will hit, why multi-market optimization is non-negotiable in shallow markets, what the Greek grid connection queue means for project timelines, and what separates a strong route-to-market partner from the rest.

The message is simple. The first movers who get assets live now will capture the best returns. The question is not whether cannibalization comes. It is whether you are already earning before it does.

An essential session for BESS developers, investors, and optimizers building a strategy in CSEE.
