///////////////////////////////////// FINAL WORD Huawei predicts 10 emerging trends in telecom energy in next five years Huawei has released 10 emerging trends in telecom energy in 2025, aiming to provide a reference for operators on site infrastructure construction. 5 G is coming. Telecom networks need to undergo these three significant changes: introduce new spectrums and technologies; a lot of new sites; and mobile Edge Computing (MEC) sinking. At the same time, as 5G is applied to more industries, IT and CT will be further merged and network infrastructure will be shared more. So where will these changes drive telecom energy? Trend 1: Energy digitalisation Key point: 90% of sites worldwide will achieve energy digitalisation. With the advent of 5G, the number of sites increases sharply and O&M becomes more complex. The rising OPEX will consume operators’ profits. Energy digitalisation is crucial to simplifying O&M and reducing site O&M costs. Thanks to digital sensing, control and processing technologies, it is estimated that 90% of sites worldwide will have digitalised energy by 2025, making it possible for operators to build simplified, green and autonomous driving networks. Trend 2: Increasing the adoption of green energy Key point: Adopting green energy promotes energy saving and emission reduction for the sustainable development of the industry. To cope with climate change and achieve the Sustainable Development Goals (SDGs) of the United Nations, many global operators have adopted strategies for saving fuel, lower maintenance, zero diesel generators 84 INTELLIGENTCIO across the entire network, lower carbon emissions and sustainable development. In light of this, the investment in green energy has been continuously increasing. New energy technologies such as PV, wind energy, hydrogen fuel cells and lithium batteries are maturing. Although such technologies require relatively high initial investment, they are gradually becoming favoured by operators for their benefits, such as environmental friendliness, low carbon emissions, maintenance-free and low electricity costs. Trend 3: Replacing lead-acid batteries with lithium batteries Key point: Lead-acid batteries will be replaced by lithium batteries and batteries will be increasingly used as a power source rather than backup energy. As 5G is developing rapidly, the power consumption of sites has doubled. An energy storage system with higher energy density is required. Lithium batteries are a perfect choice. Currently, the cycle life of lithium batteries is five times that of lead-acid batteries and the float charge life of lithium batteries is twice that of lead-acid batteries. The life cycle cost of lithium batteries is lower than that of lead-acid batteries. In the next three years, the price of lithium batteries will be reduced by 30%. It is estimated that the cost of lithium batteries will be roughly the same as that of lead-acid batteries in 2022. In addition, the cycle feature of lithium batteries can be fully utilised. The peak shaving feature can avoid mains capacity expansion and reconstruction and elastic www.intelligentcio.com
