Some of the users on this forum made posts where they claim to get free power, where do they get this power from?
Some people get power included in rent - In some cases these people loose their free power when their landlord notices a much higher electric bill.
Some people are students and dorm - limited free power from their dorm rooms
Some people are in government housing.
That the case for me, i'm in an apartment owned by a very big company, electric consumption is included in the monthly rent and it is typically cheaper for such landlords to just average out the electric consumption that way rather than install counters for every individual because the electricity here is ridiculously cheap.
So what they do instead is fit the apartment with a couple of 120v 15A breakers and the panel can only support a smallish load after your big electricity spenders (heating, hot water, oven).
And since its cold here 8 months a year, you don't need to pay anything for heating since you have tons of heat available from the ASICs.
So anyways the maximum cost of electricity you could make use of is still a pretty low portion what you pay monthly. As such they don't even need to keep track since they own dozens of apartments in dozens of blocks all over.
