en.Wedoany.com Reported - The integrated solar-storage-charging new energy (Phase II photovoltaic) project at Zhoushan Putuoshan International Airport has completed full system commissioning and was officially put into operation recently. This project is the first airport new energy demonstration project in Zhejiang Province to extend distributed photovoltaics into the airside area, achieving three firsts among airports in the province: the highest proportion of photovoltaic clean energy consumption to total electricity consumption, the largest photovoltaic clean energy storage capacity, and the first airport equipped with an integrated solar-storage-charging microgrid system.
During the construction of the Phase I photovoltaic project, Zhoushan Putuoshan International Airport established a cooperative relationship with Zhejiang Airport Financing Leasing Co., Ltd. and accumulated experience in jointly building new energy projects. On June 25, 2025, the two parties collaborated again, launching the integrated solar-storage-charging new energy (Phase II photovoltaic) project after multiple rounds of negotiation and technical feasibility studies. To balance flight safety with green energy development, the airport conducted a specialized assessment of light impact in the airside area during the preliminary phase, selecting low-reflectivity dual-glass photovoltaic modules. Through a scientifically designed photovoltaic array layout, the solar facilities were installed in the airside area without interfering with the normal takeoff, landing, and operational safety of aircraft.
The project establishes a "full-area photovoltaic + smart energy storage + fast charging network" tripartite clean energy system. A new 1.41MW distributed photovoltaic system was built, bringing the total installed capacity to 1.97MW, covering photovoltaic networks in the airside area, parking lots, and office zones. Seven 125kW/261kWh energy storage units were deployed, with a total storage capacity of 1.827MWh. During the day, surplus photovoltaic power generation is stored uniformly and released during peak morning and evening electricity consumption periods, smoothing peak-valley differences to reduce the airport's electricity operating costs. Additionally, ten new energy DC fast charging piles were added to the facility, covering the recharging needs of passenger vehicles and airport special vehicles, achieving an efficient cycle of "photovoltaic power generation—energy storage peak shaving—green electricity consumption."
Calculations show that the project's annual power generation exceeds 2.1 million kWh, all from clean renewable energy. It can save 670 tons of standard coal annually and reduce carbon dioxide emissions by over 1,680 tons, equivalent to planting 93,000 trees. The airport stated that it will continue to accumulate practical experience in zero-carbon airport construction and steadily advance the development of a zero-carbon air hub.
