Poland capacity auction to lead BESS deployments in Eastern Europe

Poland looks set to lead battery storage deployments in Eastern Europe, with 9GW of battery storage projects offered grid connections and 16GW registered for the ongoing capacity market auction.

Eastern Europe has languished behind other regions in developing battery storage, but this is set to change. Driven by falling costs of renewables, the closure of coal generation and the need to rapidly find alternatives to Russian gas, the accelerated installation of intermittent generation will lead to a rapid transition of their electricity markets. 

Where are we now?

At the end of 2023, Lithuania has the most operational capacity with the energisation of four 50MW installations owned and operated as a single battery park by Energy Cells. Hungary has a small number of installations just above 30MW, while Poland and Romania have little more than 10MW of operating capacity.

One of the largest barriers has been the lack of policy development and slow implementation of the Clean Energy Package to open ancillary services to market structures that would drive the development of storage. As a result, current capacity is dominated by pilot projects with strong network operator involvement.

This is particularly highlighted by Lithuania, where the project was driven by the Lithuanian TSO to support the national transmission network. Similarly, financing of these projects is often public (either national or EU level). Energy Cells, the operating company of the Lithuanian projects, is 100% owned by EPSO-G, whose sole shareholder is the Ministry of Energy of the Republic of Lithuania.
