Analysis of operating wind farms:
Learning the lessons from operational sites

2 & 3 July 2012
Lyon Convention Centre, Lyon, France

Presentations are available free of charge

In response to requests from members, EWEA’s second technology workshop focused on the post-construction assessment of wind farms.

This was a natural follow-on from pre-construction wind resource assessment, which was the focus of the first EWEA technology workshop (“EWEA Wind Resource Assessment Technology Workshop”, Brussels, May 2011) about which 97% of the participants said they were very satisfied!


As projects get bigger so does the impact of predictions not matching actual production.

  • How can differences between pre- and post-construction analysis be minimized?
  • What best practice is the industry working towards?
  • Are construction and operation teams talking to each other?

The workshop took place over one and a half days with five sessions focusing on:

  1. Data from operating assets: what are they really worth?
  2. Post-construction yield analysis techniques
  3. Power performance
  4. Availability and asset monitoring
  5. Turbine by turbine performance
Attendees heard from industry specialists from the following industry leaders:

Pre-workshop survey results presented in Lyon

What is the industry standard for post-construction yield analysis techniques? Delegates found out in Lyon!

Many thanks to the 50+ organisations that took part in the pre-workshop survey!

The survey gauged the level of industry consensus on methods for predicting the long-term energy yield of operating wind farms and led to debate as to the path that the industry should be taking with respect to long-term production forecasting.
