Recently, the Ministry of Industry and Information Technology released the National Recommended Catalogue of Energy-saving and Carbon-reduction Technology and Equipment in the Field of Industry and Information Technology (2025 Edition), in which the Demonstration Scenario of Optimal PV-ESS-Charging DC Flexible Building at Gangwan No.2 · Shuangbo Base of Zhuhai Hi-tech Zone has been included.
As a core policy instrument for the country to implement the dual carbon goals and advance the green and low-carbon transformation of the industrial and information technology sector, the Catalogue serves as a guiding indicator for steering technological innovation in the industry and optimizing the direction of industrial upgrading.
The selected Demonstration Scenario of Optimal PV-ESS-Charging DC Flexible Building is spearheaded by a state-owned enterprise affiliated to Zhuhai Hi-tech Zone. The project innovatively integrates technologies including building-integrated photovoltaics, high-efficiency energy storage, DC microgrids and DC air conditioning, and constructs an all-DC energy ecosystem with the collaborative operation of “generation-grid-load-storage”. It has effectively improved energy utilization efficiency and power supply reliability, filling the gap in the field of PV-ESS-Charging DC flexible buildings in Zhuhai City. The successful inclusion in the national promotion echelon of energy-saving and carbon-reduction technologies marks that the new energy technologies applied at Gangwan No.2 have reached the domestic leading level in the field of energy conservation and carbon reduction.
Since the Demonstration Scenario of Optimal PV-ESS-Charging DC Flexible Building was put into operation in the park in September 2023, it has generated an annual photovoltaic power output of about 700,000 kWh, driving a 43% reduction in the park’s annual carbon emissions. With tangible emission reduction results, it has provided a replicable and promotable practical model for the green upgrading of industrial parks.
