There will be a movement on social media towards serif fonts as more and more people named Al get annoyed with their name looking like the acronym AI

On Monday I’ll be starting at Google DeepMind as a Visiting Researcher for my sabbatical (Jan-Dec 2025). Looking forward to contributing to solving challenging problems in the AI+Optimization for power systems space!

Makes sense!

That almost answers it. If most of the vars are accounted for locally, then it’s justified to have them rated in Watts

I think so, but it’s still not 1.0 pf, right?

Kyri Baker @kyrib.bsky.social · 11/12/2024
Definitely, but how much? Just a ton of cap banks to cancel out hundreds of VAR from the motors?

Kyri Baker @kyrib.bsky.social · 11/12/2024
As a ballpark, if you have a 1 GW data center (with the rating actually in Watts), where 40% of that is the cooling system, and 80% of the cooling system's energy consumption is AC motor loads, assuming an 80% power factor, that's 100's of MVar unaccounted for, making the effective rating ~1.3 GVA

Kyri Baker @kyrib.bsky.social · 11/12/2024
2) Is it just that there's a lot of reactive power compensation so these motors do not pull VAR from the grid and their effective grid impact can just be expressed in watts? 3) If they are pulling VAr, what's the impact on harmonics with this level of reactive power loads? @xiaowang1984.bsky.social

Kyri Baker @kyrib.bsky.social · 11/12/2024
1) Are the load growth numbers we see for data centers *actually* in MW or is this really MVA? If it's actually MW, the consumption is much higher than we thought (/wire sizing/transformer sizing / etc is much higher)

Kyri Baker @kyrib.bsky.social · 11/12/2024
Data center power ratings in MW vs MVA is a good point made by @agelston.bsky.social . If ~40% of a data center's energy consumption goes to the cooling system, and a large chunk of the cooling system's consumption is from AC motors, this is a large amount of reactive power. Which raises questions:

Boom! PJM now forecasts more than 30GW of summer peak load growth by the end of the decade. Summer peak demand: + 6.7GW by 2026 + 17.7GW by 2028 + 31.7GW by 2030

Do AC motors require reactive power? Do data centers have any motors? 😊 Yes

#EnergySky Duke Energy is demolishing a coal plant and putting batteries in its place - a great example of faster interconnection of new energy resources by utilizing existing grid assets! 💡🔌 (yes, they are also building a new gas plant nearby, but baby steps...) www.canarymedia.com/articles/bat...

Ice on power lines can be melted by temporarily overloading the line. High currents = high heat!

If one Amazon AI datacenter consumes around 1 GW, and 1 horsepower is 746 Watts, this means that the datacenter is rated at over a million horsepower That’s a lot of horses And an interesting mental visual

To be obnoxious I’m now only describing the power ratings of common household appliances in terms of horsepower rather than Watts (1 HP = 746 Watts) My frozen burrito requires 2 minutes when used with a 1.48 HP microwave

The net sum of energy savings from energy efficiency upgrades across the years will certainly be offset from increased computing IMHO. But efficiency upgrades have key benefits at the distribution level - it’s not just about the net sum of demand, it’s about the location (and timing).
