The number of timesteps is independent of the weather data interval if using hourly weather data. EnergyPlus knows how to interpolate hourly weather data and schedules down to one minute intervals. If properly formulated, a 15-minute scheduled load can easily be modeled.
Interpolating weather data properly is not trivial. If you create a custom weather file with data that have time intervals that are shorter than one hour, then you need to use the same interval in the weather data as you want the simulation to use when stepping through time. The simulation needs to run with timesteps that align with custom-frequency weather data because EnergyPlus is only setup to interpolate hourly weather data.
