The clear and refreshing wind brings joy to all things, which is the best scenery of the year. From August 25 to 28, entrepreneurs and representatives of the multinational companys who participated in the international cooperation and communication meeting of Yancheng Zero Carbon Industrial Park, visited Yancheng Dafeng Deer Nature Reserve, Dongtai Tiaozi Ni Wetland, and Yining Energy Park, and embarked on a field visit and inspection tour, experienced the beauty of Yancheng's ecology and feeling the green transformation.

"This industrial park is really good, with complete infrastructure and advanced technology. You can feel elements such as 'green, low-carbon, and smart' everywhere in the park," exclaimed a foreign journalist who was visiting Yining Energy Science and Technology Innovation Industrial Park on August 28.

The park is an industrial agglomeration base and intelligent warehousing base for State Grid Yancheng Power Supply Company and Jiangsu Yining Energy Industry Group Co., Ltd. A total of 1.659 MW photovoltaic panels have been installed in the park, which can achieve an annual power generation of about 1.8 million kWh. The park has built a demonstration application project of 'regional source grid load storage integration' AC and DC microgrid, consisting of more than 20 smart system projects. Using the energy carbon big data model, a micro carbon smart energy control platform has been constructed.

By integrating clean energy sources such as wind, solar, and geothermal, it has been able to regulate a new energy installed capacity of 1.65 megawatts, and has cumulatively generated over 1.4156 million kilowatt hours of electricity, reducing carbon emissions by 1967.31 tons.

The "Micro Carbon Smart Energy" concept not only builds the park's own microgrid system, but also provides a good reference for the further development of green energy industry in Yancheng.

In 2023, Yineng Group successfully achieved the first case expansion and replication in the government built Sheyang Zero Carbon Industrial Park, which has built and operated an "energy carbon" dual control management platform, clarifying the green power supply structure of the park, conducting full factor carbon emission accounting, and building a safe, controllable, efficient, and diversified energy storage "zero carbon" ecosystem. The industrial park is expected to be officially put into operation by the end of September this year.

In addition, entrusted by the government of Yancheng, an industrial park have been designated as the core area, and a low and zero carbon demonstration island have been expanded outward. Multiple business formats such as zero carbon park, office, industry, residential and living facilities have been planned and constructed.

On January 10, Yineng Group. and Guangzhou Saibao Certification Center Service Co., Ltd. signed strategic partnership agreement. Nowadays, Yineng Group can act as an authoritative third-party organization to assist enterprises in carbon emission measurement and grant carbon neutrality certificates.

“We will continue to play a key role as a third-party certification body for carbon neutrality, providing strong support for the sustainable development of social enterprises, promoting the green transformation of the entire society. "said Wang Guoping, the person in charge of Yineng Group.

Basking in the wind, the green energy surges. Driving along the coastline of Yancheng, clusters of wind turbines rotate with the wind, and the beautiful scenery resources are gradually becoming green energy for development.

In the first quarter of this year, the cumulative power generation of new energy in Yancheng was 8.99 billion kilowatt hours, a year-on-year increase of 21.2 percent, accounting for 29.2 percent of the province's new energy power generation and 75.1 percent of Yancheng's total social electricity consumption. It became the first city in East China to have new energy power generation accounting for three-quarters of the total social electricity consumption.

State Grid Yancheng Power Supply Company continuously promotes the transformation and upgrading of the backbone network and the coordinated development of main distribution and micro systems, enhancing the resilience and new energy consumption level of the backbone network.

In March of this year, the "Distributed New Energy Resource Aggregation Platform" led by State Grid Yancheng Power Supply Company was officially launched.It provides accurate load data and the accuracy of busbar load forecasting has been improved from 92 percent to 96 percent.

In order to ensure the efficient consumption of massive new energy electricity, Yancheng Power Supply Company is accelerating the construction, in order to meet the large-scale new energy full consumption demand in the region and simultaneously achieve efficient transmission of surplus electricity. It is expected that after completion, the annual new energy power generation in Yancheng area will increase by over 80 billion kilowatt hours.

