Tidal energy pilot in Korea completes two years of clean power generation

The Uldolmok Tidal Power Station in South Korea has completed two years of electricity generation, exploiting the tides of the Myeongnyang Strait at Jindo Island.

The Uldolmok Tidal Power Station is now integrated in the Korea Tidal Current Energy Center (K-TEC), led by the Korean Institute of Ocean Science and Technology (KIOST) and being used as an open test site for tidal current energy turbines.

According to the report from International Energy Agency’s (IEA) Ocean Energy Systems (OES), a cross-flow Helical turbine with 80kW rated output is currently installed at the site.

The report further states that from September 14, 2021, until May 15, 2022, a total of 8.88MWh of electricity was generated.

KIOST is also developing a tidal current energy converter (TEC) hybrid system for remote off-grid islands utilizing dual vertical axis Darrius turbines with a rated power of 100kW.

For accumulating electricity, the energy storage system (ESS) has a total capacity of 500kWh. This hybrid system was manufactured and installed at the front side of the existing Uldolmok Tidal Power Pilot Plant to be tested in 2023, according to IEA-OES.
