This chapter explores the significant shift in the local energy landscape as power systems transition from traditional centralized models to modern, distributed frameworks. Historically, electricity flowed unidirectionally from large power plants to passive consumers, but today’s energy systems are increasingly dynamic and decentralized. The rise of distributed energy resources, such as solar panels, wind turbines, and energy storage, has transformed consumers into active participants, or “prosumers,” who both produce and consume energy. This transition introduces challenges, particularly in adapting existing infrastructure to handle bidirectional power flows and integrating variable renewable energy sources. Enhanced visibility and control in low-voltage distribution networks are essential to managing these complexities. The chapter also addresses the need for resilient energy systems in the face of global challenges like aging infrastructure, market volatility, and climate-related disruptions. Innovative approaches, including digitalization and decentralized energy solutions, are crucial for building resilient, equitable energy systems. The discussion includes the UK’s Future Energy Scenarios (FES) and Distribution Future Energy Scenarios (DFES), which guide planning and investment in the evolving energy landscape. Ultimately, digitalization plays a vital role in enabling real-time monitoring, predictive analytics, and the seamless integration of distributed resources, paving the way for a sustainable and reliable energy future.
