Method & Evidence

AimTo evaluate the wave energy potential and assess the economic viability of Wave Energy Converters (WECs) in the South Java Seas.

MethodQuantitative analysis and economic simulation

ProcedureWave hindcast data from NOAA and ERA5 (2008-2018) were processed to estimate significant wave height, mean wave period, and mean wave direction. Two locations in the South Java seas were identified. An economic simulation was conducted for a multi-point absorber WEC to determine the Levelized Cost of Electricity (LCOE).
