As distribution system operators (DSOs) gain experience with local flexibility markets, the focus is increasingly shifting from pilot projects to stable, scalable and enduring solutions. This session will examine what it takes to move from experimental local flexibility schemes to robust markets that can be reliably integrated into system operation and investment planning. The discussion will address regulatory readiness, market design choices, standardization, coordination with other system operators and the conditions needed to provide long-term security for flexibility providers. By bringing together DSOs, policymakers, market actors and technology providers, the event aims to identify practical pathways towards sustainable local flexibility markets that support a resilient and decarbonized electricity system.
