The Three Gorges Navigation Authority announced on December 21 that the annual shore power consumption in the Three Gorges Dam Shore Power Experimental Zone has exceeded 10 million kilowatt-hours for 2023, setting a new historical record.
Shore power, also known as the "Shore-to-ship Power System," refers to ships drawing electricity from an onshore power source instead of using onboard auxiliary generators while berthed.
By replacing diesel-generated power with shore-supplied electricity, atmospheric pollutants such as sulfur oxides, nitrogen oxides and particulate matter (PM), are significantly reduced, as is the noise pollution from ships.
The Three Gorges Dam area, home to the Three Gorges Project, sees over 100,000 ships annually berth for lockage. During the days-long waiting periods for lockage, emissions from powering the ship engines threaten the air quality and ecological environment of the dam area.
It is estimated that the use of 10 million kilowatt-hours of shore power can replace the use of over 2,500 tons of fuel, which reduces emissions of various gases by an approximate 7,400 tons and saves more than 15 million yuan (US$2.10 million) in energy costs for the ships. The new record for yearly shore power consumption is representative of significant social and economic gains.
