One terawatt hour of energy is equal to a sustained power delivery of one terawatt for one hour, or approximately 114 megawatts for a period of one year: Power output = energy / time 1 terawatt hour per year = 1 × 10 12 W·h / (365 days × 24 hours per day) ≈ 114 million watts, equivalent to approximately 114 megawatts of constant power output.

The scale is a value or expression that is used as a factor to convert a value to its corresponding base unit. Commas may be used as a thousand separator (e.g. 1,000,000) or e notation may be used (e.g. 1e6). Fractions should be used when required for exactness (e.g. 1/12).
If a plant is only needed during the day, for example, even if it operates at full power output from 8 am to 8 pm every day (12 hours) all year long, it would only have a 50% capacity factor. Due to low capacity factors, electricity from peaking power plants is relatively expensive because the limited generation has to cover the plant fixed costs.
One kilowatt-hour per year equals about 114.08 milliwatts applied constantly during one year. The energy content of a battery is usually expressed indirectly by its capacity in ampere-hours ; to convert ampere-hour (Ah) to watt-hours (Wh), the ampere-hour value must be multiplied by the voltage of the power source.

In English, the prefix giga can be pronounced / ˈ ɡ ɪ ɡ ə / (a hard g as in giggle), or / ˈ dʒ ɪ ɡ ə / (a soft g as in gigantic, which shares giga 's Ancient Greek root). [5] A prominent example of this latter pronunciation is found in the pronunciation of gigawatts in the 1985 film Back to the Future.
