Company/Organization Profile

The State Grid Jia Wang District Power Supply Company in Xuzhou was originally established as the "Jia Wang Power Supply Bureau" in 1994. It was restructured into the "Jia Wang Power Supply Company" in 2004, then into the "Jia Wang Power Supply Branch" in 2010. In 2020, with the support of provincial and municipal companies, it was renamed the "State Grid Jia Wang District Power Supply Company," serving as a county-level subsidiary under the municipal company. The company is responsible for providing power supply services to high and low voltage users in the Jia Wang area, as well as the operation and maintenance of 10 kV and below distribution networks. The Jia Wang company comprises five functional departments, two business units (institutions), oversees seven power supply offices, and manages the Ziquan Company, which consists of personnel transferred from mining operations.

项目背景

徐州贾汪区作为典型的资源型城区，长期依托煤炭产业发展，形成了高耗能、高排放的发展模式，区域生态环境承压、能源结构转型滞后，是资源型城市低碳更新的典型区域。在城市绿色转型发展进程中，公共空间尤其是高校校园空间是城市微更新、低碳场景落地的核心载体。高校空间覆盖面广、功能场景多元、人员集聚度高，通过精细化空间微改造，打造生态友好、低碳可视的绿色用能与生活场景，能够有效提升校园空间环境品质、强化生态服务功能，形成可复制、可推广的城市低碳转型样板。

Project Overview

As a typical resource-dependent urban district, Jiawang District in Xuzhou has long relied on the coal industry, forming a high-energy-consuming and high-emission development model. The regional ecological environment faces pressure, and the energy structure transformation lags behind, making it a typical area for low-carbon renewal in resource-based cities. In the process of urban green and low-carbon transformation, public spaces—especially university campuses—serve as core carriers for micro-renovation and the implementation of low-carbon scenarios. With extensive coverage, diverse functional scenarios, and high population density, university spaces can effectively enhance environmental quality and strengthen ecological services through refined micro-renovation. This approach creates replicable and scalable models for urban low-carbon transformation.

Project Implementation

This project is led by State Grid Jiawang District Power Supply Company in Xuzhou City, and is jointly implemented by the School of Science and Technology of Jiangsu Normal University, Tsinghua University, and Pinggao Group. The project adheres to the concept of "micro renovation and quality improvement", and does not engage in large-scale demolition and construction. In response to the problems of high carbon energy consumption, insufficient ecological quality, extensive energy consumption control, and limited low-carbon service radiation in the campus, the fine micro renovation of three types of campus spaces, namely energy, control, and resources, has been implemented in three major scenarios: low-carbon heating, intelligent control, and load based virtual power plants, effectively promoting the low-carbon upgrading of the campus. The implementation of each link is as follows. 1、 Energy space transformation: solving the problems of high carbon, low efficiency, and disorderly space in traditional heating In response to the problems of high pollution, disorderly equipment, damage to campus ecology, and waste of idle space caused by traditional coal-fired gas heating, the project adopts a fully electric clean heating solution. Based on the idle and logistics space of the campus, three fully electric energy stations will be built, equipped with electric thermal storage boilers and solar collection systems, to replace traditional decentralized high carbon equipment. Under the overall planning of State Grid Jiawang Power Supply Company, the School of Science and Technology provides existing sites, and Pinggao Group provides equipment and technical support. Through local spatial micro renovation, nearly zero emissions of heating are achieved, and energy-saving facilities are integrated with campus landscapes to create a visual low-carbon scene. 2、 Space control renovation: solving the problems of extensive energy control, invisible energy consumption, and low comfort in campus In response to the problems of extensive control of public energy use on campus, opaque energy consumption data, low heating efficiency, and unreleased energy-saving potential, the project has implemented intelligent transformation of 346 landscape lighting and 122 air conditioning loads, and built a comprehensive intelligent energy control platform. Tsinghua University provides digital technology support, the power supply company is responsible for platform construction and implementation, and the school cooperates with on-site renovation and implementation. Real time monitoring of energy consumption across all categories is achieved through the Internet of Things and intelligent metering technology. Innovative implementation of valley electricity storage and flat electricity replenishment modes is promoted to quickly improve heating comfort, achieve load response in seconds, and fully tap into the energy-saving potential of public spaces. 3、 Resource space transformation: solving the problems of limited campus, scattered energy resources, and insufficient service capabilities in low-carbon scenarios In response to the limitations of low-carbon campus scenarios, the dispersion of regional load resources, and the high pressure of power grid peak regulation, the project relies on the campus smart energy consumption foundation to innovatively create Xuzhou's first load type virtual power plant. Led by the power supply company, resources are coordinated and linked with multiple entities such as local authorities, commerce, and industry. Through lightweight resource integration and digital linkage upgrading, there is no need to add new infrastructure, and 62000 kilowatts of adjustable load are aggregated. The campus low-carbon demonstration space is upgraded to a regional energy service carrier, effectively helping the power grid peak shaving and valley filling, and expanding the radiation range of low-carbon ecological services. 4、 Overall implementation effectiveness of the project All parties involved in this project have clear division of labor and efficient collaboration, using lightweight and micro renovation to solve the pain points of high carbon heating in southern areas without centralized heating, forming a replicable zero carbon heating model. At the same time, relying on the existing space to improve quality and upgrade, the campus public space will transform from a single living function to a diversified function of low-carbon services, power grid supply guarantee, and ecological efficiency enhancement, effectively reducing regional carbon emissions and improving the green adaptation level of regional energy.

Project Outcome

1、Creating a zero carbon heating model through campus micro renovation, achieving replicable and promotable green scenes This project is the first comprehensive energy demonstration project in Jiawang District that relies on micro renovation of public spaces to achieve clean heating throughout the entire area. It breaks away from the traditional transformation mode of large-scale projects and construction, and updates campus space with refinement and lightweighting to solve the problem of high carbon heating in areas without centralized heating in the south. Through small-scale space renovation and scenario based low-carbon creation, an eco-friendly, experiential, and visually perceptible campus green living scene has been constructed, providing a new model of "micro renovation and large efficiency improvement" for low-carbon renewal of universities, large parks, and densely populated public spaces across the country. 2、Pioneering load based virtual power plants through spatial function upgrades, expanding the boundaries of ecological services Based on the results of the campus smart space micro renovation, we innovatively create Xuzhou's first "load type" virtual power plant. Through spatial function iteration and resource integration and upgrading, there is no need to add new generator sets or expand physical space. Only by improving the quality of existing space, we can achieve intensive utilization of regional load resources. The project aggregates 62000 kilowatts of active demand response load, saving a large amount of power grid infrastructure investment, significantly reducing regional carbon emissions, and achieving a leap in public space from a single living function to low-carbon services, power grid supply guarantee, and ecological efficiency enhancement.
