We study quintessence models using low energy supergravity inspired from string theory. We consider effective supergravity with two scales m(S), the string scale, and m(Pl), the Planck scale, and show that quintessence naturally arises from a supersymmetry breaking hidden sector. As long as supersymmetry is broken by the F-term of a Polonyi-like field coupled to the quintessence field in the Kahler potential we find that the Ratra-Peebles potential and its supergravity version are generic predictions. This requires that the string scale decouples from the Planck scale, m(s)<
