Uldolmok Tidal Power Station (Stage One: Pilot)
Device Status: 
In Operation
Technology: 
Tidal Barrage
Project Scale: 
Pilot Plant
Installed Capacity: 
1 MW (increasing to 90 MW in 2013)
Description: 

The Uldolmok Strait experiences tidal water speeds that exceed 6.5 m/s with the width of the strait being approximately 300 m due to the average tidal range of 3 m over the entire channel and the tidal phase difference of 100 min between both ends. The water level difference through the Uldolmok Strait is 2 m. Gorlov triple helical turbines of 1 m diameter and 2.5 m length are used to collect cross-flow tidal fluctuations.

Location: 

The Uldolmok Strait, at Jindo Island, South Jeolla, South Korea.

Process Status: 

Korea East West Power Co. and South Jeolla Province signed an investment agreement in 2006 to develop a tidal plant in Jindo. 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.

 

The plant was commissioned in May 14, 2009 by the South Korean government. 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. Additional 500 kW was commissioned in June 2011.

Licensing Information: 

The Low Carbon Green Growth Basic Act (Feb 2009) and the Green Growth 5-Year Plan: Restructuring S&T R&D Policies (July 2009) were passed in hopes that “A national paradigm that aims to deal with the challenges of climate change while at the same time create jobs and restore growth by minimizing environmental degradation and carbon emissions.” By 2020, South Korea hopes to produce 5,377 GWh/yr from ocean renewable energy. This could reach 113,000 residents and reduce carbon dioxide emissions by 2.3 million tons.

Key Environmental Issues: 

No studies have been conducted to analyse the direct environmental effects of the pilot turbines, much less the effects done one the project expands to the planned 90 MW stage two of development. However, the project will reduce reliance on greenhouse gases for energy in accordance with UNFCCC.

Study Status: 
Uldolmok Tidal Power Station is located in Korea South.
