The DDM is an electricity supply model, currently modelling the GB power sector out to 2050. It allows analysis of the impact of different policy decisions on capacity, costs, prices, security of supply and carbon emissions. The DDM employs two key algorithms: • Dispatch algorithm, which models electricity supply and demand
