OPERATIONAL OCEAN ENERGY PROJECTS
The 500 kW Oscillating Water Column (OWC) plant in Yongsoo, Jeju Island, is being installed in Jeju since 2012. The plant, which is developed by KRISO and funded by MOF, is equipped with a couple of turbines and generators of 250 kW capacity and is located 1km away from the coastline. It is currently going through an ongoing inspection for grid connection by the 22.9 kV AC underwater cable. The construction of the demonstration OWC plant has recently been completed, in November 2014, and will start operating in March 2015.

The 200 kW High Temperature-Difference Ocean Thermal Energy Conversion (H-OTEC) by KRISO in Goseong was completed in December 2014 and is expected to be utilized within 1~2 years. Unlike the previous OTEC which used the temperature difference between surface water of 20~35ºC and deep sea water that maintains 2ºC, the H-OTEC utilizes heat source generated from other power generation facilities, reaching up to 75ºC. This allowed the newly installed H-OTEC to be highly efficient and it is expected to generate 1,580,000 kW a year for 70 households, saving 339 TOE of oil, and 742 tons of CO2.

PLANNED DEPLOYMENTS
The project targeted technical development and demonstration of a pendulum-activated, high-efficiency and high-persistence 300 kW floating wave energy converter (WEC) with an operating capacity applicable to deep sea conditions. The process of actualizing the 300 kW pendulum wave energy converter is being continued by KRISO and MOF, and has currently secured its source technology and completed its detail design in 2014. The development project started in 2010 and is expected to end by 2016.
