what is your kHW?
How are you monitoring it? via killawatt or separate eb meter ?
You measure the wattage each machine is running at when you build it, with a wattmeter. From there on you can calculate KWH - a machine that was consuming 800W would end up using 0.8 x 24 x 30 = 576 Units of electricity a month.
hmm that was easy.. whats is it per KWH in bangalore ?
and which of your gig is pulling 800W?
