CC BY 4.0. Abstract This policy brief, developed under the International Energy Agency’s Digital Demand-Driven Electricity Networks (3DEN) Initiative, examines the value of demand flexibility as a core component of modern electricity systems, with a strong emphasis on its role in improving energy efficiency. As electricity demand grows and power systems become more electrified, decentralised and renewable-rich, managing when and how electricity is used is increasingly as important as expanding supply. The brief sets out a clear framework for understanding demand flexibility and highlights its contribution to an efficiency-first approach to power system planning and operation. By shifting or adjusting electricity use in response to system conditions, demand flexibility improves the utilisation of existing generation and network assets, reduces peak stress, lowers losses and curtailment, and supports more efficient integration of clean energy. It also delivers wider benefits, including enhanced energy security, lower system and consumer costs, and reduced emissions, when appropriately enabled and valued. The policy brief identifies key trends driving the need for flexibility, the main barriers limiting its uptake, and priority areas for policy action. It concludes that integrating demand flexibility alongside energy efficiency within regulatory, market and planning frameworks is essential to delivering secure, affordable and efficient power systems, while maximising the value of existing and future investments.
