Ningbo Zhoushan Port is "green" in the New Year, and the sea breeze blows clean electricity

Before the Spring Festival, the Meishan Port Area of Zhoushan Port in Ningbo, Zhejiang, although it has been drizzling for several days, it is a busy scene at the wharf during the Spring Festival in strong contrast with the cold weather. A few days ago, the reporter walked into this oriental port to feel the "green" meaning of the New Year here.

At the container terminal not far away, there are whistles from time to time, several 100-meter giant ships berth and set sail, and the red giant bridge cranes continue to rise and fall. Busyness is the norm in Minato Ward. Ningbo-Zhoushan Port, located on the coast of the East China Sea, will handle more than 1.324 billion tons of cargo in 2023, ranking first in the world for 15 consecutive years. In recent years, as Ningbo Zhoushan Port has accelerated the construction of port energy conservation and efficiency, the green and low-carbon development path is providing surging momentum for the Oriental Port to pursue its dream of deep blue.

At the berth of the Meidong Container Terminal in the port area, a cargo ship named Xinmingzhou 88 is unloading at the shore. Walking forward, the reporter saw two high-voltage cables as thick as small arms, one end connected to the high-voltage shore power box on the wharf, and the other end supplied power to the power, lighting and other equipment of the docked ships.

The on-site staff told reporters that in the past, during the port of the ship, the ship's domestic electricity had to rely on diesel power generation. In order to effectively change the extensive energy use in the past, the power supply company installed a shore power system at the terminal, which connects the moored vessel to the charging box on the shore through cables to provide power and lighting for life on board during the vessel's berthing at port. The use of shore power system, while replacing traditional diesel power generation, also achieves zero carbon emissions, allowing the port area to bid farewell to the "diesel smell" of the past.

Looking along the direction of the extension of the port road, the reporter found that a total of 13 such high-voltage shore power systems have been installed in 24 berths of various sizes in Ningbo Zhoushan Port. According to the on-site staff, in the past year, the cumulative power supply of these high-voltage shore power facilities has reached 1.527 million kilowatt hours. "After berthing ships use high-voltage shore power, each berth can save an average of 300 tons of fuel per year, and reduce the emission of air pollutants such as sulfur oxides and nitrogen oxides by about 30 tons. Wang Quansheng, a staff member of the Marketing and Digital Service Center of State Grid Ningbo Power Supply Company, told reporters.

With the improvement of shore power facilities, the power supply and power supply stability of the port area have also been significantly improved. As of January 31 this year, the power supply of Ningbo Power Supply Company's high-voltage shore power system reached 569,500 kWh, an increase of 272.22% month-on-month. "In just one month, we have reached one-third of last year's connected ship capacity, and the connected ship power is expected to exceed 4 million kilowatt hours this year. "Speaking of these data, the royal power saint is like a treasure.

The pursuit of green, intelligent and efficient is not only reflected in the use of high-voltage shore power in ports. At the Macy's Ro-Ro Terminal, the reporter saw a large wind turbine more than 100 meters high, and the slender blades were rotating rapidly with the whistling sound of the sea breeze.

Staff member He Ning told reporters that the "big guy" in front of him is the first grid-connected wind turbine of the wind-solar-storage integration project of the Meishan low-carbon terminal demonstration project, which is the first port decentralized wind power, photovoltaic, energy storage and microgrid integration demonstration project in Zhejiang. Each wind turbine generates about 30,000 kWh of electricity per day, which is mainly used for the daily operation of Meishan Port. "Under normal circumstances, the blades generate 5 kilowatt hours of electricity per revolution, which can keep an air conditioner in the house running for five hours. Henin said.

The reporter saw at the scene that the tower of the second wind turbine in the port area has been delivered in place. In the loud roar, the on-site construction personnel manipulated the crane to slowly lift the sectional tower to the designated position, and carried out commissioning and installation, and this project will continue until the eve of the Spring Festival. By the end of June this year, five wind turbines will rotate with the wind in the port, mirroring the "neighbor" photovoltaic panels, providing 59.17 million kilowatt hours of clean electricity for the port area every year, while reducing carbon dioxide emissions by 22,600 tons. This oriental port will be even greener at that time.
