How Much Power is 1 Gigawatt? | Department of Energy
To help put this number in perspective, it''s important to know just how big 1 GW is. A watt is a measure of power and there are 1 billion watts in 1 GW. (And if you wanted to break it down even further, 1 million watts = 1 megawatt [MW] and 1,000 watts = 1 kilowatt [kW].) Need a stronger visual? Here are seven examples equal to 1 GW of power:
For example, if we have a system for hydrogen energy storage that has a roundtrip efficiency of 35 percent of so, the amount of electricity required to produce a kilowatt hour of energy output would be the inverse of that. So, one over to roundtrip efficiency would be the value that you will specify for amount of electricity feedstock required.
