Alstom will manufacture six ECO 110 3MW turbines for the Gowon wind project, 170 kilometres east of Seoul. It is due to be commissioned by the end of 2015.
Gowon is being jointly developed by South Korean firm Dae Myoung, part of Dae Myoung GEC, and Japanese developer Eurus Energy.
It is Alstom's second order in South Korea this year. In March, the manufacturer received an order from GS Engineering and Construction for 10 ECO 110 3MW turbines for the Gimnyeoung project in the south of the country.
In October 2013 a draft plan was made to the National Energy Plan to increase the wind power target from 7.3GW to 12GW by 2030.
Eurus Energy has previously contracted Alstom to supply turbines to its Japanese projects.
