# Identifying baseline consumption

I have data of intraday electricity consumptions (by half hours - 48 a day) over a year of 4000 households. Task is to establish baseline consumption of each of these households - possibly also differentiated on seasonality.

One way how to do this would be just taking the mean of the consumption signals. What would be more sophisticated method for this?

I would be very grateful for pointing out to methods I could look into.

• "Seasonality" not only refers to yearly patterns, but also e.g. the typical day-night baseline change. Look into classic statistical literature for this. Mar 19 '16 at 6:49
