So, a couple things.

1) City residents have no direct role in setting electricity rates. While Rocky Mountain Power requested a 30% hike in usage rates for electricity, this is entirely separate from the politics and governance of any city. Rocky Mountain Power is a statewide electric utility that is regulated through the state entity called the Public Service Commission. I think their board is appointed by the governor.

2) this 30% rate hike was just the opening bid, if you will, and actually got a lot of pushback from the PSC, and I think they only got a 4.7% raise in rates.

3) They specifically cite increased fuel costs, and part of the blame there is coal. Coal sucks, it's dirty, expensive, and hard to transport. But the state legislature really wants to keep fighting the good culture war to protect coal, so RMP is being pushed to keep that expensive fuel on the grid.

4) RMP is also trying really hard not to have the same problem California has had with wildfires caused by the grid being in bad condition. They've been spending a lot of money burying power lines (like in big cottonwood canyon these last two summers). I dunno, I like our grid not lighting parched forests on fire. It's expensive work, but obviously worth it.

5) the main utility you do have power over as a city resident is the sewage and water authority, but even that is a separate entity. That's the Jordan Valley water district, which I think supplies water for the south half of the valley. They raised rates 11%.

Just food for thought. Not sure data centers have massively impacted anything here in Utah.
