Liam Critchley examines the modelling, safety standards and analytics that aim to mitigate the risk of thermal runaway in lithium-ion battery energy storage systems (BESS).
The German network regulator’s decision to maintain grid fee exemptions for battery storage “ensures that billions in private investment remain directed” into the market, Energy-Storage.news has heard.
We hear from Clean Horizon about the consultancy’s European battery storage revenue index being added to Nord Pool’s Data Portal.
TagEnergy has commissioned a 240MW/480MWh project in France while Iberdrola has done the same with a 58MW/120MWh system in Spain, the two largest projects in each country. Meanwhile Engie, ACL Energy and Chint Solar Europe have moved to construction on projects in Belgium, Italy and Germany.
Germany’s energy system regulator has confirmed that BESS projects coming online by 4 August 2029 will be exempt from charging and discharging grid fees, opening up investment again after months of uncertainty.
While Germany is often described as the ‘hottest’ energy storage market in Europe, growing uncertainty on multiple policy and regulatory topics has led to a ‘cooling’ of investor interest.
The situation and uncertainty around grid connections and grid fees in Germany is evolving, possibly enabling market participants to look beyond the August 2029 grid fee exemption cut-off date – although uncertainty is still very high.
Lenders are increasingly willing to back large-scale BESS projects in Germany that don’t have any contracted revenues, although that merchant risk is priced in to structures, an executive at Aquila Clean Energy EMEA said.
Large-scale BESS projects have been progressed in Italy, Romania, Germany, Poland, Denmark and elsewhere in Europe, totalling around 1GW under construction, 1GWh soon to be, and another 1GWh at earlier stages.
BayWa r.e. will manage and maintain Germany’s largest operational BESS when it comes online later this year, while Terra One has started building a smaller project in the same state.
