Designing Cross-Zonal Balancing Capacity Markets: Potential Benefits, Challenges and Ways Foward

Designing cross-zonal balancing capacity market
Share Article

The increasing complexity of balancing power systems is driven by the rising share of renewable energy and the electrification of mobility and industry, leading to greater uncertainty in real-time generation and demand. In Europe, the integration of power markets and the cross-zonal procurement of ancillary services are anticipated to enhance operational security and economic efficiency, which are critical for system operators. While platforms like MARI and PICASSO are operational, experience with cross-zonal balancing capacity services remains limited, primarily seen in initiatives like the "FCR Cooperation" and a few cross-border efforts in the Nordic region and between Germany and Austria.

This whitepaper examines the benefits and challenges of cross-zonal balancing capacity procurement, covering aspects such as market efficiency, price formation, algorithmic scalability, and IT governance. The discussion draws on N-SIDE's extensive experience in ancillary service procurement, particularly through projects like the Enduring Auction Capability Market Design for NESO and the Co-optimization Roadmap Study for the SDAC and SIDC Market Coupling Steering Committee.
