Feasibility Study on Wave Energy Power plant with Oscillating Water Column System in Bawean Island Seas Indonesia

As a huge archipelago with 17,480 islands, Indonesia still has difficulties to electrify all of its islands especially on the remote ones (areas) because of a power grid coverage limitation of National Electrical Company (PLN). This research discusses the potential calculation of sea wave power conversion by utilizing Oscillating Water Column (OWC) system in remote islands, especially on Bawean Island Seas. OWC system is chosen because of its advantages compared to other systems and also because of its suitability towards sea and coast areas in Indonesia. Kim Nielsen and David Ross Law were used for the power calculation. The research took data sampling during one month in 2015 with the result of wave height average of 2.09 meters. That obtained data resulted wave energy of within 270.19 and electrical power output of about 52.7 kW by using Oscillating Water Column system. Based on this result, Break Even Point (BEP) for one plant covering 117 houses will become zero in the period of 3 years 8 months.
