The cassion-type gravity-based support structure associated with the TEC is 15 m diameter x 9.5 m height, and a total weight of 350 tons. The Korean Institute of Ocean Science and Technology (KIOST) is developing a 200kW active-controlled tidal current energy converter (TEC), which aims to develop, validate and suggest a standard model for an efficient and wide scope applicable TEC that actively manages variations in tidal current speeds and directions while controlling flow amounts. After completing factory and basin tests last year, the company produced target power generation from site trials and the system continues to operate at the site. The system can operate regardless of current direction using a specially designed turbine system, the company said.

The prototype tidal current power system directly connects a tidal turbine, a gearbox and a generator for power transmission.

In June 2011 Hyundai Heavy Industries completed the site trial of a prototype 500 kW tidal current power system at the site. The plant cost 10 million USD and has an installed capacity of 1,000 KW (1 MW), generating 2.4 GWh annually, sufficient to meet the demand of 430 households. The plant was commissioned in by the South Korean government. Hyundai Construction & Engineering was chosen to construct a test power plant, while Hyundai Heavy Industries was named to develop generators and Iljin Electric was chosen to manufacture mechanical equipment.

and South Jeolla Province signed an investment agreement in 2006 to develop a tidal plant in Jindo. The plant additionally functions as a sea test facility for tidal current energy. The site includes a jacket-type support structure measuring 50 m tall x 36 m long x 16 m wide with a total weight of 1360 tons. This provide the advantage of simplified design and exploitation of the double-action tidal power plants Due to its axial symmetry, the turbine always develops unidirectional rotation, even in reversible tidal currents.

Long helical blades run along a cylindrical surface like a screw thread, which create a reaction thrust that rotates the turbine faster than the flow of water itself. The Uldolmok Tidal Current Power Pilot Plant currently produces tidal current energy using a cross-flow Helical Turbine (1 m diameter x 2.5 m length). According to earlier studies the annual energy density of the Uldolmok Strait is 52.1MWh/m 2. The tidal range is up to 4/5 in spring tides and around in the neap tides. The Uldolmok Strait experiences peak tidal current speeds of up to 6 m/s with the width of the strait being approximately 300 m, and a water depth of 20 to 32 m below datum level. The southwestern sea of Korea contains an archipelago with several straits through which strong tidal currents flow, which are advantageous for the development of tidal current energy.
