Abstract In Gas turbine-based combined cycle power plant market, the customer conducts an economic evaluation of competitive products to decide their buying option. There are different methods to calculate the economics of a power plant like Levelized cost of electricity (LCOE), Net present value (NPV) and payback period. LCOE methodology is commonly used for lifecycle cost analyses for combine cycle power plant that covers cost details of the plant and plant performance over the complete lifetime of a power plant from construction to retiring. Typically, it includes a combine cycle power plant ownership costs (Total plant cost and operating & maintenance cost) and combine cycle power output and efficiency. This LCOE method is helpful to compare power generation system that use similar technologies. This paper encompasses the LCOE calculation method, assumptions & approach to analyze the impact of key parameters of the electrical generation cost. They key parameters includes combine cycle output, combine cycle efficiency, fuel cost, annual operating hours, capital charge factor, annual operating hours, power plant life, discount rate, nominal escalation rate, operating & maintenance cost. This paper analyses result will provide insights to the customer & Gas turbine-based OEM (Own Equipment Manufacturing) companies to focus on different area/parameters to reduce the unit cost of generating electricity.

Abstract Gas turbine-based combine cycle (GT-CC) economic evaluation is very important to bring together own equipment manufacturing companies (OEM’s) and power plant owners. The fuel cost & cost of electricity play the major role in economic evaluation which drives the decision during the bidding. The first portion of this paper encompasses the different cost analysis methods like Net Present Value (NPV), Internal Rate of Return (IRR), Levelized Cost of Electricity (LCOE) and Pay Back Period (PBP) for different fuel costs and electricity prices. The second portion of the paper covers the delta cost benefits due to improvement in the combined cycle degradation GT-CC operators or customers are looking for the opportunities to control and minimize the degradation of the gas turbine power plant which directly impact the profitability. The customer or operator always monitor the plant performance to understand the life cost impact on performance degradation. This paper will help the customers & GT-CC OEM companies to focus on different area to reduce the unit cost of generating electricity, decide to move forward with the project during the proposal and improve the business at various regions based on fuel cost and global geographical political situations. Also, the reader can digest the benefits of improved degradation curve over the normal curve.

Pada penelitian ini, penulis melakukan review penggunaan fluida kerja ORC yang disimulasikan menggunakan EES dan melakukan review pada beberapa jurnal yang dilakukan sebelumnya. Fluida kerja yang dianalisa adalah isopentane sebagai fluida kerja yang dipakai, isobutane dan R245fa, dimana isobutane menghasil power output yang lebih tinggi dibandingkan dengan fluida sekunder lainnya karena enthalpi uap yang masuk ke turbine dan enthalpi uap yang masuk ke kondenser yang dihasilkan lebih tinggi dan ini menyebabkan kalor yang masuk ke dalam sistem ORC lebih tinggi dibandingkan dengan fluida kerja lainnya. Pada sistem ORC banyak pilihan fluida kerja dan bisa diaplikasikan dalam sistem baik secara aktual maupun masih dalam research, baik dalam off design dalam bentuk paper, jurnal maupun aplikasi teknologi secara langsung dalam pembangkit listrik panas bumi, waste heat recovery plant atau tipe combine cycle lainnya. Pada beberapa sistem yang diteliti, R227ea memiliki efisiensi thermal yang lebih baik daripada fluida sekunder lainnya. Sedangkan pada waste heat power plant, R134a memiliki efisiensi yang lebih baik dari fluida sekunder yang diteliti. Dan pada research lainnya HFE-301 memiliki efisiensi thermal sebesar 85% pada aplikasi Radial inflow turbine dengan kecepatan sekitar 60.000 rpm dan menghasilkan daya sebesar 1,5 kW.
