East China's Nantong City by the Yangtze River has been requiring passing ships in the river to use onshore electricity after being docked, so as to cut emissions from the diesel-fueled generators aboard and curb air pollution.
In the past, generators would continue working after ships being berthed to support running of equipment aboard. But large quantities of hazardous substances would be produced in the process. Nantong hence resorted to electricity on the land for the docked ships in hope of creating a better environment.
It's worth pointing out that use of onshore electricity also substantially cuts the costs of the ship owners while helping promote the common good.
"For such a ship, the costs of diesel consumption around a day is 6,700 yuan (about 1,013 U.S. dollars). After switching to onshore electricity, we spend only 700 yuan (about 106 U.S. dollars), a really small fraction of the diesel costs. We can save some 20,000 yuan (about 3,022 U.S. dollars) a month," according to Yang Yi, a manager at the Nantong Port.
"Take 2017 as an example. Onshore electricity use of docked ships in Nantong exceeded one million kilowatt-hours, which helped cut carbon dioxide emissions by over 1,000 tons," said Yuan Rong, a staffer of the State Grid Nantong Power Supply Company.
Based on the existing onshore electricity facilities for the passing ships, Nantong also plans to build another 16 sets of the facilities at all its newly-constructed ports in 2018.
