Abstract: Highlights•A novel Benders decomposition embedding column-and-constraint generation is proposed.•Large-scale network-constrained stochastic unit commitment problems are addressed.•Standard decomposition methods and state-of-the-art solvers fail to find solutions.•The proposed method generates high-quality bounds and solutions for complex problems.
