The three leading battery energy storage system (BESS) markets are identified in the fourth edition of Aurora's European Battery Markets Attractiveness Report, published March 3, 2025. Covering 28 markets, the report finds that Italy's target of 50 GWh battery capacity by 2030 focusing on PV Energy Storage, as well as the country opening up its ancillary markets to BESS, puts it ahead of the pack.
In the United Kingdom, Aurora estimated installed battery energy storage system (BESS) capacity on Great Britain's electricity grid would more than double by 2030, up from 4.3 GW to 10.6 GW. Northern Ireland is part of the Integrated Single Electricity Market (I-SEM) with Ireland. Germany has overtaken I-SEM to become the third most attractive market for BESS investment, according to Aurora, due to its "strong market outlook" and "ambitious" renewable targets. Belgium, Hungary and Greece were also identified as emerging "hotspots" for small-scale energy investors.
Taking Europe as a whole, Aurora Energy Research predicted grid-scale PV Energy Storage capacity will have a fivefold increase to 55 GW by 2030, up from 10.3 GW recorded by Aurora for October 2024. The longer-term projection in the battery market report predicts 126 GW of European grid-scale BESS by 2050. Aurora estimates that these capacity additions plus repowering projects will represent a EUR 100 billion investment opportunity through 2050.
