Technical Aspects of Nodal Pricing

The report examines the technical and operational challenges of implementing nodal pricing in Europe, contrasting the European model of separated energy and transmission markets with the US Independent System Operator (ISO) model. It highlights conflicts between market flexibility and transmission system operator (TSO) security needs, the potential for integrated energy and reserve markets to increase flexibility, and the technical uncertainties surrounding the EU Target Model's flow-based approach to congestion management.

• Integrating intermittent generation creates a conflict between market participants who want short-notice flexibility for production changes and TSOs who require sufficient time to analyze and adjust for network constraints.
• The separation of energy and reserve markets in Europe can lead to inefficient production decisions for generators with small portfolios who struggle to align volume and time-slots across different markets.
• In the US PJM region, the integration of transparent energy and reserve markets has enabled demand flexibility to replace fossil generation as a primary source of system flexibility, with 14 GW of demand contracted for reserve and response, representing 7% of installed capacity.
• The US PJM ISO's use of location-specific information and nodal pricing allowed it to reduce operational margins from approximately 20% of capacity 15 years ago to 1% today, whereas some European Interconnectors maintain reliability margins around 50%.
• The EU Target Model's proposed flow-based approach to calculating transmission capacity faces technical uncertainties regarding the definition of critical network elements, the accuracy of DC approximations of AC networks, and the reliability of generation shift keys (GSKs).
• US Independent System Operators (ISOs) serve as intermediate institutions that integrate short-term market and system perspectives, allowing transmission owners to retain asset control while removing the risks associated with system operation.
• Shadow prices resulting from congestion management based on the physical grid can provide quantitative data to inform network expansion decisions and model future requirements.
