To support the Indonesia Government in achieving SDGs' target No. 7, developing environmentally friendly alternative energy is necessary. This research seeks to support the development of a wave energy power plant with great potential in Indonesia as an archipelagic country. The factors are collected from previous research to be considered in developing the design of a sea wave energy power plant. Determination of the location begins by collecting several locations that have been recommended by previous researchers, generally from the consideration of the magnitude of the potential for ocean wave energy. Simeuleu, Nias, Siberut, and Enggano islands have an essential local cost of providing electricity higher than the electricity tariff generated by ocean wave energy power plants, which is economically advantageous. Considering the criteria for potential wave resources, the essential cost of providing electricity, and potential replacement of existing D/G power plant, the Analytic Hierarchy Process (AHP) method synthesizes Nias island as the best location for ocean wave energy power plants. All locations with a significant potential for ocean wave energy are located in earthquake and tsunami-prone areas. Therefore, the design of power plants must be resistant to earthquakes and tsunamis.
