Dongshan county ofZhangzhou city located on the southern coast of southeast China’sFujian province, boasts abundant silica sand reserves exceeding 200 million tons and a silicon content of over 97 percent. It is the largest production base of high-quality silica sand in China and ranks first in Asia for its abundant, high-grade, and extensive resources.
As China’sphotovoltaic industry maintains robust development, Dongshan county is striving to build an entire industrial chain of new materials and renewable energy with an output value exceeding 10 billion yuan ($1.4 billion), in which local power supply companies have played a crucial supportive role.
As a key facility set up by Fujian province for producing glass and new materials, the Lingang Economic Industrial Park in Dongshan county boasts a 50,000-ton dock and primarily facilitates the import of raw materials for producing photovoltaic and new glass materials and the export of finished glass.
In 2023, the export value of finished glass from the Qibin terminal within the industrial park reached a historical high of 388 million yuan, a year-on-year increase of 326.4 percent.
To address the high energy consumption of enterprises, the State Grid Fujian Dongshan Power Supply Co. Ltd. has encouraged companies within the industrial park to shift their non-critical production activities to off-peak periods, and adopt energy-efficient variable frequency motors and energy-saving lighting solutions. These measures have allowed Zhangzhou Kibing Glass Co. to cut its monthly electricity costs by 6 percent and reduce carbon emissions by 80 tons, yielding both economic and ecological benefits.
“We have installed an 800 kW shore power systemat the Qibin terminal, which not only reduces the fuel consumption of ships while docked and improves the environmental conditions of the port and its surrounding areas, but also helps lower transportation costs for both raw materials and finished products,” said Xu Yongping, project leader of the shore power system.
It is reported that the shore power system now contributes to an annual reduction of 1,810 tons in carbon emissions. Additionally, solar panels have been installed at the Qibin terminal to supply energy for lighting, leading to a reduction of carbon emissions by about 400 tons each year.
So far, eight prominent companies in renewable energy have settled in the industrial park, creating a large, intensive, and park-based development pattern for photovoltaic and new glass material industries.
Currently, the State Grid Fujian Dongshan Power Supply Co. Ltd. is working to support the high-quality development of Dongshan’s green energy industry in response tothe challenges faced by the industrial park such as high operational and maintenance pressure of electrical facilities.

从“一粒砂”到“一条百亿产业链”
人民日报记者 施 钰
东山县位于中国福建省南部沿海，拥有丰富的硅砂资源，硅砂资源储量2亿多吨，含硅量高达97%以上，是中国最大的优质硅砂生产基地，其储量之多、品位之高、规模之大在亚洲首屈一指。
当前，光伏产业迎来发展“风口”，为抓住绿色发展机遇，东山围绕“一粒砂”做成“一条产业链”，持续打造产值超百亿的新材料新能源产业链，其中当地供电公司对产业发展起到重要支撑作用。
东山县临港经济产业园是福建省设立的玻璃及新材料产业基地之一，目前已拥有5万吨码头泊位，港区来往货物主要供应光伏及玻璃新材料生产原材料的进口及成品玻璃的出口。2023年，福建漳州东山县旗滨码头出口的成品玻璃规模创历史新高，达到3.88亿元，同比增长326.4%。
针对该园区企业高能耗高用电的特点，国网东山县供电公司提出用电时段优化建议，将非关键生产活动调整至电价低谷时段，同时采用高效的变频电机和节能灯具降低能耗。凭借这些举措，漳州旗滨玻璃有限公司每月节省6%的用电成本，实现碳减排80吨，实现了经济收益、绿色效益的双增长。
“我们在码头安装了1套800千瓦的岸电设备，不仅能减少船舶停靠期间的燃油消耗，改善港口及周边区域的环境，还有助于降低企业原料及成品的运输成本。”旗滨码头港口岸电项目负责人许勇平说。据悉，港口岸电投用后每年实现碳减排1810吨。不仅如此，通过在码头进行绿色照明改造，安装的光伏板每年可减少碳排放约400吨。
如今，这里已入驻8家优质新能源企业，形成规模化、集约化、园区化的光伏及玻璃新材料产业发展格局。聚焦园区用电设施运维压力大等问题，国网东山县供电公司正不断发力，助力东山县绿色能源产业高质量发展。
