Local flexibility markets in Europe: A critical review of market designs, operational maturity and stakeholder perspectives

Local Flexibility Markets (LFMs) are gaining importance across Europe as a potential solution to emerging challenges in the management of distribution networks. Driven by European Union directives on electricity market design, LFMs aim to enable distribution system operators to procure ancillary services from distributed energy resources through transparent and economically efficient mechanisms. This study offers a comprehensive analysis of the designs and current implementation stages of LFMs, combining a systematic literature review with an in-depth assessment of selected European cases and structured interviews with key stakeholders. The literature analysis highlights current research trends, methodological approaches, and future developments. The case analysis covers various European countries, including nations with mature LFMs, such as Great Britain, as well as those where LFMs are still in the early stages of development, such as Italy. Specifically, it provides detailed insights into ancillary services definitions, technical and market requirements, remuneration schemes, baseline calculation methodologies, and observed market outcomes. Interviews with distribution system operators, balancing service providers, and market platform operators enrich the analysis by revealing practical perspectives on the benefits and challenges of LFMs. The findings indicate that regulatory fragmentation, lack of standardized flexibility products, and inadequate communication and automation infrastructure are major barriers to broader deployment. Unlocking the full potential of LFMs will require coordinated regulatory action at the European level and targeted investments in essential enabling technologies.
