Rising Curtailment and Negative Prices

The European energy transition is entering a new era where grid flexibility is becoming more critical than ever. In May 2026, an estimated 1.28 TWh of solar generation was curtailed in Germany, and more than 2.4 TWh in Spain, as grids struggled to accommodate abundant renewable output. This abundance of renewable energy during peak generation hours has led to significant price volatility. In 2025, negative-price hours accounted for about 6% of the year in major European markets, with Germany alone recording 573 hours of negative wholesale prices. During extreme heat in summer 2026, Germany's day-ahead electricity prices even spiked to around €210/MWh.

EU Commission Calls for Accelerated Action

Addressing these challenges, European Commission President Ursula von der Leyen highlighted the severe renewable grid connection backlog in her State of the Union address on September 16, 2026. She noted that while Europe installed over 80 GW of new renewable capacity in 2025, six times that amount is still waiting for grid connection. Von der Leyen emphasized the urgent need to invest faster, accelerate grid connections, and aggressively develop energy storage to balance the system.

Technological Responses to Grid Codes

To meet these grid stability challenges, technology providers are innovating. Sungrow recently announced its PowerTitan 3.0, a utility-scale battery storage platform featuring up to 92% round-trip efficiency and integrated grid-forming capabilities. This system is specifically engineered to meet evolving European grid codes that prioritize system stability and dynamic balancing. Meanwhile, regulatory frameworks in countries like Germany are also adapting, with potential new revenue sources including capacity markets and dynamic grid fees to incentivize flexible storage assets.
