A new model of coordinated carbon-reduction services across the industrial chain, guided by the cooperation principle of “premium flexibility,” has been developed by the Shaanxi Province-based State Grid Tongchuan Power Supply Co., Ltd., together with government departments, enterprises, and financial institutions.
Tongchuan City is the largest aluminum processing base in Shaanxi Province. Against the backdrop of China’s “dual carbon” goals (carbon peaking by 2030 and carbon neutrality by 2060), traditional energy-intensive industries are facing unprecedented pressure for transformation. In March 2024, State Grid Tongchuan Power Supply initiated a comprehensive energy-saving and carbon-reduction framework through shifts in concept, approach, and objective, an effort to accelerate the green transformation of industries in resource-based cities.
In 2024, to implement its new service model, the company visited a total of 12 enterprises and released 12 energy-efficiency diagnostic reports. By generating visual analytical charts through digital systems, energy consumption became “clear at a glance.”
Shanxi Mingdi Aluminum Co., Ltd. is one of the enterprises benefitting from this model. With the support of State Grid Tongchuan Power Supply, the business completed the construction of a rooftop photovoltaic power generation project with an annual output of 14 million kilowatt, significantly enhancing the green competitiveness of its products and its market influence.
State Grid Tongchuan Power Supply has placed great emphasis on balancing carbon-reduction costs with corporate profits in its services, and helping all stakeholders achieve win-win outcomes in the green transition.
The rooftop photovoltaic project of Mingdi Aluminum is a prime example of an innovative multi-party cooperative business model: the enterprise provides rooftop resources, the new energy company invests in the construction of facilities, and the power supply company provides grid access and energy-efficiency services. This model not only reduces enterprises’ energy costs but also generates stable returns for investors, achieving a unified accomplishment of economic, environmental, and social interests.
By the end of 2024, in the Dongjiahe Circular Economy Industrial Park in Tongchuan, eight enterprises had launched rooftop photovoltaic projects, and eight integrated energy projects had been implemented.
To ensure the sustainability of its services, State Grid Tongchuan Power Supply has built five teams working to integrate energy-saving and carbon-reduction services into routine power supply operations, and deliver tailored solutions for each customer.
