Analisa Keekonomian Tarif Penjualan Listrik Pembangkit Listrik Tenaga Surya 1 MWp Bangli Dengan Metode Life Cycle Cost

Abstract

Feed-in tariff (FIT) policy has been implemented in many countries in order to improve the utilization of renewable sources of energy as an alternative energy sources. Through Permen ESDM No. 17 in 2013, the government of the Republic of Indonesia has set the FIT policy of photo voltaic system for Solar Energy Generation (PLTS). Using this policy, the government want to attract some investors for investing in solar power generation in order to achieve an optimal value of the national energy mix in 2025 where the portion of the renewable energy are 23%. The method used in calculating the electricity sales tariff is life cycle cost method, this method calculates the overall cost of a system, from planning, construction, operation & maintenance, equipment replacement, and salvage value over the lifetime of the system. In this paper, electricity sales tariff can be found by adding a profit margin in the calculation of LCOE, and LCoE is total of present value LCC divided by total of present value energy generation. The result of the electricity sales tariff calculation is Rp. 2,201 / kWh which meets with the benchmark price in FiT. Four parameter are used to analyze the economic feasibility of this electricity sales tariff, such as IRR (Internal Rate of Return), Pay Back Period (PBP), PI (Profitability Index) and PNV (Net Present Value) methods.
