Work begins on worldÂ’s largest tidal power plant

Wando Hoenggan Tidal Plant delivers 300 MW of renewable tidal energy for South Korea, using Rotech Tidal Turbine technology, underwater engineering, and Hyundai fabrication to harness predictable marine power and advanced fluid dynamics.

Lunar Energy Limited and Korea Midland Power Company Limited KOMIPO, a spin-off of Korea Electric Power Corporation, signed a memorandum of understanding to begin development and construction on the world's largest tidal-power project.

Construction of the $600 million Wando Hoenggan Waterway Tidal Plant is already under way off the southern coast of South Korea and is scheduled for completion in January 2015. Once operational, the facility will supply 300 megawatts MW of renewable energy to the region, with examples like a powerful tidal turbine already delivering power to onshore grids elsewhere.

Known for its considerable expertise in underwater engineering and fluid dynamics, Lunar Energy associate Rotech Engineering Limited will provide design optimization and specialist components for the project, and an underwater turbine success illustrates the potential of such designs in practice. Lunar Energy has a worldwide in-perpetuity license to exploit the commercial use of the Rotech Tidal Turbine RTT technology, a design patented in the UK by Rotech.

Under the April 2008 agreement, Hyundai Samho Heavy Industries, a subsidiary of Hyundai Heavy Industries Company Limited, was selected to handle the fabrication and installation of 300 RTTs, each with generating capacities of 1 MW, similar in scale to a planned tidal energy farm in Scottish waters.

Tidal energy is still a relatively unexplored source of renewable energy. Tidal mills have been used since the Middle Ages, but it was not until the 1960s that the first tidal power plant began operating. Though more predictable and stable than wind power, tidal generation was generally curbed because of high costs and limited areas of operation, but a Scottish tidal project has demonstrated growing viability in recent years. In recent years, advances in underwater technology and turbines, such as those designed by Rotech, have brought about renewed interest in tidal power generation, as tidal projects gain momentum across global markets.
