Demand Estimation for Part of a Town

What part of the world?

Why can't the utilities be of any help?

Are there no meters installed on the houses?

Don't people have to pay for the electricity they consume?

Have a look at some of the bills. The Utility HAS to know how much energy it's customers are using, otherwise they would have no clue how much to charge them.

The answers arent going to be much help:

The utility company sells bulk power for the whole town to another billing company (which only goes around checks meters and collects the charges).

The electric network is somewhat of a mess and distribution substations do not have meters (except for street light SS).

The billing company is unwilling to disclose its customer bills as it regards this as confidential data.

In any case this is a hot tropical climate with air conditioning as main power consumer.

Here's a thought: The power consumption for US military facilities is published in various reports through the GAO. Try searching there for a facility in a climate which most closely matches the one you are concerned with. The bases are essentially small cities, so the data may be good for your purposes.

I don't know if other countries also do the same but it may be worth the effort to get a baseline for your project.

I will also search if I remember tonight. It sounds like an interesting task.

Why not simply do a door to door style survey of electricity usage, where the consumer themselves disclose their electricity usage? You only need to do a sample of a percentage of the town to get an Idea about typical household usage.

I would wager you could obtain all the data you need in a single afternoon if you put on your walking shoes.

Or you could just go look at their meters, and get the data that way. I don't know if this violates any privacy laws or anything, you would want to check with local laws for that first.

Isn't that something? A source of information that is not readily available on the internet! Wow!!

Contact a utility in the same country functioning in another similar town. They can give a value like MW/km^2 or MWh/km^2/year

Getting consumer kWh readings is one thing - a peak kW/seasonal mean figure is a very country and climate related number. It seems the power system is a haphazard and minimal thing. I feel it is probably overloaded - or soon will be. So why not visit each substation which feeds this area and record the transfo ratings. That should give you a peak demand.
