Forecasting
All forecasts are wrong,
but some are useful.

Global Energy Forecasting Competitions
5/12/2012: Forecasting competitions are a great way to test new methods and obtain a realistic evaluation of how good they are. So I’m delighted that the IEEE is organizing an energy forecasting competition …
2/19/2014: The 2012 GEFcomcompetition was a great success with several new innovative forecasting methods introduced.
8/18/2014: GEFCom2014 is the most advanced energy forecasting competition ever organized, both in terms of the data involved, and in terms of the way the forecasts will be evaluated.

Facts
2-year cycle
Small organizing committee
Small prize money
Free (or close-to-free) platforms
Participants with diverse background
Some winners not from power & energy community
Some winners hate writing academic papers
Difference between top teams in renewable and load forecasting tracks
…
Lessons learned
You cannot please everyone
Remember THE purpose for organizing the competition
There are not many true experts in energy forecasting
Forget political correctness
Data and technical issues may happen any time
KISS – keep it simple, stupid
It’s A LOT OF WORK …
