A series of studies have been and are being carried out to get an innovative engineering-based method of changing the paradigm of a breakwater as a dissipate wave energy structures into a coastal structure that protects the coast by capturing wave energy (Catchwater Shore Protection-CSP) to turn generator turbines. This work estimates the potential utilization of wave energy around the South Coast of Bali Island to be used as electric power with a multi slope CSP structure (CSP-MS). Wave data for 15 years (2005-2019) at 4 observation points were gathered up from the European Center for Medium-Range Weather Forecasts (ECMWF). The representative wave analysis (Hn, where n is the return period year) yields a base value of H10 = 2.79 m with T10 = 13.36 s; Hs = 2.40 m with Ts = 12.33 s; H50 = 2.24 m with T50 = 11.89 s and H100 = 1.87 m with T100 = 10.75 s. The empirical analysis results indicate that the efficiency of capturing wave energy is ranging from 34.8% to 43.3% using CSP-MS.
