Although the government in Poland has taken steps to open up its energy storage market, regulatory challenges remain.

The Baltics is among the most attractive regions in Europe for battery energy storage system (BESS) investment right now, with the recent decoupling from Russia and increasing renewable energy use sending flexibility needs soaring.

Power firm PGE has started building a 262MW/981MWh BESS in Poland with LG batteries, coinciding with Solar Media’s Energy Storage Summit CEE, which kicked off today (23 September).

Fluence has deepened its partnership with Ukraine-headquartered energy company DTEK, agreeing to supply a large-scale battery storage project in Poland.

Ignitis Group and Olana Energy have progressed BESS projects in Lithuania closer to construction, with the order of equipment and final investment decision (FID) taken, respectively.

IPP DTEK Group and system integrator Fluence have together put a 200MW/400MWh BESS portfolio in Ukraine into commercial operation, a milestone praised by the country’s energy minister Svitlana Grinchuk.

European Commission funding is supporting a project to integrate battery storage at a pumped hydro energy storage (PHES) plant in Slovakia.

An EU-backed energy storage capex support scheme in Lithuania will support as much as 4,000MWh of battery storage, the Ministry of Energy has said.

Construction has begun in western Lithuania on a 30MW/60MWh grid-connected battery energy storage system (BESS) project using CATL equipment.

State-owned power generator and distributor PGE has launched a tender for the construction of a 2-hour BESS project in Poland.
