You think a port and industrial plant that requires 3/4 of a gigawatt of electricity will be built within a limit of less than 4000m from the ocean port? Every port I’ve seen took at least a few kilometers of inland space. I also don’t think a few kilometers makes much of a difference to the light reduction, basically any light at all will harm the telescope.

I am surprised at the “meh” response from the commenters here, they want to build an industrial plant in one of the best places for astronomy. Can’t the plant go elsewhere? The telescope cannot go elsewhere.
