Frankfurt, Germany, 05 December 2023. Today the NGMN Alliance (NGMN) issued the next publication concerning energy efficiency: “Effective Energy Saving Strategies and Best Practices for MNOs” providing the industry with further guidance on technical strategies to mitigate high energy costs.

“For the last 18 months high energy costs have put a renewed focus on technical strategies to reduce and better manage energy consumption as well as to ensure network resilience and stability”, said Arash Ashouriha, Chairman of the NGMN Alliance Board and SVP Group Technology at Deutsche Telekom. “This publication – which builds on our recent network energy efficiency roadmap (Green Future Networks: Network Energy Efficiency Phase 2) – provides MNOs with best practice energy saving and energy management techniques”, he stated.

Laurent Leboucher, Member of the NGMN Alliance Board, Group CTO and SVP Orange Innovation Networks at Orange, said “Saving energy is a must for all MNOs. Orange is proud to work in NGMN on this important topic which has immediate and ongoing relevance for the industry. We look forward to a forthcoming further publication on this topic due in Q1-2024 which will provide longer term guidance including on how Radio Access Network (RAN) sharing is a significant and cost-effective way of saving energy”.

“Sharing energy saving strategies and industry recommendations best illustrates NGMN’s efforts in adding immediate value to the industry whilst at the same time shaping the industry’s future direction through our core programmes”, emphasised Anita Döhler, CEO at NGMN Alliance.

This latest NGMN publication was developed with input from across the industry – with NGMN Partners representing operators, vendors, and research institutes. It provides a short guide to the best practices for operators to reduce and better manage their energy consumption whilst simultaneously maintaining desirable network Quality of Service (QoS) and handling a continuous increase of data traffic volume.  The report makes the following best practice recommendations:

• Accelerate the transition from legacy networks (e.g., 2G and 3G) to more energy efficient technologies (e.g., 4G and 5G) whenever possible.
• Deploy additional 5G/4G spectrum refarmed from 3G to increase network data throughput and capacity, and to keep up with the high data growth experienced during the past years.
• Leverage the capabilities of the latest RAN technologies to achieve higher energy efficiency.
• Implement Intelligent RAN energy saving features to save more energy in both 4G and 5G layers.
• Update RAN sites with state-of-the-art energy efficient RAN equipment and antennas which facilitate all mobile generations, 2G to 5G.
• Replace onsite air-conditioning units with energy efficient cooling.
• Deploy renewable energy sources and battery storage units, which reduce the network dependency by electrical grids.
• Use intelligent energy saving features together with battery storage equipment to further increase the network stability.

In addition, the report notes that the industry needs to work further to address several key areas including reducing base station ‘wake up times’ for extreme deep dormancy features and encouraging planning authorities to streamline and accelerate the approvals processes in relation to deploying renewable energy solutions at or near cell sites.

Frankfurt, Germany, 10 October 2023. Today the NGMN Alliance (NGMN) delivered the next publication: ”Green Future Networks: Network Energy Efficiency Phase 2” providing the industry with key
recommendations and a roadmap for reducing the energy consumption of mobile networks.

“Reducing the energy consumption of mobile networks is an important contributor to our journey to become net-zero and recently it has become a focus of the industry due to increased energy costs,” said Arash Ashouriha, Chairman of the NGMN Alliance Board and SVP Group Technology at Deutsche Telekom. “Since 2020 NGMN has contributed guidance on Green Future Networks. Our continuous efforts at NGMN are an important step in enabling operators and suppliers to identify practical and immediate ways to reduce network energy consumption,” he added.

“Our journey to become net-zero is of utmost importance and reducing the energy footprint of our networks is a crucial step in achieving this goal. By maximizing energy efficiency, utilizing renewable energy sources, and implementing energy management solutions, we can continue to deliver high-quality mobile services while meeting our sustainability targets,” stated Laurent Leboucher, Member of the NGMN Alliance Board, Group CTO and SVP Orange Innovation Networks at Orange.

This latest NGMN publication outlines and prioritises various options available to the industry to increase network energy efficiency. Energy saving approaches are organised into three broad categories and time-horizons: process optimisations – short-term; engineering optimisations – medium-term; and new technologies – long-term. Results highlight that it is possible – in the short-term – to reduce energy consumption by up to 10% by optimally configuring networks using existing power saving features. A table of recommended prioritised energy saving approaches is included in this publication. NGMN continues its work in this important area with further collaborative efforts focusing on energy management, metering and providing recommendations on the long-term energy roadmap for the industry.

“NGMN’s vision is to provide impactful and timely guidance to the industry”, said Anita Doehler, CEO at NGMN Alliance. “With the publication of Network Energy Efficiency Phase 2, we implement that vision. We provide prioritised energy saving recommendations addressing both; the immediate-term and the long-term roles that new processes, energy saving features and technologies will play in minimising the energy consumption of mobile networks,” she added
