| Summary: | The West Nusa Tenggara Government through the Provincial RUED has consistently begun to
consider the electricity needs supplied from renewable energy based generators. One potential
source of energy is tidal current. The Alas Strait is one of the potential waters in Nusa Tenggara
that can be used as a location for tidal current power plant. Thus, a potential study will be
carried out by simulating hydrodynamic models and reviewing the generation of tidal currents
in the potential area with an aim to meet the electricity needs projection of West Sumbawa
Regency in 2050 around 82.30 GWh anually. Based on the analysis, the coordinates -8,640,
116,702 is the optimal location for the tidal current power plant with a median current speed
of 0.82 m/s. The electric power calculation refers to Sustainable Energy in Ireland document
and the selection of tidal current energy converter refers to the Final Survey and
Characterization Tidal in Stream Energy Conversion (TISEC) Devices document. Based on the
analysis, TidEL, developed by SMD Hydrovision Company, was selected as the tidal current
energy converter. The annual theoretical power generated by the potential site is 0.13 GW per
instrument. Each instrument produces an annual technical power of 0.028 GW which is
equivalent to 16.22 GWh in a year. To meet the demand, 7 units of TidEL instruments are
needed. For an investment period of 25 years with the operation of the tidal current power
plant starting in 2025, the cost of electricity is IDR 8,272/kWh. The price is still 3 times higher
than the regional BPP nominal of Tambora distribution system which means the electricity
cannot be sold to PLN. Although currently the technology of tidal current power plant has not
been able to provide commercial financial value, along with the development of technology
there may be a significant decrease in the price of the instrument and its maintenance, so that
this technology allows it to be developed and carried out commercially in the future.
