There’s a big discussion on Amazon’s diesel backup plans in Minnesota. I think as long as they meet air permits it’s probably ok to have these. They did go Tier 4 emissions and if you don’t want them running then keep the grid on. Interesting planning discussion. https://www.startribune.com/amazon-must-prove-it-needs-250-diesel-generators-at-becker-data-center-minnesota-utility-regulators-say/601229504
