If in your region each private house consumes 3000-5000 kilowatts an hour per month, then I would be mining without fear. In my region, a private house consumes 300-1000 kilowatts an hour per month, and when I transfer readings of 5000-10000 kilowatts an hour per month, controllers will become interested in me. Experts see the average electricity consumption in each home and easily find homes with increased energy consumption.
Ya, this is why I told you every place is different, where I live during summer and winter electricity is consumed like hell because we have no other means of cooling/heating when temps are 40c outside, you bet that every AC is going to be spinning 24/7 when winter comes, we rely on electricity only, in fact, many people use the electric stove to cook (those consume no less than 2kw) so that 1000w that a whole house in your area use is not even enough for a single person here, probably the same for many other places.
And then you have different building sizes in the same area, you find a small house next to a 3-story building when the electric company supplies the small house they need to take into account that one day, the small house could turn into a 3-story building, and then what's even worse, a small house could have an AC in every room, uses an electrical stove to cook food and consuming more than another house that is twice the size.
So with all that in mind, adding a couple of miners will certainly go unnoticed as far as the electrical company is concerned, of course, this changes if the electric company uses some advanced tools to check for load type or harmonics created by PSUs, but just by looking at their amp/kw reading, they can't tell.
