In Gas turbine-based combined cycle power plant market, the customer conducts an economic evaluation of competitive products to decide their buying option.&nbsp; There are different methods to calculate the economics of a power plant like Net present value (NPV), Levelized cost of electricity (LCOE) and payback period. LCOE methodology is commonly used for lifecycle cost analyses for combine cycle power plant that covers inputs and outputs over the complete lifetime of a power plant from construction to decommissioning. Traditionally, it combines a power generation system’s ownership costs (Total plant cost and operating &amp; maintenance cost) and combine cycle performance (power output and efficiency). This metric is useful when comparing power generation equipment that use similar technologies.This paper encompasses the LCOE calculation method, assumptions &amp; 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 &amp; maintenance cost. This paper analyses result will provide insights to the customer &amp; Gas turbine-based OEM (Own Equipment Manufacturing) companies to focus on different area/parameters to reduce the unit cost of generating electricity.

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.
