A megawatt-hour (MWh) is a unit used to measure a large amount of energy.
Think of it as the total energy produced or consumed when one megawatt of power is sustained for a full hour. It's a key measurement in the energy industry, from power plants to the electric grid.
It's important to distinguish between power and energy.
Power, measured in megawatts (MW), is the rate at which energy is used.
Energy, measured in megawatt-hours (MWh), is the total amount used over time.
One megawatt-hour is a substantial amount of energy, equivalent to:
Because it represents such a large quantity, the MWh is the standard unit for measuring energy at the utility scale.
While your home electricity bill uses kilowatt-hours (kWh), utility companies and power plants measure energy generation and transmission in megawatt-hours (MWh).
The connection is simple:
1 MWh is equal to 1,000 kWh.
To put this in perspective, the average U.S. home uses about 10.6 MWh of electricity per year.
This highlights the scale of the MWh and its role in tracking the massive flow of energy from significant sources, like wind farms or nuclear reactors, to entire cities and communities.
The megawatt-hour is the primary unit for billing, trading, and planning in the wholesale electricity industry. Its applications are critical for maintaining a stable and efficient power grid.
For example, MWh is used to measure:
This standardized metric allows investors, grid operators, and regulators to accurately evaluate energy assets and ensure grid reliability.
Ever looked at the back of a battery pack and felt confused by the numbers? You're not alone!
One of the most important measurements you'll see is the Watt-hour (Wh).
Think of it as the fuel gauge for your electronic devices. This simple guide will break down precisely what a Wh is and why it matters.
A Watt-hour (Wh) is a unit that measures energy. Specifically, it tells you how much energy a device uses over a specific period.
The concept is simple: one Watt-hour is the amount of energy consumed when one watt of power is used for precisely one hour.
A helpful analogy is a car's gas tank. The Watt-hour rating on a battery is like the size of the tank—it tells you the total amount of energy it can store.
The power your device draws (measured in Watts) is like how fast you're driving and using up that gas.
A battery with a higher Wh rating holds more energy and can power your device for longer, just like a larger gas tank lets you drive farther.
You'll find Wh ratings on many of the rechargeable devices you use daily. It's a key indicator of battery capacity and runtime. Some common examples include:
The Watt-hour is directly related to the joule (J), which is the standard scientific unit for energy. The conversion is straightforward:
This is because a watt is defined as one joule per second, and there are 3,600 seconds in an hour (60 seconds × 60 minutes).
A kilowatt-hour (kWh) is simply 1,000 Watt-hours. The prefix "kilo-" means one thousand.
You're probably most familiar with kWh from your home electricity bill. Utility companies use this larger unit to measure your household's monthly energy consumption.
So, when you see that you used 500 kWh last month, it means you used 500,000 Watt-hours of energy.
