This is in Virgina, which passed the Virginia Clean Economy Act in 2020. This mandated that Dominion (the power company) transition to 100% renewable energy by 2045. Personally, I think this is a good thing in the long run, but in the short run, it means that Dominion has had to invest a lot in building out renewable projects that haven't come online yet.

Lawrence Berkeley National Lab recently did an analysis on electricity prices in the US [1] and found that most of the rate increase in Virginia was attributable to the VCEA, and that load growth had a mitigating effect on price increases.

If you look at the overall report (not just Virginia), the places where electricty costs are rising the fastest are generally not the same places where lots of new datacenters are being built. It's easy to blame datacenters, but there are many factors at play here.

I appreciate that you linked a paper to support your opinion on this matter, though I read the summary PDF a whole lot differently than you did. I’m not sure I’d blame renewables anywhere near as much as you did.

For one thing, energy demand hasn’t been increasing at the consumer level per capita. So you either have a growing population or growing commercial usage (like with data centers) or both driving energy demand.

Is there some literature that points to an idea that it’s faster to build a gas or coal power plant compared to a renewable one? My understanding is that solar is cheaper than gas, right? Even solar plus grid scale batteries are in a similar ballpark. And let’s not forget that other infrastructure like transmission lines and substations do not have any concept of renewable versus not.

The last thing I’ll point out is that we literally have to switch to renewables. There’s no long term versus short term, really, when we think about it. If we don’t make the switch we’ll actually put all of this planet in a lot bigger trouble than asking people to set their air conditioner thermostats a couple degrees higher.

Henrico County currently has 37 data-centres with ~2 gigawatts capacity (expected to reach 3 gigawatts).

Apparently, 1 MW can power approximately 834 homes annually. So 2 gigawatts would be closer to powering > 1.6 million homes.

Surely, that kind of concentrated demand is going to affect electricity distribution costs for everyone, which is what we are seeing now.

As a Virginian, this is good information to have. I see a lot of ludicrous objections to data centers here (the most ludicrous being water consumption, when most of our data centers have closed-loop systems and regardless the humidity here isn't evaporating water).

I've suspected that the energy regulations and the ruling party's close connection with Dominion Energy (the Governor recently attempted to fire the chair of Virginia Tech's board and replace him with the CEO of Dominion) have had an impact on power use more than data centers themselves.

In the long run, green energy and data centers are ultimately going to be complimentary.

One of the biggest problems with investing in a renewable grid is curtailment and managing demand or production spikes. In California, they already have to turn off solar plants during peak hours to help manage overproduction.

Even if you have massive quantities of energy storage, you don't have enough "inertia" in the grid to keep power levels consistent as DC power sources flick on and off.

Data centers can act as massive variable loads that can ramp up or down that turn excess energy into something vaguely profitable. And they can also help to create demand for more supply of intermittent green energy sources.

I'm surprised that the 404 Media article does not mention anything about this. At least, searching for the word "Clean" did not return any results.

a different framing of this same information is that Dominion made dumb investment choices in the 2000s and 2010s, locking into electricity that has a fuel cost.

So don't allow data centers to connect until enough clean energy has been brought online to meet their needs without impacting cost or availability for retail ratepayers. It's easy really. Say no.

It's so strange to me that the argument previously was "we don't have enough energy generation for EVs and heat pumps to electrify and decarbon" but data centers are thought of as must run load that everyone has to suffer in some way to enable (through increased rates or risk of blackouts), when they have very little positive impact for everyone except a small minority investing in them.

> It's easy to blame datacenters, but there are a lot of factors at play here.

It is because they are the problem. We need as much clean energy as quickly as possible to mitigate climate change, we do not need data centers, broadly speaking.

(if you replaced all of the farmland/ag land, the size of the state of Oregon, harvested for ethanol with solar, you would have more electrical generation than all current US electrical generation combined as of this comment; this is simply a question of will, proven by China's solar PV deployment rates [installing ~90-100GW of solar PV per month])

This is the way. Build more data centers and mandate they are powered by solar+batteries/nuclear.

sunshinesnackstoday at 5:28 PM

Capacity shortfalls and needs to conserve (i.e., asking customers to reduce usage) are not necessarily 1:1 with rate increases and overall electricity costs. Especially in the short term.

In other words, large “base loads” like data centers could both reduce the average power bill AND contribute to capacity shortages and load shedding.
