The modellers of MECS Workstream 2.2 are developing an approach for creating load profiles for electricity use for cooking and non-cooking activities at the level of the individual household, and then the aggregate profiles for groups of households and potentially other user types. The paper describes the development of the model, starting from and building on the existing CREST Demand Model. The data requirements are explored, for both baseline characterisation of a household, and to represent the uncertainty and diversity in demand between days and across different households. Illustrative results are reported for household load profiles.
