How long does a megawatt last

What is a Megawatt Hour. What is a megawatt hour? Clean Home Energy. Energy Most of us have heard about kilowatts, but what about megawatts? What Is A Megawatt?

Bureau of Reclamation , Hoover Dam generates an average of 4. Again, if each home consumes 11, kW-hours of electricity, then the dam is producing enough electricity for about , homes.

Helpful Energy Comparisons, Anyone? A Guide to Measuring Energy. Credit: iStock. To put things into perspective, the modern American home will use around 7, Kilowatt hours of electricity per year. That is far less than 1 MW per month, and for a home to use 1 MW per month, they would have to have all the lights on, with all appliances continuously operating for a very long period.

Another good way to put things into perspective is to understand that 1 MW of power is enough to power 1, homes at a time. However, that number can fluctuate and change depending on the time of year, demands of power, and region. Although folks working in corporate America love their acronyms, the only one that you will want to take away from this article is MWh Megawatt-hour.

It is far easier to say or read MWh versus Mega-watt hour, especially if you are reading a report or speaking to a colleague about the subject for a long period.

A Megawatt-hour, or MWH, is one million watts of electricity used for 1 hour. That said, government sources will always capitalize the first two letters and leave the last on in lowercase. Because of this, it is the most common way to abbreviate Megawatt Hours is MWh. MWH ultimately refers to an hour of electricity equal to this amount.

Before delving into how Megawatts are related to Kilowatt-hours, it is important to realize that these are, in fact, two different measurements. As we went over in the sections above, a Megawatt is a unit of power that is instant; whereas a Kilowatt-hour KWh is a unit of measurement of electricity taken over time. Although these measurements are related in the sense that they are both used to measure electricity, they are different.

One easy way to remember this is by considering that KWh is a unit of energy, referring to how many Kilowatts of energy is used in an hour. MW is a unit of energy per unit time. If you are looking to convert KWh to MW, it can get confusing because you are assuming average or consistent energy consumption over time.

The formula used to do this conversion is this:. Now, if we are talking about how many Kilowatt-hours are in a Megawatt hour, that is by far easier to explain and calculate. As solar becomes a more significant piece of the U. Below, we share how SEIA estimates the number of homes powered per megawatt of installed solar capacity, both photovoltaic PV and concentrating solar power CSP , and the variables that need to be considered in this calculation. The average number of homes powered per MW of PV varies from state to state due to a number of factors including:.

Solar resources are abundant across the United States. The state of Alaska receives the same amount of irradiance as Germany, the world leader in PV deployment. But each state receives different amounts of sunlight, which ultimately impacts the amount of energy generated by a solar energy system. PVWatts version 1 provides system performance estimates from more than testing locations across the U. SEIA used averages from all testing locations in each state to produce a state average estimate.

Electricity consumption varies significantly across all states due in part to differences in demographics, home size and characteristics, and weather.
