Energy management for mobile network operators (MNOs) is a critical area for addressing challenges like fluctuating energy costs, integrating renewable energy, and enhancing sustainability, as detailed in this NGMN report. The report outlines key strategic paths and provides recommendations based on global energy market trends.

Executive Summary

Operators must manage energy costs and carbon emissions while meeting user demands. Key opportunities include leveraging energy flexibility markets through strategies like grid first, site level (using renewables and batteries), and network level (aggregating resources for wholesale markets). Challenges include coordinating forecasting, ensuring regulatory compliance, and integrating AI for optimization. Recommendations emphasize aligning energy strategies with the maturity of variable renewable energy (VRE) integration in specific countries.

Introduction

The NGMN Green Future Networks Programme focuses on telecom energy efficiency and sustainable operations. This publication explores energy management options, including multi-source management, energy storage, and network-level coordination, to help operators reduce costs and create new services.

Challenges and Opportunities

Operators face hurdles such as reducing reliance on grid power, managing volatile energy prices, and integrating renewables. However, opportunities exist in adopting flexible energy management, optimizing energy use for sustainability, and participating in markets to generate revenue.

Energy Management Strategies

Three primary strategic paths are identified:

• Grid First: Focuses on cost-effective grid energy procurement through contracts, PPAs, or investments.
• Site Level: Manages on-site energy sources, including batteries and VRE, to minimize costs and emissions.
• Network Level: Aggregates distributed resources to participate in energy markets, offering ancillary services or energy arbitrage.

Best Practices and Recommendations

1. VRE Integration Planning: Operators should consider their country's VRE phase when choosing strategies; focus on grid reliance only in advanced VRE markets.
2. Site-Level Management: Energy strategies must account for available sources (grid, local renewables, battery), traffic load, and regulatory requirements for service continuity.
3. Network and AI Role: AI and automation are essential for efficient energy management, with MNOs ensuring data integrity and demonstrating system reliability to regulators.
4. Energy Flexibility: MNOs must standardize regulations and collaborate with energy industries to harmonize markets for better VRE integration and demand response services.

The NGMN Alliance urges operators to prioritize these recommendations to balance cost savings with sustainability and operational resilience.
