An S9 with mods costs roughly the same as this space heater below, is more granularly controllable, costs the same or less to run, and will pay for itself in less than a year.

i need a good electricty guide
The S9s run at max 1450 watts. You can manually adjust (with braiinsOS installed) the wattage it consumes. Your electricity provider should give you the costs per kwh. Simply multiply this by the wattage you are running your miner at, to come up with your per hour running cost.
