Energy Storage Regulatory Frameworks | Country Case Studies
ESMAP’s Energy Storage Regulatory Frameworks: Country Case Studies examines policies, market structures, and financial mechanisms supporting battery energy storage deployment in Australia, Germany, Great Britain, Ireland, Italy, Japan, Türkiye, and Ukraine. The report identifies regulatory approaches and practical lessons for expanding storage, strengthening grid flexibility, and integrating renewable energy.
Key Findings
- Regulatory clarity enables investment. Recognizing energy storage as a distinct asset class and removing discriminatory network charges can improve project economics and market access.
- Multiple revenue streams strengthen project viability. Revenue stacking across energy arbitrage, ancillary services, and capacity mechanisms helps storage projects build sustainable business models.
- Long-term support reduces investment risk. Long-term procurement mechanisms, competitive auctions, long-term contracts, targeted incentives, and revenue support schemes can improve financing prospects where short-term market revenues are insufficient.
- Market access expands storage opportunities. Enabling aggregation, virtual power plants, and participation across electricity markets allows storage resources of different sizes to provide valuable grid services.
- Grid connection delays and revenue uncertainty remain major barriers. Congestion, lengthy interconnection processes, evolving market rules, and volatile revenues can delay projects and undermine investment.
- Policy and market reforms are essential for scaling deployment. Streamlined grid connections, technology-neutral market participation, appropriate compensation mechanisms, and predictable long-term support can accelerate storage deployment.
The findings offer practical guidance for policymakers and regulators seeking to unlock energy storage’s potential, support renewable energy integration, and build more flexible and reliable electricity systems.
