The HyTide 110-5.3 horizontal axis tidal turbine, a product of Voith Hydro with rated power of 110 kW and
diameter of 5.3m, was installed in Jindo of Korea in the Spring of 2011. The site was used to test the turbine
under extreme conditions. It has been tested for three months in 2012, resulting in the availability of 94%
and rotor power peak of 130 kW.

New Developments
The Yongsoo wave power plant, a pilot plant of 500kW OWC (Oscillating Water Column) wave energy
converter which has been developed by KIOST and funded by MLTM, is being constructed at Yongsoo, Jeju
of Korea. However, its completion has been delayed for more than a year, mainly because of exceptionally
frequent typhoons in the region during the summer period of 2012. The construction of the caisson
structure and underwater power cable will be finished in the second quarter of 2013. Then the installation
of the generation equipment will be followed in the third quarter, expecting to start the test operation in
late October 2013. A couple of turbines and generators of 250 kW capacity were manufactured in 2010
and an integrated system of generator and power control module was extensively tested in the laboratory
of Korea Electrotechnology Research Institute in 2011. A caisson structure of 15,000 tonnes has been
constructed at a test site, which is 1 km off the coastline of Yongsoo in April 2012. An underwater cable
between the caisson structure and a power house on land is being deployed and it will be connected to
the national grid later.
