This project is located in Xiaogang Village, Fengyang County, Chuzhou City, Anhui Province, China.
This project is the first attempt of Xiaogang Village, the “village leading China’s rural reform”, and State Power Investment Corporation Limited (SPIC), which is the world’s largest clean energy power generation enterprise, to achieve rural energy transformation and low carbon emission. It is the first modern and green village integrated smart energy project built by the SPIC, and is also one of the first batch of modern and green village integrated smart energy projects in China.
This project fully utilizes the existing resources of Xiaogang Village, takes into account the characteristics of scattered rural resources and energy consumption, maintains local characteristics, plans multiple energy elements, and realizes the development of low-carbon ecological energy in Xiaogang Village from the aspects of developing green industries, energy conservation and emission reduction, developing clean energy, green travel, and cultivating low-carbon lifestyles.
In addition, the project effectively connects the energy network, government affairs network, and community network through the “Tianshu-1” integrated smart energy management and service platform – a all-new digital system, fusing with the information regarding government affairs, agricultural affairs, business, tourism, health care, and education and training to every family and organization in Xiaogang Village instantaneously and accurately.
The specific technical schemes involved in this project are as follows:
1.Distributed Solar photovoltaic power generation system
The project has been built a solar photovoltaic power generation system with a total capacity of 18.7MW, including complementary agricultural photovoltaics, complementary fishery photovoltaics , household photovoltaics. With an annual electricity generation capacity of 21.774 million kWh,Replacing traditional fossil fuels and reduces carbon emissions.
2.Green electric transportation system
The project has built two 120kW DC charger piles with a design life of 10 years in the solar photovoltaic shed.

Replacing gasoline buses, and promoting green transportation.
3.Geothermal pump cooling and heating system
The Geothermal pump cooling and heating systems of the historical museum, the village committee’s office, and the nursing home has been upgraded. The cooling and heating energy source system is a magnetic levitation ground source heat pump, which provides cooling in summer and heating in winter. The simultaneity usage coefficient of the air conditioning system is 0.9, the cooling load is 450kW, and the heat load is 318kW,replacing traditional electric air conditioning, improves energy utilization efficiency.
4.Advanced DC demonstration system
A 5kW ground photovoltaic system has been built in the open area. It is connected to the energy router through buried cables, and DC power is supplied to advanced energy technology through supporting DC air conditioning, DC purifiers, DC water dispensers, DC hot water kettles, and other DC electrical equipment, replacing AC household appliances, and improving photovoltaic utilization efficiency.
5.Straw comprehensive utilization system
The project plans to build a black biomass pellet production plant with an annual capacity of 15,000 tons and a straw processing capacity of 4T/h. With high quality and slightly higher fuel cost, black pellet fuels are more cost effective than natural gas.
6.Energy management system
The development of Tianshu-1 integrated smart energy control and service platform system helps to realize centralized monitoring and management of PV modules, energy storage facilities, charging piles, heating and cooling loads and village ’ s power distribution system in different locations. Enabled by data sharing and analysis in the integrated smart energy project, this system has achieved smart, integrated, remote and visualized management of energy. Through regional performance calculation and analysis, it realizes overall integration and flexible management of energy in the village, improves the comprehensive energy utilization rate and reduces carbon emissions.
7.Three networks integration”Smart management system
The integrated smart energy control enabled by Tianshu-1 and integrated smart management provided by the service platform integrate smart elements such as big data, cloud computing and Internet of Things into such key areas as government affairs and people ’ s livelihood in Xiaogang Village. Government service network and community network based on the energy network platform are established to realize the “three networks integration”. The self-developed Tianshu-1 includes 49 applications in nine categories and has passed the CNAS certification.
Through the implementation of this project, the specific results are as follows:
1.Beautiful countryside: Xiaogang Village integrated smart energy project 100% meets and is superior to the China and Anhui provincial standards for the construction of beautiful countryside.
2.Energy Saving: With the installation of Geothermal pump system, cooling and heating with clean energy are fully realized, saving about 75% of electricity cost.
3.Green transportation: By implementing photovoltaics, energy storage, bus charging stations, and electric bicycle charging stations, the advantages of green, energy-saving, pollution reduction, and carbon reduction in transportation can be fully utilized.
4.Carbon neutralization: The annual power generation of clean energy is 21.7774 million kilowatt hours, achieving 100% clean electricity substitution in the entire village.
5.Environmental benefits: A reduction of 16,315 tons/year in carbon dioxide emissions, 480 tons/year in SO2 emissions, and 240 tons/year in NOX emissions.
6.Smart brain: “Tianshu-1” integrated smart energy management and service platform is created, which integrates energy, government affairs, agriculture, education, health care, and tourism, so as to realize centralized monitoring and management of solar photovoltaic, energy storage, charging piles, cooling and heat load, and within-village power distribution system; and through data sharing and analysis and regional-level performance calculation and analysis within the integrated smart energy project, the integration and dynamic smart management of energy and life in the village can be realized, which raises the comprehensive energy utilization rate of project, reduces carbon emissions, and improves villagers’ quality of life and increases tourist satisfaction.

What is the policy, vision, or objective of the town? Please specify the actual goal and its metrics, if applicable.
Xiaogang once created a "historical height" for China’s rural reform, but currently, the four elements of land, labor, funds, and technology in rural areas are in a "net outflow" state. Against the backdrop of diversified rural development in China, it is still difficult for Xiaogang to once again create a "new height" for China’s rural reform process. Xiaogang should follow the central government’s requirements proposed, respect objective development conditions, base itself on itself, fully utilize the advantages of ecological and tourism resources, and achieve peaceful development. According to the requirement put forward by provincial Secretary during his inspection of Xiaogang Village that "the development of Xiaogang Village must establish a new benchmark for development, and establish a new benchmark for reform and innovation throughout the province and the country", it is suggested that this new benchmark be positioned as a "National Demonstration Village for Beautiful Countryside". The development positioning of Xiaogang Village is determined as follows:
Led by modern agriculture and tourism services, aimed to build a beautiful rural demonstration village that is characterized by economic prosperity, prosperous living, beautiful environment, and democratic harmony.
