| Summary: | East Nusa Tenggara Province (NTT), despite having high potential of solar
energy, has the lowest electrification rate in the country. Concentrated solar power
(CSP) plant is one of the best technology to make use of NTT’s solar potential. In
this research a CSP plant with Brayton cycle and ORC is modelled after the solar
potential in Kupang, NTT. Three working fluid for ORC is analysed based on
thermodynamic efficiency and safety. The economics of the plant is analysed and
the Levelized Cost of Electricity of a CSP plant with and without a thermal energy
storage (TES) is compared. CSP plant with Brayton cycle and ORC has a power
output of 2,014 – 11,008 kW throughout the day. All three working fluids choice
met safety criteria. R141b has the highest thermodynamic efficiency so it was
chosen as ORC working fluid in the final design. CSP plant with TES requires
Rp421,191,784,800.00 of initial investment. This project has Net Present Value
(NPV) of Rp129,969,297,579.00 at 11.11% Internal Rate of Return (IRR) and
payback period of 11.23 years. CSP plant with TES has an LCOE of Rp979.00
while the one without has an LCOE of Rp734.00. |
