It also mentions power as one of the main costs. He probably did about 30 mins of DD. The power will nearly all come from solar panels that the customers will be paying for. Refer to Elon Musk's recent 1 billion dollar investment in rooftop solar in Mexico for DD purposes,

It will probably produce more power than needed and I believe Mexico is required to buy the extra power back, from the article

an incentive known as net-metering that requires utilities to buy surplus power generated by rooftop solar panels

So that leaves water/sewer and roads and probably a few other expenses.

How much does it cost to build a few roads in mexico to keep up with the growth?

That leaves us with water/sewer. A definite expense worth looking into but nowhere near the cost he was trying to imply.
