It is the amount of power available that determines how many homes can be supplied. And the answer is complicated, because it is necessary to take what is termed the 'after diversity, maximum demand' (ADMD) of the potential load in order to determine how many homes can be supplied. ADMD takes into account that no single property operates at maximum load on a permanent basis, and when one home owner is at home, several others are at work, etc., so the more properties there are, the lower the actual load will be compared with the theoretical maximum load.

In the very simplest case, with a large number of properties, a figure of just 3 kW per property might be appropriate but, where heavy permanent loads, such as electric heating or air conditioning are used, determining the ADMD is far more complicated because these permanent loads must be taken into account.

As already explained, ADMD assumes that not all properties are utlilising their maximum demand at the same time, so an ADMD might appear to be surprisingly low. So, as an example, let's assume an ADMD of, say, 5 kW, would mean that one megawatt could supply 200 properties.

ADMD figures are important, because they help designers determine what size transformers are needed to supply new developments. The actual load can them be monitored using thermal demand indicators attached to the transformer's secondary conductors and, in practise, these usually indicate that the theoretical ADMD figures, as low as they seem, are surprisingly generous.

An average U.S. household uses about 10,000 kilowatt-hours (kWh) of electricity each year. A watt is a unit of power, or energy per unit time, so it's the rate at which energy is being used. A kilowatt-hour (or 1000 watt-hours) is a unit of energy, so 10,000 kWh is how much total energy each household uses over the course of a year.

This means that each household, on average, uses energy at a rate of about 1 kilowatt (1000 watts, which equal to ten 100-watt light bulbs).

One megawatt is equal to one million watts, so for one instant, one megawatt can power 1000 homes.

A better question to ask is how many homes can a megawatt-hour (MWh) provide with energy for one hour? If one home needs 1 kWh of energy for one hour, then 1 MWh of energy can sustain 1000 homes for one hour.

How many kva in 1 megawatt?

KVA is a rating for complex power (real + reactive power): KVA = KVAR + KW Also, there is 1000KVA in 1MVA, so there's at least 1000KVA in 1MW, but if the reactive power load i

How many kv in one megawatts?

Your question is rather like asking, 'How many metres are there in a kilometre per hour?'! They measure two different quantities, so you can't convert one to the other!

How many amps are required for a megawatt?

  Need to know the voltage. Watts = Amps x Volts.

How many light bulbs can 1 megawatt power?

  This depends on the wattage of each bulb. If each bulb is, say, 100 watts, you can power ten thousand bulbs. To calculate for your own bulbs, divide 1,000,000 watts by t

How many homes will 100 megawatts power?

OVER 9000

What would 4000 megawatt hours power?

My home for ~700 years. The entire USA for ~8 hours. Here's an interesting comparison: About 4,250 space shuttle launches (if we could launch the space shuttle on electricity,

One megawatts is how many units?

  1 MW = 1 000 kW = 1 000 000 W = 1 000 000 J / s = 1 000 000 V*A...   What units are you looking for? The standard unit for Power is W. The power company will charge y

How many volts are in a megawatt?

That would depend on the current.  Watts are a measure of power and are the result of Voltage, times current.  P=VxI Where p=power in watts, I = current in Amps, and V = Vo

How many volts is 1.5 megawatts?

  I looked this up in my Hitchhiker's guide, and it says "42 volts".   Actually, the question cannot be answered because it could be any voltage. Power, measured in wat
