5.9MW distributed photovoltaic project successfully connected to the grid, creating a new benchmark for green manufacturing
On the roof of the nuclear grade valve leading enterprise's factory building, rows of photovoltaic panels are converting sunlight into green electricity, writing the low-carbon transformation practice of high-end manufacturing industry. On the shore of Bohai Bay, the factory area of Dalian Dagao Valve Co., Ltd. welcomes a new atmosphere.
At 10:30 am on May 29, 2025, Xiamen Guomao New Energy Dalian Dagao Valve 5.9MW rooftop distributed photovoltaic project was officially connected to the grid for power generation, marking a solid step forward for this leading nuclear power valve enterprise on the path of green manufacturing. The project adopts a development model of "spontaneous self use, surplus electricity connected to the grid", covering the roofs of the existing factory buildings of the enterprise, becoming another demonstration project in the industrial and commercial photovoltaic field in Dalian.
Green turn of nuclear grade valve leader
As a national high-tech enterprise and a national key "little giant" enterprise specializing in precision and innovation, Dalian Dagao Valve is well-known in the field of key nuclear power equipment. The company is one of the designers and manufacturers in the industry with the most types of nuclear level 1 valve qualifications. Its research and development of nuclear level 1 blasting valves with international advanced level has solved one of the three key equipment bottlenecks of the Guohe No.1 demonstration project.
While serving the national nuclear power strategy, Dagao Valve actively implements the national "dual carbon" strategy. In the increasingly prominent trend of environmental pollution, climate change, and global energy structural shortage, the company accelerates the promotion and application of new energy, which has become a major strategic choice for countries to cultivate new economic growth points.
Green benefits of photovoltaic projects
This rooftop photovoltaic power station with an installed capacity of 5.9 megawatts is expected to generate millions of kilowatt hours of electricity annually, significantly reducing the cost of electricity for businesses.
The project adopts efficient photovoltaic modules and intelligent management system to achieve real-time monitoring of the photovoltaic power generation process, ensuring the efficient and stable operation of the power station. According to industry data, projects of similar scale can reduce thousands of tons of carbon dioxide emissions annually, equivalent to the environmental benefits of planting tens of thousands of trees.
Green practices under policy guidance
The green action of Dalian Dagao Valve coincides with a critical period of national energy transformation. The report of the 20th National Congress of the Communist Party of China clearly put forward the dual goals of "actively and steadily promoting carbon peak and carbon neutrality" and "actively, safely and orderly developing nuclear power". As a pioneer in the bottleneck technology of nuclear power, Dalian Dagao Valve has achieved a breakthrough in the localization of nuclear grade valves while actively embracing the green energy revolution, demonstrating the social responsibility and forward-looking vision of a leading enterprise in high-end manufacturing.
When nuclear power technology and photovoltaic power generation complement each other, it is not only a factory's energy transformation, but also a firm footprint of a manufacturing powerhouse moving towards green, setting a new example for the industry's green transformation.
