Europe’s Clean Electricity Record Reveals a Balancing Gap

The European Union covered 72% of its electricity needs with clean sources last year, managing to insulate prices from a gas-market surge — but Eurelectric’s Power Barometer 2026 warns that the shift is exposing a widening gap in the system’s ability to balance supply.

Between February and August 2026, natural gas prices climbed 88.4%, yet wholesale electricity rose by only 22.8%. Eurelectric credits this decoupling to wind and solar, which together provided 30% of EU generation in 2025 — the first time fossil fuels fell below that mark. Grid carbon intensity also hit a record low of 182g CO₂ per kilowatt-hour.

Gas-fired plants increasingly shoulder the balancing role, switching on more often when renewables are insufficient. That dependency became conspicuous during June’s heatwave: rising cooling demand coincided with weaker wind and hydro output, driving prices sharply higher — especially in Central and Eastern Europe, where limited cross-border flows compounded the pressure.

Battery deployment is already demonstrating measurable impact. Bulgaria expanded its storage capacity substantially, and the country’s wholesale prices — which ran 21% above the EU average in 2024 — had narrowed to just 8.3% above by 2026. Christian Ruby, Eurelectric’s Secretary General, said sustained investment in clean energy, storage and flexibility is essential for curbing the extent to which gas price shocks pass through to electricity costs.

EU-wide storage capacity has reached 64 GW, with batteries accounting for 11.2 GW — well short of the 200 GW target for 2030. Deployment is held back by double taxation, outdated grid-connection rules, fragmented ancillary-services markets across all 27 member states, and grid-connection queue regulations.
