The last year we were in business, 2013, we charged RVers 3 pesos pr KW hour, using good meters we had brought from the states. CFE (electric company) charged us as a business about 3.8 pesos per KW hour. We were going to raise our rate to 4 pesos per KW hour the next year. Usage cost is totally dependant on the amount of electricity consumed. Some Rvers had solar panels and paid no more than 50 pesos a month, others were electricity guzzlers, with extra freezers, electric heaters, and more. Some of these bills were upwards of $1000 pesos per month. Meters were the best thing we did for the business. You use it, you pay for it, and we kept our rates low. I know CFE has raised their rates since, but don't know the business rate at present.
