The United Kingdom has been named one of Europe’s top five markets for grid-scale battery storage investment, according to a new report by energy transition advisory firm Blunomy.
Joining Germany, Italy, Spain and Poland, the UK stands out for its policy support, stable revenue models, and mature energy trading environment.
Blunomy forecasts utility-scale battery capacity across Europe will nearly triple by 2030, rising from 39.6GW to 113.1GW. The UK is expected to play a central role in this expansion.
“Energy storage is no longer a ‘nice to have’ – it’s an essential pillar of any net zero energy system, especially as grids face increasing pressure. The UK combines market maturity, strong regulation and long-term returns. It’s one of the few European markets offering both immediate and sustained investment opportunities,” said Pierre Lelong, managing partner at Blunomy.
Key drivers of battery storage growth include variable renewable output, extreme weather events, bidirectional energy flows, and rising electricity demand from EVs and data centres. The UK’s appeal lies in long-term capacity contracts, strong trading margins, and supportive regulation.
Blunomy’s analysis ranks Germany, the UK and Italy as the most promising markets for battery storage investment. Delivering Europe’s projected growth could require £50–80 billion in investment by 2030, with the UK expected to attract a significant share.
The report also highlights a shift toward hybrid generation, where batteries are co-located with renewables to smooth output, reduce curtailment, and maximise clean energy delivery.
