We study the impact of electricity divestments in a stylised model where a dominant producer faces a competitive fringe with the same cost structure and is forced to sell some of its capacity. For a given demand level, the divestment which achieves the greatest reduction in prices can be several times more effective in reducing prices than a divestment of base load (or low-cost) plants. We extend this theoretical result to the case with variable electricity demand by considering a numerical example based on data from the Italian market.
