If (and that's a big if!) you can get below the DAC rate (i.e, average <250KWH per month) electricity is reasonable here, running about 12 cents per KWH. If you can keep it <150 KWH/month, then it is about 6 cents per KWH.

Even so, gas (propane) is even cheaper. I pay about 6,400 pesos per year, for cooking and hot water for two residences, one of which is using an ancient, inefficient 50-gallon upright hot water heater (as opposed to my on-demand system.) That's $23 per month per household.
