Among the plant operators in Prewin there is an interest to learn more about maintenance costs. Therefore a survey on maintenance costs have been conducted. Results from 78 plants are now available for operators who participated in the survey.  We decided to continue the possibity to participate in the survey.

Also non-Prewin participants are invited to complete the surveys (availability and maintenance costs). The data will be kept confidential and is used to present the results in such a way that individual data cannot be retrieved from the presented results.  In turn of submitting both surveys you will receive the results from the first analysis presented at the Prewin meeting in Copenhagen, June 15-16. Based upon the amount of new participants updates will be present regularly at the Prewin meetings and will be available for the participants of the survey.

As Prewin network we issued a questionnaire to waste to energy plant operators on availability. Data from 208 lines processing 2750 tonnes of waste per hour has been gathered. Results from availability, unplanned outage and overall equipment effectiveness are available. Further it shows clearly different maintenance strategies (time between planned stops and length of planned stops). A powerpoint presentation with results is available for participants in the private part of the website. More data from plants is always welcome.
