Although Europe is decarbonising fast, clean electricity is not always available when demand occurs. Europe’s challenge is now integrating renewable power so it can be used when and where it is needed. High-impact corporate buying unlocks this value by aligning demand with clean supply, enabling cheaper electricity, strengthening competitiveness, and driving investment in grids, flexibility, and storage.
Europe’s energy transition has rapidly expanded renewable generation. Wind and solar now provide the biggest share of electricity, but their variability exposes a new challenge: clean electricity is not always available when demand occurs. Addressing this mismatch is increasingly central to system reliability, energy security, and affordability. A decarbonised power system requires investment in flexibility, infrastructure, and clean firm capacity that can deliver renewable power regardless of weather conditions.
“Under current rules, companies can claim 100% renewable electricity even while still relying on fossil fuels during peak price, low-renewable hours,” says Killian, Executive Director of the independent non-profit EnergyTag. As electrification accelerates across industry, transport and digital infrastructure, further prompted by the EU’s upcoming Electrification Action Plan, these hourly gaps increasingly matter for both costs and emissions. A granular matching approach addresses this directly.
Visibility is increasingly important as grid congestion, curtailment and price volatility rise. Across Europe, negative power prices exceeded 9,000 hours in 2025, while Germany, France and the Netherlands alone saw more than 3800 GWh of curtailment. Earlier in 2023, nearly 30 terawatt-hours of generation was curtailed across only six countries in Europe, representing a cost to the economy of almost EUR 9 billion.
Storage and flexibility are central to ensuring the European system can absorb and deliver renewable power efficiently and reliably while maintaining affordability. In the European Union, battery storage capacity is expected to reach 46 GW by 2030 and more than 220 GW by 2040 to provide the flexibility required for a high-renewables system. Overall system flexibility requirements are also expected to quadruple by 2050.
Hourly clean energy procurement creates commercial pathways for emerging technologies, such as hybrid PPAs which combine generation and storage and as well as long-duration energy storage solutions.
High-impact renewable energy sourcing does not just enhance energy security through homegrown clean power, it also improves investment signals for European grids, flexibility mechanisms and supports innovation in clean firm power. As electrification accelerates and competition for cheap clean electricity intensifies, the companies and regions that adopt granular energy strategies early are likely to benefit from more resilient power systems and stronger industrial competitiveness.
