Founded in 1999. Traditionally, there was a "small" edition and a big edition each year. In 2002, the small edition failed to sell out its 20,000-person ticket capacity (only 15,000 tickets were sold) and thereafter, Trance Energy was only held once annually, at the Jaarbeurs convention center in Utrecht, Netherlands, where it has been sold out each year up to 2009. The festival gained "cult" status among Trance fans. In 2010, it failed to sell out by slight margins since it was organized on Easter week end and this was problematic for some foreign visitors (especially from Poland).
