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.

The European Commission has approved a €1.2 billion (US$1.32 billion) state aid package for Poland to support the deployment of electricity storage facilities.

The decision to slash energy storage de-rating factors for the next capacity market auction in Poland will not be the death knell of the market, and may actually have some positives, project developers and IPPs said.

Flexibility will be a critical piece of the grid of the future and energy storage will play a central role in that, keynote speakers said at Solar Media’s Energy Storage Summit Central and Eastern Europe (CEE) 2024 today.

The Bulgarian Ministry of Energy began accepting applications yesterday (21 August) in tenders for 3,000MWh of energy storage capacity.

NGK Insulators, manufacturer of batteries and storage system based on sodium-sulfur (NAS) chemistry, has announced the commissioning of its first system deployed in Bulgaria.

The CEE energy storage market holds much promise but grants and subsidies might be needed to get it off the ground.
