Summary of the European Electricity Market Reform Proposal

Executive Summary

The proposed reform of the European electricity market design maintains crucial elements of the existing system to ensure continued efficient operation. The key goal is to address the shortcomings exposed during the 2022 energy crisis, particularly in fairness, investment incentives, and operational efficiency. The reform focuses on long-term contracts, consumer protection, and demand-side flexibility. A core finding is that the current market design relies on marginal pricing, which proved effective during the crisis but requires adjustments to ensure it remains efficient amid increasing renewable integration.

Key Findings

• Operational Efficiency: The market continues to function during crises, but investment incentives are weak. Expanding renewables and transmission capacities is critical.
• Fairness: Consumers bore the brunt of price spikes during the crisis. Long-term contracts like Contracts for Difference (CfDs) and Power Purchase Agreements (PPAs) aim to protect consumers while shielding generators from volatility.
• Investment: Current reforms lack clear long-term signals. CfDs and PPAs should be designed to preserve short-term market incentives.

Market Instruments and Design Details

1. Contracts for Difference (CfDs):
   • Effective for hedging but must avoid distorting short-term markets. Poorly designed CfDs can eliminate operational incentives.
2. Power Purchase Agreements (PPAs):
   • Voluntary contracts should minimize moral hazard and restrict to new renewable assets to avoid undermining market signals.
3. Peak Shaving and Flexibility Mechanisms:
   • Not justified as they introduce unnecessary complexity. Existing short-term markets provide better incentives.
4. Energy Sharing:
   • Useful for local integration of renewables but risks centralizing costs and benefits.

Recommendations

1. Avoid Moral Hazard:
   • Long-term contracts should not stifle short-term price signals. CfDs and PPAs must align with market mechanisms.
2. Keep Short-Term Markets Intact:
   • Interventions like peak shaving should not create duplicate markets or distort flexibility incentives.
3. Address Network Barriers:
   • Power-based network tariffs hinder demand-side flexibility. Reforms should include time-variable network tariffs to incentivize flexibility.
4. Prioritize Transmission Expansion: Cross-border capacity increases efficiency and reduces costs.
5. Impact Assessment: Future reforms must include thorough quantitative analysis to balance distributional and efficiency goals.

Conclusion

The reform must balance short-term stability and long-term investment signals. Policymakers should focus on tools that preserve market efficiency while advancing decarbonization. The European electricity market requires careful calibration to avoid unintended consequences like moral hazard or market distortions.
