Meaning of GWe and MWe

GWe and MWe are both units of power that specify electric output capacity, not thermal power.energyeducation+1​

MWe

• MWe means “megawatt electric.”eia+1​

• It represents one million watts of electrical power output, typically used to describe the electrical capacity of a power plant or generator (for example, a 500 MWe nuclear unit can deliver 500 megawatts of electricity to the grid).euronuclear+2​

GWe

• GWe means “gigawatt electric.”acronyms.thefreedictionary+1​

• It represents one billion watts of electrical power output and is often used for large systems or total fleet capacity (for example, a country might have 10 GWe of installed nuclear capacity).abbreviations+2​

Relation to MWt / GWt

• In thermal plants (nuclear, coal, gas steam), you often also see MWt or GWt (megawatt/gigawatt thermal), which describe the thermal power in the reactor or boiler, before conversion losses.energyeducation+1​

• The ratio MWe ÷ MWt is the plant’s thermal efficiency; typical large nuclear plants convert about 33–35% of thermal power to electrical power, whereas modern fossil units can reach around 40% or more.euronuclear+1​
