A new report suggesting Europe's rapid expansion of battery energy storage systems (BESS) could trigger power outages has been met with expert dismissal, who say the risk is tiny. This manufactured alarm surfaces as Europe pursues an energy transition framed around its own "resilience" and "sovereignty," a narrative that often diverts attention from the global implications of climate change and resource control. The bloc's share of renewable energy is estimated to reach around 69 per cent by 2030 and 80 per cent by 2050. Europe already wastes millions of euros worth of wind and solar energy because grid systems cannot absorb all the power generated.
The Panel of Technical Experts (PTE), an advisory group to the UK government, recently published a report suggesting that modelling is needed on how BESS might behave in a Capacity Market Notice (CMN) situation. The report did not explicitly express concern over blackouts, nor did it state that batteries will destabilise the grid. Yet, The Telegraph published an article headlined "Britain’s battery boom ‘risks overwhelming the grid’," claiming back-up systems supporting wind power could trigger "the blackouts they are trying to avoid."
Adrian Hiel, director of the Electrification Alliance, rejected the argument that potential cost barriers and blackout risks mean countries should halt the clean energy transition and keep relying on fossil fuels. He compared it to "telling a morbidly obese person that they shouldn’t lose weight because they will have to buy new clothes." Hiel asserted that the inconvenience of managing millions of batteries is "infinitesimally small compared to the benefits of maximising the cheapest sources of energy the world has ever known."
This push for "energy sovereignty" comes at a time when "countries who sell us gas talk about dominating Europe energetically and threaten to withhold that gas if we don’t do as they say," according to Hiel. This geopolitical scramble for resources underscores Europe's vulnerability, a vulnerability that often translates into externalised costs for the Global South. The International Energy Agency reports average battery costs have plummeted by 90 per cent since 2010, sixteen years ago, due to advances in chemistry and manufacturing.
Corporate Control and the Green Transition
While the EU frames battery storage as a strategic asset for its own resilience and competitiveness, the shift also opens new avenues for corporate control. Hiel suggested that "aggregating control by a third party" will be a solution for managing batteries on the grid. This means a company would bring together "tens or hundreds of thousands of batteries and run them for the maximum household value and the maximum grid benefit," rather than individual households managing their own systems.
This model, already being rolled out with smart electric vehicle charging, centralises control over essential energy infrastructure. SolarPower Europe stated that battery storage is helping integrate growing volumes of renewable energy, strengthen energy security and improve power system resilience across Europe. It added that storage is instrumental to strengthening Europe’s resilience, competitiveness and energy sovereignty.
The Real Cost of Fortress Europe's Energy
The UK's Department of Energy Security and Net Zero refused to comment on concerns about blackouts from the battery boom. Instead, a spokesperson provided a statement focusing on "security of supply" and "value for money for consumers," adding that they "cut VAT on electricity to give families breathing space." Such national-first rhetoric often obscures the global implications of Europe's energy policies, particularly for those displaced by climate chaos.
Beatrice Petrovich, a senior energy analyst at Ember, highlighted that "clean flexibility is here," with rapid growth in batteries, EV smart charging, and heat pumps able to reduce reliance on gas for grid balancing. Ember found that by 2030, four years from now, utility-scale batteries could deliver short-term flexibility in the EU at 20 per cent lower cost than new gas plants. In the next four years, EU batteries could deliver in a single hour more than 80 per cent of the power that all EU gas power plants combined can generate in the same period.
Europe installed 36 GWh of new BESS in 2025, one year ago, bringing total operational capacity beyond 100 GWh for the first time. This capacity is enough to power roughly 75 million homes. The focus on securing energy for European homes, while necessary, often sidesteps the climate crisis's disproportionate impact on the Global South, which fuels forced migration that Europe then criminalises at its borders.
