Mat files (MATLAB) for electrical load profiles for various usage groups (Tiers) in off-grid electrification contexts. This is based on the Multi-tier Framework (MTF) for household electricity access. The appliances considered are the so-called super-efficient DC appliances. The load profiles are stochastic in nature. These load profiles can be used for system sizing of (renewable) energy systems that can cater to these loads. There are 5 mat files in the dataset: each one corresponds to a tier of the MTF.
