This Ecosystem Resource Publication examines how the O‑RAN framework enables Network Energy Saving (NES) through a range of intelligent and flexible energy-efficiency features. It covers key use cases, including energy optimization across different network components, and discusses practical implementation approaches enabled by O‑RAN’s open architecture, automation capabilities, and data-driven intelligence. The publication also addresses important deployment considerations such as maintaining network performance, adapting to traffic variations, ensuring interoperability, and aligning energy-saving actions with operational objectives. Through representative implementation examples and real-world case studies, the document demonstrates how O‑RAN NES capabilities can help operators reduce energy consumption, lower operational costs, and support sustainability goals while preserving service quality and network reliability.
