I prefer it as written, because the additional information of timeframe for measurement indicates that the author is not talking about momentary/peak power.

- j_walter 4y agoWhich indicates the author knows nothing about how semiconductor fabs use power. Power usage is stable with a few percent...and 100MW is really on the low side for this fab. If all 6 phases are completed as they are expected to be...it's more like 250MW.
- totalZero 4y agoI think we can forgive the author for the low estimate considering that this project didn't exist publicly at the time of writing. How does power usage remain stable in a fab? Please say more about how that works.
- j_walter 4y agoMuch of the power is used for keeping air clean with temperature and humidity controlled in a very tight range. More energy is used for water cooling, waste treatment and other facilities. The rest of the power is used for production tools...which when a fab is running are generally consistent users. The power usage will scale with wafer loading, but again advanced fabs like these will run at near 100% capacity for years at a time.
- CydeWeys 4y agoI'd still much rather see "100 MW continuous" over "100 megawatt-hours of power each hour". And the former actually tells you a lot more than the latter, as with the latter it could be bursty (e.g. much more than 100 MW momentary draw), which would be a lot harder to supply. Fortunately for everyone the power draw is actually steady.
