Great question! One would intuit that the procurement function of a large organization (like one which operates a hydroelectric dam) would be able to see the value of some kind of industrial sensor that minimizes integration costs and provides them with better understanding of operations data, but practically it’s hard enough to coordinate folks to install conduit to route cables! When it requires political capital to get something as simple as cat-5 installed, clear efficiency gains easily fall off the table. It’s sort of like the infrastructure is “set in stone” and built to service the operations of the dam first, and everything else is secondary, as other commenters have suggested.
