Performance of Generating Plant - World Energy Council

Performance of Generating Plant: Managing the Changes Executive Summary World Energy Council 20073• associated with specific performancemetrics.• To provide means to investigate whetherit is possible to employ such analytics to“normalise” plant performance acrossmarkets to promote benchmarking andidentify “top of the class” performance.• Means to extend this framework toconsider other forms of metrics or indices.For example, significant new work isbeing undertaken for measuringenvironmental performance and/orsustainability metrics.To address this, the PGP Committee hasdeveloped a new computer-based tool toevaluate and compare plant performancemetrics. A series of case studies have beenconducted to illustrate how to better apply andleverage both peer group data as well as thebroader set of indicators. The model also fullydocuments and provides a basis of calculationsfor all major current performance indicators.Overview of the PGP Technical &Commercial Performance ModelThe model provides means to analyse manyfacilities, even for technologies that the userdoes not fully understand. It provides a mediumfor analysing and presenting a thoroughavailability and economic comparison for variousfacilities, technologies, markets, and obligations.It serves as an educational tool to facilitate thequick comparison of plants that are difficult tocompare side-by-side.How to leverage plant performance data?The PGP Committee has developed aTechnical & Commercial Power PlantPerformance Evaluation Model to help theevaluation process.The model allows comparing variousperformance metrics across the plants including:• Commercial Availability• Traditional Availability• Capacity• Capability• Revenue• Costs• Profitability (or Operating Margin)In order to attain these comparisons, there mustbe a simulation engine to model the systemsthat generates these comparison metrics. Withthis in mind, the following models for each planthave been integrated into the PGP model:• Market Model• Demand Model• Capacity Model• Availability Model• Financial ModelIf a comparison against a certain planttechnology is desired, but knowledge of this typeof plant is limited, then the model facilitates thecomparison by providing a library of typicalplants from which to choose and populate the
