Not sure this would be affected:

The Vera Rubin scope, which cost $600+ million, will see first light this July. It's capable of creating a map of the entire available sky every few days. Containing 40B objects, several times more than all previous sky surveys combined.

Half of those images are already threatened by constellations of comm satellites. Another concern is spy satellite imaging. https://archive.is/RzCNI#selection-779.4-779.14

So what compels AES, a US power company, to build a facility there, in all the world ... which would pump out that much pollution?



No, the Vera Rubin Observatory is on Cerro Pachón (https://en.wikipedia.org/wiki/Vera_C._Rubin_Observatory) rather than Cerro Paranal (https://en.wikipedia.org/wiki/Very_Large_Telescope), the maps on the right hand side show the difference (~6° latitude). Similarly I wouldn't expect https://en.wikipedia.org/wiki/La_Silla_Observatory to be affected, but https://en.wikipedia.org/wiki/Extremely_Large_Telescope would be I expect (noting that I haven't seen anything beyond the ESO press release).
