I'm thinking a lot, especially in the winter. Realistically, the guy at the electrical company is not going to call the police because you are paying them more money. If you're stealing the power, then you're toast. Especially in the winter with heaters and christmas lights running, a spike in consumption would not automatically indicate a grow operation and the power company would not know when YOUR usage goes up (more power on an exact 18/6 schedule) unless they were staring at your meter. The only thing would be if the police already suspected you, they could use utility company information against you to obtain a warrant.
