What does one gigawatt actually mean?

A gigawatt is a rate of power: one billion watts at an instant. If a 1 GW load ran continuously for one year, it would use 8.76 TWh of energy. Power is the speed; energy is the amount accumulated over time.

Here's what matters

The answer changes when these conditions change.

  1. 01MW is not MWh
  2. 02Nameplate capacity is not annual generation
  3. 03A facility may not draw its full contracted load every hour
  4. 04Firm power and variable generation are different concepts
