Gigawatts is a rate, which gets multiplied by an amount of time to measure an amount of energy.
That's why your energy bill is based on kilowatt-hours. If you have a device that consumes power at a rate of one kilowatt (say a toaster oven) and you run it for one hour, that's one kilowatt-hour (kWh) of energy.
