Telescopes are pretty common for this, but lab equipment is too. Universal particle accelerators and stuff

Factories & Food Delivery Kitchens

Medical device manufacturing, kind of.

amateur radio antenna farms also

Solar panel collectives.

Wait... Collective? Not a utility? Are we talking about a neighborhood chipping in on a few panels, or something more interesting?

In nova scotia there are grants to build “community solar gardens”. A 3-6MW solar farm is built somewhere cheap and convenient and then anybody in the community can pay for so many panels and then they get that amount knocked off the light bill as if they had rooftop solar. Idea is it lets people buy solar unrelated to if they rent/own or have a good roof pitch or whatever.
