Batteries and demand flexibility are ready to scale across the EU

The EU battery fleet is projected to grow fourfold from 37 GW in 2025 to 178 GW by 2030, significantly reducing the need for gas-based backup. By 2030, utility-scale batteries could provide short-term flexibility at 20% lower cost than new gas peakers. Additionally, the report highlights the role of demand flexibility: by 2030, 50% of electric vehicles (EVs) could use smart charging to absorb 7% of peak wind and solar generation, and 15% of heat pump demand could be shifted to high-renewable periods, reducing peak demand by 3%. The report recommends that policymakers avoid overbuilding gas capacity, set ambitious non-fossil flexibility targets by January 2027, and accelerate smart meter rollout to enable these technologies.

• The EU battery fleet is expected to increase from 37 GW in 2025 to 178 GW by 2030, which would allow batteries to deliver over 80% of the power that all EU gas power plants combined can generate in a single hour by 2030, compared to approximately 20% in 2025.
• Utility-scale batteries are projected to grow nearly tenfold, from 12 GW in 2025 to 107 GW by 2030, with 23 of the 27 EU countries expected to at least double their capacity.
• By 2030, utility-scale batteries are projected to be 20% cheaper than new gas peakers for providing short-term flexibility in the EU. ACER estimates 2030 capital costs at 560 €/kW for a 4-hour battery versus at least 650 €/kW for a new gas peaker (OCGT).
• Behind-the-meter batteries are projected to increase the amount of daily rooftop solar generation shifted from midday peaks to evening hours from 9% in 2025 to 17% by 2030. In Germany, this shift could reach 25% by 2030, as installed capacity rises from 14 GW in 2025 to over 30 GW.
• Electric vehicles (EVs) could make up 16% of the EU road fleet by 2030 (39 million vehicles). If 50% of these are enabled for smart charging, they could absorb approximately 7% of peak wind and utility-scale solar generation.
• Heat pump installations could exceed 40 million by 2030. If 15% of their demand is shifted to periods of high renewable output, EU peak demand could be reduced by about 3%.
• The rollout of smart meters is inconsistent across the EU; while penetration exceeds 90% in Italy, France, and Spain, it remains low in others, such as Germany (5.5% by the end of 2025) and Romania (27%).
