Substation Generation & Transmission
Megawatts (MW) measure large electrical systems. 1 MW is exactly 1 million watts, enough to continuously power roughly 800-1000 homes.
Understanding Megawatts and Watts
A megawatt (MW) is a large unit of power equal to one million watts ($10^6$ W). The prefix "mega-" represents a scaling factor of exactly 1,000,000. In electrical networks, megawatts are commonly used to describe the generating capacity of large power stations (hydro, solar, wind, coal, and nuclear blocks) and grid transmission lines.
Given the extreme amount of power represented by megawatts, utility operators and plant engineers track these values to size substations and balance utility grids.
1 Megawatt is equivalent to 1,000 kilowatts (kW) or 1,000,000 Watts (W), representing enough instantaneous capacity to power hundreds of homes.
How to Convert Megawatts to Watts
To calculate real power output in Watts from a Megawatt rating, multiply by exactly 1,000,000:
Example: Convert 2.5 MW to Watts:
P(W) = 2.5 × 1,000,000 = 2,500,000 W (or 2,500 kW)
