The Prodigy, the Kooks, Ian Brown and Stereophonics are among the other acts scheduled to appear.
Tickets for the festival will go on sale on Friday morning.
Other acts on the bill include Lenny Kravitz, Maximo Park, the Charlatans, The Hoosiers and current chart topper Duffy.
Alanis Morissette, Sugababes, Travis and Amy MacDonald are also set to perform alongside such indie bands as Scouting for Girls and the Pigeon Detectives.
The festival is now in its 13th year.
Winehouse was due to perform last year but pulled out at the last minute citing "health issues".
At the time, festival director Simon Moran said he would "gladly welcome her" back in 2008.
Kanye West, the Foo Fighters, Mika and the Killers were among the acts who appeared in 2007.
