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.

Roughly 750,000 to 1,000,000 depending on where that gigawatt is being used. Most US states will be on the lower end, whereas states with high-efficiency, conservation measures, and low per-capita consumption rates like California will be on the upper end.

In the UK many homes have a 240 v 60 amp supply, which is a maximum of 14.4 kW or 0.0144 megawatts. That is usually divided into 3 separately fused circuits: a 30-amp ring circuit for power sockets, a 30-amp cooker circuit and a 10-amp lighting circuit. That is a basic simple supply for a small house or apartment.

A Megawatt can power 1000 homes.

No, it is the unit of Power. Where 1MW = 106 Watt

The same amount of megawatts as it takes to power it for a second, a minute, an hour, or a year. A watt, or a megawatt (million watts), is a unit of power, not of energy.

1 megawatt = 1 000 kilowatts

One thousand kilowatts per megawatt.

The bulb that fused was of 5 megawatts. This is a sentence containing the word megawatt.

Gallons are a measure of volume. Megawatt is a measure of power. The two are not automatically convertible without some other rate.

1000. A megawatt-hour is the energy you'd get with a megawatt of power for 1 hour. Energy = power * time. It's important to note that it's 'megawatt hour' and not megawatt/hour (ie. it's not megawatt per hour).A gigawatt has 1000 times the power of a megawatt. Thus, since the time is the same (both 1 hour), a gigawatt-hour = 1000 megawatt hours.

A typical nuclear power plant produces 500 to 5000 megawatts of power. If we take 2000 as average, an average plant produces 2000 megawatt hours in an hour, or 48,000 megawatt hours in a day. But please note: Technically, this does not answer the question asked, because the question asked for megawatts, not megawatt hours. The question as asked is like asking how many horsepower a car can produce in a day. The measure of electrical output over a period of time is a watt hour, or, in this case, the megawatt hour. So the question answered was, "How many megawatt hours does a nuclear power plant make in a day?"

Most power plants produce several Megawatts of power. A Megawatt is one million watts.

None. First, a megawatt is a megawatt - whether it is nuclear or not. Second, a megawatt is a measure of power while a minute is either a measure of time or of angular displacement. In either case, a watt and a minute measure two different things and, according to the basic rules of dimensional analysis, conversion from one to the other is not valid.

There are 1,000 kilowatts in a single megawatt. These are measures of electrical power which are based on the metric system.

It is not clear what you mean with "units of power".
