Analysis of ocean waves in 3 sites potential areas for renewable energy development in Indonesia

During the recent years, Indonesian government rapidly increase the electrification program which is mainly using coal energy. However, some areas are still need any supports of electricity. As an archipelagic state, Indonesia is surrounded by seas which is potential for developing the wave energy. Three areas were selected for examining the wave energy potential i.e., Meulaboh (in Sumatera), South Kuta (in Bali) and Manokwari (in Papua), which is the representative of the region in west, middle and east of Indonesia, respectively. Ocean wave characteristics were analyzed for each monsoon from 2012 to 2017, based on ocean wave forecasting using Sverdrup, Munk and Bretschneider method. The electrical power calculations were done by using Floating Oscillating Water Column formulas. Based on our analysis, the average of highest significant wave heights and periods in 3 sites happen in the West Monsoon and the lowest average of significant wave heights and periods mostly happen in the East Monsoon. Thus, among the three locations that were examined, South Kuta Bali is the best location to develop wave energy.
