Power giant State Grid is set to announce it has completed two intelligent energy towns in Tianjin, thus becoming the first such Chinese towns in which electricity consumers save cost by 10 percent on average, compared with ordinary industrial and residential towns.
 

The company also unveiled an ambitious target to build more such towns in the city's coastal Binhai New Area and throughout the country, due to its prominent carbon dioxide reduction capacity, which is in line with the country's pledge to eventually peak carbon emissions and achieve carbon neutrality.
 

The company said it has invested heavily in the initiative and taken nearly two years to construct the towns located in the Huifengxi residential area of the Sino-Singapore Tianjin Eco-City and Dazhangzhuang township, a model industrial zone in Beichen district, with a combined area of 14.5 square kilometers and a total population of 72,000.
 

It said it has upgraded power facilities, such as energy and heat storage stations, power networks as well as some projects operating in industrial and residential buildings and even some "zero energy consumption" buildings.
 

"To date, the two towns have seen clean energy cover 90 percent of the total area," said Wang Jianfeng, director of the Internet Department of State Grid Tianjin Electric Power Co.
 

"This clean energy utilization rate could benchmark current high-end intelligent towns in Denmark and Finland. In particular, the electricity power there has accounted for 45 percent of the total end power, 18 percentage points higher than the country's average," he said.
 

In addition, the two new towns in Tianjin have slashed carbon dioxide by 20,600 metric tons annually since 2018, he said.
 

走进天津智慧能源小镇

“洛奇,请开启居家模式”。3月14日,走进位于中新天津生态城的惠风溪智慧能源小镇的“0+小屋”,一句语音指令即可遥控室内顶灯和电动窗帘;一键触摸便可实现对家用电器的远程指挥。这个集智慧能源与绿色建筑于一体的“零能耗”小屋是天津市和国网公司首个零能耗智慧建筑。该建筑采用光伏建筑一体化设计,融合“被动式”建筑和“主动式”能源供应技术,通过“产、储、控、用、节”五方面策略,实现了零能耗的目标。
 

“‘0+小屋’,是中新天津生态城惠风溪智慧能源小镇示范项目之一,‘0’代表着零能耗,‘+’代表模式+、平台+和智慧+。”国网天津滨海供电公司营销部项目负责人贺瑞介绍说,这座零能耗智慧小屋共有调蓄空间、绿色氧吧、零能耗概念空间、智慧家居体验空间和智慧商务体验空间等5个空间,建筑面积135平方米。小屋能量来源主要是由屋顶60块光伏板供给,其装机容量达20.7千瓦。
 

作为“零能耗”小屋的“能控中心”,多端口能量路由器通过对电网、光伏、储能以及家用电器之间的能量传输进行智能控制,并依托能耗建筑运行管理系统自动将室内用能场景切换至智能、节能、舒适和个性等不同运行模式,保证了建筑全天候能量的自给自足,真正实现了精细化管理和零能耗运行。
