EDF Renewables has announced construction of a 50 MW Polish BESS. The site will be connected to the grid in the Opole region, in southwest Poland, with commissioning scheduled for the fourth quarter. The BESS will provide grid services.

The French utility made an initial move into Polish energy storage in March by acquiring the rights to a 200 MW/400 MWh BESS near the town of Turzyn from British investor Harmony Energy. The latter said it would reinvest the money into its Polish storage portfolio.

The latest grid capacity auctions held in Poland saw Parisian developer Qair secure energy storage projects in Kowala and Radkowice and EDF has announced another, 120 MW site, in Kobiernice.

India market data company Mordor Intelligence estimates Poland reached 25.08 GW of renewable energy generation capacity last year and expects the figure to rise to 50 GW by 2029, necessitating a rapid expansion of grid-connected energy storage projects.

Opinion & Analysis

Falling li-ion battery prices mirror solar photovoltaics trends: Is there a role for second-life batteries before recycling? Lithium-ion batteries are everywhere, powering everything from consumer electronics to electric vehicles, residential PV storage systems, and, more recently, mitigating curtailment in large-scale wind and solar power plants. EVs are driving large-scale demand for Li-ion batteries which will result in substantial volumes of spent batteries in the near future. This scenario highlights the potential for repurposing EV batteries for second-life stationary applications, which could maximise their value before recycling. However, to fully realise this opportunity, several economic, technical, and regulatory challenges must be addressed and resolved.
