This brochure presents the insights gathered as part of the ISGAN WG9 Task, drawn from stakeholder engagements with representatives from Austria, Switzerland, Belgium, Japan, the Republic of Korea, the United Kingdom, and Spain. As energy systems undergo rapid transformation due to increasing electrification and the integration of distributed energy resources, traditional distribution network planning faces new challenges. This document explores how flexible resources, such as demand response, battery storage, and advanced grid management strategies, can be effectively incorporated into distribution networks. By analyzing regulatory frameworks, technological advancements, and real-world case studies, the findings aim to support decision-makers in navigating the ever-changing landscape of grid planning and ensuring resilient, efficient, and future-proof electricity networks. This publication was prepared for the International Smart Grid Action Network (ISGAN) by its Working Group 9. ISGAN is organized as the Implementing Agreement for a Co-operative Programme on Smart Grids (ISGAN) and operates under a framework created by the International Energy Agency (IEA). The views, findings and opinions expressed herein do not necessarily state or reflect those of any of ISGAN’s participants, any of their sponsoring governments or organizations, the IEA Secretariat, or any of its member countries.
