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.

Real estate developer ERNE Gruppe and architecture firm FlexBase are hoping to start construction on a data centre project in Switzerland next year, which will include a ‘non-flammable and non-explosive’ 500MW energy storage unit.

Investor Return has acquired an energy storage development platform in Germany, Swedish optimiser Flower has bought another large-scale BESS project, while Romania’s CIS Group has revealed a flurry of solar and storage projects.

A project in China, claimed as the largest flywheel energy storage system in the world, has been connected to the grid.

Three-quarters of the lithium-ion battery supply chain could have exposure to forced labour, contravening US and EU laws and potentially leading to products being blocked from those markets, a report said.

Stem Inc has seen its CEO step down while Energy Vault has been warned by the NYSE over its low share price, in a double helping of unfortunate announcements from SPAC-listed energy storage firms.

DNO and IPP Electrica has received €3.4 million (US$3.8 million) in EU grants for a c.70MWh BESS project it will build in Romania.

It was a busy week of news in the UK’s grid-scale energy storage market last week, with BESS projects put into operation by Eku Energy and Harmony Energy Income Trust (HEIT), and projects in the gigawatt-hour scale announced by ESB and Apatura in Scotland.
