Sure, but who pays for it?

If the data center which requires the grid improvements is fully paying for the upgrades, I'm OK with it. OTOH, if they expect to fob off the cost of the otherwise-optional upgrade on the rest of the ratepayers, Fck-NO!

And for those who say "but it benefits the rest of the ratepayers, so they should pay too", NO! If you (person or corp) come in and demand we change something, you should be a net benefit for everyone, not just yourself.

Be a good citizen and help everyone, and you'll find support. Don't, and find people see you as an asshat and you'll find opposition.
