Olga Sypula, VP and regional director for Central Europe at developer and IPP European Energy, shares her views on the key trends, opportunities and challenges across the Central and Eastern Europe (CEE) energy storage market.

Another roundup of user-posted hot takes and analysis from the energy storage industry recently.

We recently caught up with Georg Gallmetzer, managing director of German BESS platform Eco Stor, about the firm’s role in formulating flexible connection agreements (FCAs) and how this was intimately tied to the debate on grid fees. 

IPP Greenvolt Power has started building its Siedlce battery storage project in Poland, while Gore Street, Taaleri Energia and DS1 have moved to construction on projects in Poland, Estonia and Lithuania respectively. 

A flurry of project completions, financings and supplier deals for large-scale BESS across the Central and Eastern Europe (CEE) region, from Greenvolt, Renovatio & CATL, Eurowind, Renalfa, MOL Group, Tavion, MetaWealth and Enexus & Longi. 

Nearly 21GWh of grid-scale BESS came online globally last month, of which around a fifth was in Saudi Arabia while the majority was in China. 

RWE has taken a final investment decision (FID) on 400MW/1.1GWh BESS in the Netherlands with construction to start in due course, while Giga Storage has started building its 2.8GWh Green Turtle project in Belgium.

Poland’s grid-scale storage market has reached an impressive scale in the last few years, helped by the capacity market and various government schemes, but numerous challenges now need to be overcome.

System integrator Fluence and lithium-ion battery OEM Eve Energy have struck a massive 206GWh battery supply framework agreement for 2027-31, one of the largest deals of its kind ever announced.
