Huawei's iSuperSite showcase, a joint venture with China Mobile Hangzhou and the China Mobile Design Institute in Hangzhou, is located in Herui International Science and Technology Plaza in Hangzhou High-tech Development Zone (Binjiang). The site has been upgraded with the Huawei iSuperSite solution since August of 2021. 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 halves electricity fees and cuts O&M costs by 75%, and reduces carbon emissions by eight tons per year.
