SHENZHEN, China, Nov. 15, 2021 /PRNewswire=KYODO JBN/ --

Huawei's iSuperSite showcase, a joint venture with China Mobile Zhejiang and

the China Mobile Design Institute in Hangzhou, has recently been accepted.

The site has been upgraded with the Huawei iSuperSite solution since August of

this year. The original six cabinets were replaced by just one, minimizing grid

power consumption. The site was then selected as a green and energy-saving demo

site by China Mobile Zhejiang as part of its carbon emission reduction

campaign. The upgraded site not only halves electricity fees and cuts O&M costs

by 75%, it also reduces carbon emissions by eight tons per year.

50%+ Savings

Before reconstruction, the site had six cabinets and six separate cooling

systems with individual installation space and power supply systems. However,

this resulted in a large footprint, low power system efficiency, and

significant power consumption.

Following implementation of the Huawei iSuperSite solution, the power supplies,

devices, and batteries from the existing six cabinets have been integrated into

just one. 80% of floor space is reclaimed in this manner, allowing for the

installation of a Huawei iPV power generation system to supply solar energy.

Compared with traditional PV power generation system, Huawei's iPV boasts 20%

more energy yield and electricity cost savings of US$2,000 per year, equivalent

to a carbon emissions reduction of 8 tons. Prior to the upgrade, the site's

annual electricity fee was approximately US$3,500.

The upgraded site echoes the carbon peak and carbon neutrality campaign

launched by China Mobile on July 15 of this year in terms of energy saving,

consumption reduction, and carbon emissions reduction. Regarding the campaign,

China Mobile summed up its future development goals as energy saving, clean

energy, and enablement, and determined the following six paths: build a green

network, promote green energy, build a green supply chain, advocate green

offices, enhance green enablement, and create a green culture.

One Lithium Battery, Two Roles

To ensure that network transmission is not interrupted in the case of incidents

such as lightning strikes and power outages, a communication base station

requires backup battery strings of different sizes.

Huawei iSuperSite replaces lead-acid batteries with CloudLi smart lithium

batteries, doubling the power density and upgrading the traditional backup

power unit to an intelligent energy storage system. More importantly, the AI

intelligent self-staggering feature can store power during off-peak periods and

discharge power during peak hours. The electricity cost savings over the course

of one year may exceed US$1.5 billion if all communication sites in Hangzhou

use this feature (calculated based on the residential electricity price with

the smallest difference between peak and off-peak periods).

In addition, Huawei innovatively achieves intelligent power management through

four functions: intelligent metering, backup power slicing, software-defined,

and power audit to improve management efficiency, accelerate the realization of

carbon emission reduction goals, and reduce maintenance costs.

The intelligent power system also supports remote and intelligent O&M, reducing

O&M costs by 75%, deploying 5G without increasing OPEX, and helping carriers

embark on a sustainable development path involving energy saving, consumption

reduction, and carbon reduction.

The convergence of 5G, cloud computing, edge computing, and AI technologies in

the context of "new infrastructure" has presented a diverse range of

possibilities for digital transformation. Energy, as the cornerstone of a

digital society, will inject momentum into the development of the digital

economy. In the context of China's national goals, which involve reaching a

carbon peak by 2030 and achieving carbon neutrality by 2060, various industries

are about to undergo a broad and profound systematic transformation. Energy

conservation, consumption reduction, and carbon emission reduction are

essential to ensuring sustainable development of the communications industry.

The Huawei iSuperSite solution integrates digital, power electronics, and ICT

technologies, helping carriers to upgrade and reconstruct existing sites while

saving power and space. This solution not only meets the requirements for the

rapid coverage of communications networks in the 5G era, but also minimizes

energy consumption, enabling carriers to achieve their carbon emission goals

and build a green future together.
