Cool, but too bad the quality of this article is bad. GW is not capacity, do they actually mean GWh? Or do they mean peak GW power output. Impossible to tell from this poorly written article.
And the mixing 20 million kilowatts hours there, in middle of article, just to get some large numbers.
So from decrypting, it will have hydro storage of 20.0GWh and peak output of 2.8GW, which means that they can run it for 10 hours peak.
I was thinking the same thing. But on closer reading I see the article makes comparison to renewable energy production capacity in the area. So I think by “capacity” they do mean power, as in the project’s contribution to the grid’s power delivery capacity.

Edit: fix in math
“Installed generating capacity” (yes, peak output) it’s near the top of the second list in https://en.wikipedia.org/wiki/List_of_pumped-storage_hydroelectric_power_stations - so this would be the 4th largest in the world

All of the information I found on this project comes from an article from the [South China Morning Post] (https://www.scmp.com/news/china/science/article/3230622/china-breaks-ground-major-project-could-boost-renewable-energy-production-gobi-desert). The Interesting Engineering article copies some passages, including the source article’s choices of the word “capacity”, and the use of “20 million kilowatt hours”.
