Electricity usage in villa rental

On holidays in Phuket, we are renting a nice two bedroom villa with pool in Laguna area for a month.
We are being charged at 7 baht per unit of electricity. This seems to be somewhat a standard nowadays.
We have a baby so we do use AC, mostly at night and during the day for naps.
We left a deposit that is quite high and would like to understand what we should expect in terms of typical consumption/cost?

Edit:
Thanks everybody for your response. We ended up being charged over 20000 baht which does seem pretty excessive based on the comments.
Sadely I don’t think there is much we can do aside from paying.