However, the seasonal intermittency and volatility of new energy sources such as wind power and photovoltaics have brought new challenges to the power grid. On July 12, the largest new energy storage project in the province, the Yuanjing Sheyang 250000 kW/500000 kWh energy storage power station, was connected to the grid. So far, all 8 new energy storage projects on the grid side included in the power system planning in Yancheng area have been put into operation, with a total scale of 1.51 million kilowatts/3.02 million kilowatt hours, ranking first in the province.

The 500 kV Heqi substation connected to this project is the intersection of 700000 kW offshore wind power transmission. More than one-third of the green electricity can be stored inthe Yuanjing Sheyang Energy Storage Station. It is expected that the annual peak shaving and valley filling electricity can reach about 240 million kWh, which will effectively improve the power supply and new energy consumption capacity.

Yancheng is currently promoting a 400000 kW grid side energy storage projects that has been included in the plan.After putting into operation by 2025, the scale of the regional energy storage cluster will reach 1.91 million kW/4.12 million kWh, "said Cheng Shidong, staff of the Development Department of State Grid Yancheng Power Supply Company.

On July 26, 2019, at the 46th UNESCO World Heritage Committee Meeting held in New Delhi, the Chinese Yellow (Bohai) Sea Migratory Bird Habitat declared by China successfully passed the review of the Heritage Committee and were successfully included in the The World Heritage List.

Wetland ecological restoration work should not only maintain the original appearance of wetlands, but also serve local economic development. State Grid Yancheng Power Supply Company has been involved since 2017, carrying out a series of work and gradually exploring a model of harmonious coexistence between power grid operation and wetland protection.

The Chuanshuiwan Coastal Wetland Restoration Project, is the first ecological restoration project carried out in a coastal heritage site in China. Among them, the relocation of 147 livestock farmers covering an area of 18000 acres is the top priority of the entire wetland renovation. State Grid Yancheng Power Supply Company actively contacted the local government and formulated a detailed plan for pole and line relocation based on the specific situation of the wetland, including the scope and methods of pole and line relocation. At the same time, it carried out publicity with livestock farmers on the progress of wetland restoration.

There are many similar cases in Yancheng, such as the restoration of the Yellow Sea wetland, the restoration of the Dazong Lake wetland, the restoration of the Jiulongkou wetland, and so on. With the continuous expansion of wetland areas, more and more birds choose to come and inhabit. Nowadays, Yancheng Wetland has 3308 species of living organisms and 442 recorded bird species, accounting for nearly one-third of the total in the country. Due to the increasing intersection between power facilities and birds, State Grid Yancheng Power Supply Company continues to carry out the protection of migratory birds and biodiversity under the framework of State Grid's "Migratory Bird Lifeline" public welfare project.

At the same time, State Grid Yancheng Power Supply Company, together with rescue stations, public security, forestry departments, and numerous social organizations, has established a joint rescue mechanism for the Oriental White Stork. Based on this mechanism, 11 Eastern White Storks have been successfully rescued and released from last year to this year, five of which are equipped with tracking rings with Beidou positioning function. It can be seen that the activity trajectory of the Oriental White Stork has traveled through Shandong, Tianjin, Liaoning and other places. The Oriental White Stork released into nature can smoothly adapt to wild life.

In addition, State Grid Yancheng Power Supply Company has also cooperated with local wetland management departments to carry out technical research and development. By using power big data and bird observation records, and comprehensively considering the location, height, historical nesting situation of iron towers, as well as the construction of iron towers within 5 kilometers of the surrounding area, a prediction model for nesting points of large birds such as the Eastern White Stork has been constructed. The tower locations where they may nest have been selected, and protective measures such as installing protective barriers have been taken in advance. By utilizing this system, the utilization rate of the line protection device can be increased by 70%, and the cost can be reduced by over 5 million yuan.

At the beginning of autumn, the coldness in the north is gradually emerging. Autumn migratory birds have arrived at wetlands in Yancheng one after another. They rest and forage here, preparing adequately for winter. Amid the blue sky and clear water, birds dance and soar freely, painting a new ecological picture.
