ETD recommended by European supplier for Cost & Performance Analysis Work

ETD Consulting has been commended by a leading European energy supplier for our detailed cost and performance analysis work relating to their CCGTs. In a comprehensive 12 month project, ETD performed both 'top down' and 'bottom up' analyses to determine correlations between reliability performance, operating mode, maintenance expenditure and component life both historically and for predicted future operation.

ETD can perform cost and performance analysis work worldwide and bring real benefits to your plants. Read more about our service here.

For reasons of client confidentiality, an anonymised version of the client recommendation appears below:

ETD completed a comprehensive study and evaluation of start costs associated with [two] CCGT’s using top down and bottom up analyses. This required the collection of all maintenance and failure history, operation, cost and reliability data for both … CCGT’s. The information was then used to perform a primarily bottom up investigation combined with aspects of top down analysis to determine correlations between reliability performance, operating mode, maintenance expenditure and component life both historically and for predicted future operation.

…The main start cost components required for consideration were cycling cost impact using statistical analysis, future cost projection scenarios, additional maintenance costs due to cycling using bottom up style analysis, plant performance analysis which included forced outage data analysis by area i.e. GT, HRSG etc. High Impact Low Probability Events (HILPE) were also included in the analysis, a remaining life assessment of critical HRSG components including a fatigue life assessment was carried out. The report also included a summary of relative risk of damage based on condition assessment.

A primary objective … aside from gathering all the information …, was how this information could be presented and used to determine, without question, the additional maintenance cost associated with plant cycling based on a certain number of assumptions.
ETD provided an excellent Engineering resource which allowed [us] complete this challenging and demanding project and ETD’s Project Manager was always available to provide clarifications when necessary.
