At the Mobile World Congress (MWC) 2023 held in Barcelona, the world's largest 
and most influential event for the connectivity industry, Bob He, President of 
Huawei Data Center Facility and Critical Power Product Line, launched the 
next-generation energy solutions for the ICT sector on February 27. These 
solutions are designed to assist operators worldwide in building simple, green, 
and intelligent networks.

Intelligent Site Power: A Key Enabler for Green and Low-Carbon Network

Traditional energy solutions for telecom sites typically result in a high total 
cost of ownership (TCO) and contribute significantly to network carbon 
emissions. In an effort to assist telecom operators in building green sites and 
achieving their carbon neutrality goals, Huawei has introduced the concept of 
'Site Power Low-Carbon Target Network'. This innovative solution integrates 
power electronics and digital technologies to build sites that offer 
'Intelligent Simplicity', 'Intelligent Green', and 'Intelligent Saving'.

Intelligent Simplicity: By changing the site structure from rooms to cabinets 
or from cabinets to poles, Huawei's solution simplifies 4G/5G deployment and 
improves site energy efficiency (SEE) from 60% to 97%.

Huawei's 12kW Blade Power System can be mounted on poles, reducing the system's 
footprint from 1 square meter to 0. It takes only 2 hours to deploy. The system 
utilizes natural heat dissipation to achieve up to 97% SEE.

Intelligent Green: By utilizing multi-energy intelligent scheduling, we can 
lower the levelized cost of energy (LCOE) while increasing the proportion of 
green power used for sites. Huawei's iSolar 2.0 solution adopts high-voltage 
serial connection architecture and four-in-one solar blade products to make 
green power acquisition easier and reduce engineering costs by 15%. 
Additionally, PV optimizers are used to reduce shading losses and increase 
clean power generation by 20%. The solar+storage intelligent synergy can enable 
the green power utilization rate to reach 100%.

Intelligent Saving: Lithium batteries, which serve as both backup power sources 
and energy storage systems (ESSs), will be widely used at sites. Equipped with 
lithium batteries, telecom sites will increase revenue and reduce expenditure 
by leveraging new applications such as peak staggering and virtual power plants 
(VPPs). Huawei's Cyclic CloudLi solution, known as 200Ah@5U, offers a 50% 
improvement in capacity over the previous-generation product, thereby 
maximizing energy storage value.

Smart DC, Building the Green Future

Data centers serve as the foundation of the digital world but consume 
considerable amounts of energy. Huawei introduces end-to-end green data center 
solutions for large, small and medium-sized data centers to help operators 
advance their carbon neutrality goals.

Power System: As a preferred solution for power supply systems in large data 
centers, Huawei PowerPOD 3.0 features footprint-saving, power-saving, 
time-saving, and worry-free. It reduces the number of cabinets from 21 to 10 
and saves 50% of floor space. Additionally, the S-ECO mode improves the 
efficiency to 98.4% from the previous 95.4%. By using prefabricated busbars 
instead of cables, delivery time is reduced from 2 months to 2 weeks. Besides, 
the iPower intelligent feature enables predictive maintenance, transforming 
reactive maintenance into proactive maintenance.

Cooling System: EHU, an indirect evaporative cooling solution, uses polymer 
heat exchangers and EC fans to maximize the use of free cooling sources. It 
reduces multiple heat exchanges to one-time heat exchange, improving cooling 
efficiency. Compared with traditional chilled water solutions, the EHU solution 
achieves a power usage effectiveness (PUE) as low as 1.15 and water usage 
effectiveness (WUE) as low as 0.37 in an Ireland data center project, and 
reduces the number of operation and maintenance items by 60%. By using modular 
and prefabricated architecture, the cooling system integrates multiple 
components into one container, shortening the delivery time by 50%.

In the future, Huawei will continue to innovate and cooperate with global 
partners to help operators build green and low-carbon networks amid the global 
transition to carbon neutrality.
