Watts measure power flow. To find the cost you must find the amount of energy, so to do that you multiply the watts by the time the power flows.
1 unit of electrical energy, which costs 5-25 p in the UK, is 1 kilowatt-hour, which is 1 kilowatt for 1 hour, or 1000 Watts for 1 hour, or 100 Watts for 10 hours, or 10 Watts for 100 hours.
In the USA, it's different everywhere, but figure 25¢ per kilowatt-hour.

The cost of a megajoule of electricity can vary significantly based on factors such as location, energy source, time of day, and demand. On average, in the United States, the cost of a megajoule of electricity can range from $20 to $50.
You don't pay for 'watts'. The 'watt' is the rate or speed at which you use energy from the outlet, so the cost depends not only on how fast you use it, but also on how long you use it. Domestic electric rates change drastically depending on where you live, how much you use, and even what time of day you use it. But let's take for an example, 25¢ per kilowatt hour (KWH). That means that if you're drawing energy from the outlet at the rate of 1,000 watts, you'll owe the electric company a quarter if you keep it up for an hour. Your question specified a megawatt = 1 million watts = 1,000 kilowatts. At the same cost of a quarter per KWH, your megawatt would cost: -- About $4.16 for 1 minute. -- About $125 for 1/2 hour. -- About $6,000 for a whole 24-hour day.
"Watt" is a 'speed'. It's used to measure how fast you're using energy.
You don't pay for watts.
You pay for how much energy you use. That's the 'watts' multiplied by
how much time you keep it up. You could take energy at the speed of
a million watts (if your electric meter and house wiring could stand it),
but if you only kept doing that for a couple of seconds, it would cost less
than baking a turkey in your electric stove.
Prices for electrical energy are different everywhere. A rough number
that you can use to get an idea of the cost is
1,000 watts for 1 hour
500 watts for 2 hours
250 watts for 4 hours
200 watts for 5 hours
100 watts for 10 hours . . . . . 1 'kilowatt-hour' . . . . . 25¢
Watts = volts x amps x Power Factor so without more information your question cannot be answered.
To compare the cost of regular electricity to solar electricity, calculate the total cost of installing and maintaining a solar power system over its lifespan and divide it by the total electricity generated. Compare this cost per unit of electricity to the cost of regular electricity per unit from your utility bill to determine which is more cost-effective in the long run.
In 1941, the cost of electricity averaged around 10 cents per kilowatt-hour. However, this cost varied depending on location, usage, and provider.
The cost of electricity per month will depend on factors such as the amount of electricity consumed, the electricity rate charged by the utility company, and any additional fees or taxes. To estimate monthly costs, you can multiply the electricity rate per kilowatt-hour by the amount of electricity used in that month.
The average electricity cost per month can vary widely depending on location, household size, and energy usage. In the United States, for example, the average monthly electricity bill for a household is around $115. To get a more accurate estimate, it's best to review your own electricity bills and calculate your monthly average cost.
In 1990, the average cost of electricity in the United States was about 8.92 cents per kilowatt-hour. However, prices can vary depending on location and provider.
