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 &amp; cost of electricity play the major role in economic evaluation which drives the decision during the bidding.The first portion of this paper encompass 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 and electricity cost. The second portion of the paper covers the delta cost benefits due to improvement in the combined cycle degradation There is a strong incentive for GT-CC operators to minimize and control performance degradation of the plant, as it directly affects profitability. The customer or operator always monitor the plant performance to understand the life cost impact on performance degradation.&nbsp;This paper will help the customers &amp; gas turbine based&nbsp; OEM companies to focus on different areas to reduce the unit cost of generating electricity, decide their electricity selling price to sustain 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.

ASME 2021 Gas Turbine India Conference (GTINDIA2021)

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
