In this paper we consider the unit commitment problem and its solution via a nonlinear mixed variable programming algorithm. Indeed, the natural formulation of the problem involves both integer and continuous variables thus yielding an optimization problem solvable by a mixed variable algorithm. Our formulation of the problem besides taking into account ramp rate and minimum up and down time constraints, handles the size of the operator and the uncertainty related to the selling prices by defining dierent residual demand curves and using a scenario formulation. The objective function is indeed given by the expected value of the revenue over the dierent scenarios minus a term which takes into account the risk related to the decision. We report results for an operator managing a single unit and three units at the same time
