WHAT IS TWh ? (TERAWATT HOUR)

Energy companies use this measure to describe how much energy they generated, sold, consumed, etc. A terawatt-hour refers to getting power at a capacity of 1 terawatt (10^12 watts) for one hour. A terawatt-hour PER YEAR means the equivalent amount of power sometime within the period of a year.
Saying 1 terawatt-hour-per-year does NOT mean that 1 terawatt was used over the course of only one hour every year (that would be a huge drain on power over a short period of time.) Rather what this is saying is that the power it would take to make one terawatt hour has instead been used over the course of a year.

Perhaps you wonder how big a plant it would take to generate 1 terawatt-hour every year? If you want to assume that the power was generated at a constant rate (e.g. "solve for the capacity of a power plant running at the same capacity over 1 year that generates 1 terawatt-hour per year"), you can do a rough conversion to megawatts. Since a year has 8,765 hours-ish, you could divide 1 terawatt-hour-per-year by 8765 hours and get 114-ish megawatts.


Of course, 1 tera-watt hour per year = 1000 gigawatt hour per year = 1000000 megawatt hour per year...etc.
